General Safety Instructions

Intended use

Your Street Machine GT is a bicycle for the

use on streets and surfaced roads.

Legal requirements

When you ride your bike on the public road it

must comply with national legislation and gui-

delines.These will vary from country to coun-

try.

This bicycle is not designed for the use in ra-

cing and off-road riding, for jumping or acroba-

tics, and you must not ride across kerbs, stairs, In general, there are minimum standards for

servation of the prescribed usage and mainte-

nance regulations and instructions.

In most countries, including Germany and the

UK, two independent braking systems are re-

quired. Do not ride with only one brake wor-

king!

The first miles

The first 300 km are an important phase in

which you break in the bicycle. During the first

use of a new bicycle the screws may bed in

and come loose. Cables and spokes may

stretch. Please be very attentive during that

period.

Please contact your local dealer to find out ab-

out your legal obligations.

After 300 km or after two months at the la-

test you will have to take your bicycle to a bi-

cycle mechanic for the first service. Please re-

cord this first service and the tasks performed

in the warranty pass on page 57.This first ser-

vice is the prerequisite for further use of the

bicycle and for your warranty claims.

General Safety Instructions

Be careful that your luggage on the racks or in

Load capacity

the Speedbag is safely stored. Bags must be

tightly fastened to the rack so they can not

move. In no case may loose parts like straps or

belts touch the wheels, the derailleur or the

suspension.

The maximum load (rider + luggage) is 120 kg

(276 lbs).The maximum total weight (bicycle +

rider + luggage) is 140 kg (322 lbs).The lower

limit is valid. It is important to adjust the

spring stiffness of the suspension according to

the load, see the chapter about adjusting the

suspension in this manual, page 16.

We recommend waterproof bicycle bags by

the German manufacturer ORTLIEB.You can buy

them with extra large hooks matching the

oversized tubes of the rack.You can also refit

those large hooks later.

Carrying luggage

Luggage transport is only allowed with the

special rear racks, lowrider racks and luggage

boxes offered by HPVelotechnik .

Take care that your luggage does not cover

the lighting system and the reflectors of your

bicycle and that they stay fully functional.

Maximum load:

Rear rack 25 kg (57 lbs)

Lowrider under the seat 25 kg (57 lbs)

Luggage box (Speedbag) 10 kg (23 lbs)

In case you want to park your bicycle take ca-

re to lean it on a wall or any other solid ob-

ject.With the kickstand alone it is not possible

to safely park a bicycle loaded with luggage, it

could fall down and be damaged.

When a rear rack or a Speedbag is mounted

you have to make sure that when the rear sus-

pension is fully compressed there is at least a

1 cm ( /₃") distance between the rear tire or

mudguard and the rear rack. If you want to in-

crease this distance you have to decrease the

suspension travel of the rear suspension ele-

ment with clip-on spacers. For that purpose

please consult your local dealer.

Additional loading can influence thehandling of

your bike considerably. If you plan on riding

with heavy luggage we advise you to make a

test ride on a street with no traffic to adjust

to the new situation.

The load should be placed as close to the bo-

dy of the rider as possible, since this leads to a

more stable performance.You can also impro-

ve the handling of the bike by positioning the

center of gravity of the luggage as low as pos-

sible, so pack heavy items in the bottom of

your panniers. Hang heavy panniers on the lo-

wrider rack preferably to the rear rack.

Transport in the car

Added parts and accessories

Additional accessories may impair the function

of your Street Machine GT.We advise you to

generally ask your dealer before you mount

any special parts or accessories to your bicy-

cle.

The best way of transporting your bicycle is

inside the car. See that it does not lie on the

derailleur.

If you want to transport it outside the car we

recommend a roof-rack or a rear carrier.Take

care to fasten your bicycle at the frame only.

Caution! Mounting additional parts or ac-

cessories is at your own risk. It is important

that you carefully read the installation guide

of the manufacturer.Additions to the handle-

bar like fairings, handlebar fittings, bottle hol-

ders, etc. may impair your safety due to ad-

ditional loading or clips with sharp edges.

Caution! Do not fasten your bicycle at the

handlebar or, with disassembled wheels, at

the dropouts.The wind causes violent forces

that can stress the parts and therefore may

cause damage. Such damage may not be no-

ticed immediately.

Take care that the handlebar and the suspen-

luggage bags, pumps, pennants, etc.).

parts to the handlebar or the seat that might

endanger the rider through sharp edged or

pointed shapes while steering, getting on and

off the bike or bumping against something.

Do not take kids with you

The Street Machine GT is not designed for the

transport of children.You are not allowed to

mount a child's seat. It is only allowed to

transport children in a trailer that has been

specially designed for that purpose.

Before you purchase a bell or a lighting system

make sure that these accessories conform to

your national laws and regulations.

Fairings

Trailers

As front fairing for the Street Machine GT, you

may use the Streamer offered by HP

VELOTECHNIK. Please take care to assure a good

vision over the fairing and sufficient freedom

of movement below.

You are allowed to use trailers up to 30 kg (68

lbs) with the Street Machine GT. Always check

that the suspension and the trailer still work

properly after you have mounted the trailer.

Take care that the trailer does not damage the

frame in case the bicycle falls over.

Please take into account that any fairing makes

the bicycle more prone to crosswind influen-

ces. In strong wind or gusts of wind unsafe si-

tuations may occur. Please remove the fairing

in such weather conditions before riding.

fork, drive train, suspension elements) should

only be done with original parts by a bicycle

mechanic, since it requires a certain degree of

skill, suitable tools and mechanical aptitude.

Your dealer has carefully finished the assembly,

perhaps altered the spefication of your bike to

meet your special requirements and perfor-

med a test ride. Please make sure that this

pre-delivery service is recorded in the warran-

ty document at the end of this manual.

Any technical change you perform on your

own is at your own risk!

All screws must be checked and tightened, es-

pecially on the handlebar, stem, fork, swing arm

pivot and wheels. Please follow the tightening

torque settings listed in the table on page 55.

Danger! If any part is deformed (e.g. due to

an accident or overload), especially frame,

fork, handlebar, seat mounts, pedals, cranks

and brakes, it is not allowed to use it any

further or repair it. Do not try to straighten

bent parts.You must replace them for your

own safety. If you do not replace a damaged

part it can result in a total failure of the part

and you may be seriously injured!

Rear derailleur and brakes must be checked

and adjusted. Please follow the instructions in

the manuals of the parts manufacturers that

come with this manual.

Screws and bolts

No alteration of parts

Caution! Screws must be tightened with

prescribed tightening torque. In this manual

tightening torques are given in "Nm“

(Newtonmeter).Always use a torque

wrench wherever a torque setting is given in

this manual. Never rely on "feel". Screws

tightened too much or not enough can

break, which can lead to dangerous acci-

dents. In case you don't own a torque

wrench have your bicycle mechanic do the

respective work.You will find a table with

the prescribed torque settings on page 55 in

this manual.

Caution!You are not allowed to perform

any work on the parts of the bicycle, especi-

ally frame, fork, handlebar and seat, which

might endanger their solidity.

These works include drilling holes, welding,

brazing, paint methods that add heat or any

other chemical treatment. If any of these

works is done improperly it may result in a

loss of strength through direct damage or

increased susceptibility to corrosion.

In order to adapt the Street Machine GT as

closely as possible to your body dimensions

and to find the ideal seating position you need

to adjust the front boom, seat and handlebars.

When you pull out the front boom shift the

chain on the smallest chain ring and sprocket

and turn the cranks a little bit backwards whi-

Danger! All procedures described here re-

quire a certain degree of skill, suitable tools

and mechanical aptitude.After any adjust-

ment perform a static check and take a test-

ride on a quiet street, away from traffic. If

you have any doubts please contact your lo-

cal dealer.

Unscrew the clamping screw to adjust the front boom.

Caution! After you have unscrewed the

clamping screws take them off and examine

them for deformation. Lubricate threads and

heads thoroughly.Then re-fit the screws. If

they don't turn easily you will have to repla-

ce the screws.

Adjusting the leg length

In order to check the adjustments have anot-

her person hold the bicycle while you are sit-

ting on the recumbent.

For riders with a short leg length the front

boom has to be cut by a bicycle mechanic, so

that it can be inserted to the maximum. It is

important to trim the end of the tube neatly.

Adjust the front boom in such a way that your The bare metal of the shortened tube end has

a plastic paper sleeve that accomplishes the re-

quired clamping and protects the surface of

the front boom.When the front boom has

been completely removed take care not to da-

mage the plastic paper adding while inserting it

again.

While you are pedaling, the ball of your foot

should be positioned over the center of the

pedal axle.

It is important that your leg is not fully straigh-

tened when the crank is in the foremost posi-

tion. If the distance is too great it is difficult to

overcome this dead point, pedaling becomes

uncomfortable and there is too much strain on

the sinews of your feet and legs. If the distance

is too short you may suffer from knee pain or

your legs bump on the handlebar.

Caution! The minimum insertion depth of

the front boom into the main frame is 10

cm (4"). In no case may the end of the front

boom be visible in the clamping slot when

you look at the main frame from below, sin-

ce it may result in a damage of the frame.

Adjust the front boon so that your knee will not be fully straighte-

ned when pedaling.

The rear end of the front boon must never be visible in the clam-

ping slot.

Adjust the front boom so that the bottom

bracket axle is horizontal when you look at it

from the front. For that purpose look beyond

the bottom bracket shell at the rear wheel ax-

le and align the front boom parallel to it.Align

your eyes with the bottom bracket axle and

not the front changer tube above.Then sit on

your bicycle and check the position. (Hint:

When you have the impression that the bot-

tom bracket is turned alternately to the left

and then to the right when cycling you will ha-

ve found the correct middle position).

Danger! After the chain has been shorte-

ned it has to be closed with a special closing

link or a chain riveting tool that expands the

rivet while riveting (i.e. ROHLOFF- Revolver).

A poorly joined chain may break and thus

lead to a fall. Have adjustments of the chain

length or the changing of the chain be done

by your bicycle mechanic.

Caution! Take care that the chain tubes ha-

ve at least a clearance of 5 cm (2") to the

rear derailleur and the front changer even

under maximum tension of the chain and

that the tubes stay tight in their fastenings.

Shorten the tubes if necessary. If the end of

the chain tube gets into the rotating drive

train it could be locked-up and destroyed.

The end of the rear chain tube has to be

tightly secured with a cable tie behind the

retention spring.

Tighten the screw with a torque wrench (tigh-

tening torque 14-16 Nm). On your first ride

check whether there is sufficient clamping.

Danger!If the screw is tightened too much

or bent, the screw can break! If the clamping

is insufficient the front boom can turn du-

ring a ride which may cause your feet to slip

from the pedals and lead to a dangerous fall.

In order to move the bottom bracket tube

your specialist dealer has to adjust the chain

length. By default the Street Machine GT co-

mes with a very long chain so that the adjust-

ment range of the bicycle can be fully used wi-

thout the need to lengthen the chain.

After the first adjustment of the leg length that

you have done together with your specialist

dealer while handing over the bicycle, the

chain has to be shortened so that the arm of

the derailleur is not fully turned forward while

shifting on the big chain ring in front and the

big sprocket behind.The derailleur must still

be able to compensate a length change of the

chain of at least 4 cm. In order to choose the

right chain length, please consult the manual of

the derailleur manufacturer.

Check that there is at least a 5 cm (2") clearance between the

end of the chain tube and other parts of the drive train.

Adjusting the leg length

After you have adjusted the front boom you

should seal the gap in the clamping slot bet-

ween the front boom and the main frame with

wax or silicone in order to protect your frame

from the penetration of water and dirt and

hence damage through corrosion which may

lead to a broken frame.

We recommend you to slightly readjust the

front boom every 3 months so that knee, mus-

cless and ankles will be used differently, and

you might find a more comfortable and more

efficient riding position.

A wrong adjustment may lead to pain in your

knees and inefficient pedaling. In addition we

recommend to ride with a high pedaling ca-

dence, which means to pedal fast and with litt-

le pressure. Pedaling with too much pressure

may also lead to pain in the knees.You will find

more information about this on page 26.

Adjusting the seat position

Adjusting the seat angle

Adjusting the seat with mounted

A big advantage of the Street Machine GT is

that you can adjust the seat angle very quickly.

For beginners or rides in the city you can

choose an upright seat position for a better

view, and for longer travels you can choose a

flat position for better aerodynamics.

Speedbag

A mounted Speedbag impedes the access to

the rear quick release for the adjustment of

the seat angle.

Therefore you should adjust your seat prior to

mounting the Speedbag.You have to screw the

Speedbag to the seat afterwards.

The seat is fastened with two quick release le-

vers on slotted aluminum seat mounts.You can

adjust the angle by 10 degrees by simply ope-

ning the two quick release levers. In the me-

dium seat position the angle is about 35° from

horizontal.

It is possible to simplify the adjustment of the

seat by replacing the knurled nut of the rear

quick release by a big washer and a self-locking

hex headed nut.This allows you to tighten or

loosen the seat mounts with a tool you insert

from behind.

Because of the special cam shape of the two

slotted holes, the seat effectively pivots around

a central axis, approximately in the area of the

lower lumbar vertebrae.This is the place whe-

re you support the biggest part of your peda-

ling force while riding, so this point determines

the distance to the pedals.The advantage of

this design is that you adjust the distance from

the seat to the bottom bracket only once as

described above, a change in the seat angle

does not require an adjustment of the front

boom.

Caution! The two quick releases have to be

closed firmly (tightening force 15-20 kg / 45

lbs) to safely hold the seat.You are not allo-

wed to open them while riding.After they

have been closed the imprint "close" must

be visible. If the quick releases are not tigh-

tened appropriately the seat can move while

riding and you may no more be able to

handle your bicycle.

Adjusting the handlebars

Tighten the screw with 14-16 Nm. Check the

clamping by trying to turn the stem against the

front wheel. Remount the rubber cap.

Adjusting the handlebars

As standard equipment the Street Machine GT

comes with under seat steering.The position

of the handlebars is under the legs.

Alternatively, we offer above seat steering

where the handlebars are above the legs.

b)Adjusting the stem - A head stem

Danger! Adjusting the stem also requires

some work at the steering head bearing. In

case of assembly errors the danger of acci-

dents is increased. If you are in doubt have

your bicycle mechanic adjust the stem.

The handlebars are connected with the front

fork through a stem.There are different stems

for under seat steering in use:

a) a vertically adjustable stem that is inserted

in the steerer tube

b) a stem that is clamped onto the steerer

tube and at the same time fixes the

steering head bearing (so called "A head

stem")

The A head stem is clamped onto the steerer

tube with two screws.At the same time it fi-

xes the steering head bearing.

Adjusting the stem

Starting at the fork, both stems have to point

backwards to the seat.

Danger! The hex-headed screw in the cap

adjusts the play of the steering head bearing.

This screw does not help to clamp the stem

tightly to the steerer tube. It does not secu-

re it against turning.Take care that both

clamping screws on the side are tightened as

prescribed after you have finished your

works at the stem. Otherwise the stem may

turn while riding and cause an accident.

a) Adjusting the stem - vertically adjustable

stem

Remove the rubber plug and undo the hex-he-

aded screw that lies below. If the stem still

doesn't move then you can undo the clamping

in the stem shaft with a gentle punch on the

Allen key.

Mount your bicycle, fix the front wheel with

your feet and align the stem parallel to the

front wheel.

In case you only want to adjust the already

mounted stem parallel to the front wheel you

don't have to undo the screw on the cap.

At the same time insert the stem so far in the

steerer tube that the handlebars move freely

under the seat even when the seat is in its

most upright position.The minimum distance

between seat and handlebars is 5 mm.Take ca-

re that the minimum distance between the

handlebar clamping at the stem and the frame

of your bike is 5 mm.

Mount your bicycle, fix the front wheel with

your feet and align the stem parallel to the

front wheel.

Then tighten both clamping screws alternately

with 8-10 Nm. Check the clamping by trying

to turn the stem against the front wheel.

Check the play of the steering head bearing,

see below.

Adjusting the head set bearing play

The head set bearing has to be adjusted so

that the fork with the front wheel turns easily

without showing play.

Caution! The stem fixes the steering head

these parts are no longer supported and

may fall down off the frame. Hold the fork

with one hand or secure the fork e.g. with a

cable tie at the frame.

To check the bearing play pull the front brake

and grab with your other hand the upper bea-

While riding you should allow your arms to

rest in a relaxed position on the handlebars.

Do not pull on the handlebars. If the handle-

bars turn in the stem clamping during the ride

stop immediately and tighten the clamping

screw of the handlebars again. If the handle-

bars turn in a stem that is not sufficiently

By changing the angle of the handlebars you

can adjust the position of the grip to the

length of your upper body and your arms.

Most riders are comfortable with a 45° angle

so that the grip points diagonally to the front

and up.The more upright the grip position the

lesser is the maximum possible cramp of the

position. Check that the stem clamps the

handlebars exactly in the middle.Tighten the

clamping screw with 10-12 Nm. Check the

correct clamping of the handlebars by moun-

ting your bike and pulling the handlebars. In

doing so they must not turn.

Caution! After you have adjusted the hand-

lebar position you also have to adjust the

length of the brake cables and shifter cables.

The cables have to run smoothly without

any sharp turns and they may not be bent or

stretched beyond their elastic limit when the

handlebar is at maximum cramping.Also avo-

id large arches that could be caught up in

other parts.

Please take care that the clamping area of the

stem is thoroughly trimmed and does not have

any sharp edges which may lead to a rupture

of the handlebars.

You can make smaller adjustments by moving

the cables in their guides at the frame and the

handlebar, so that there is enough room at all

mobile parts. For this purpose you can move

the cable for the front changer a little bit into

or out of the frame. If this proves not to be

sufficient you will have to have your specialist

dealer shorten the cables or replace them by

longer cables.

Danger! Every time you undo the clamping

connection you'll have to check the screw. It

must not be bent, corroded or damaged. In

addition to this you'll have to check the wel-

ded-on thread nut of the clamping.The thre-

ad must not be damaged and the screw

must turn easily. In case of damage or defor-

mation you have to exchange the clamping

screw immediately.

Handlebar grips

The grips on the handlebar are susceptible to

wear and tear. Have your grips replaced by

your bike shop once they don't feel comforta-

ble anymore.The grips always need to be atta-

ched firmly to the handlebar.

Adjusting the suspension

Purpose of the adjustment of the

suspension

Suspension and damping

The suspension systems of the suspension fork

and the rear swing arm are fitted with the ac-

tual springs and dampers, which are mounted

separately.

Your Street Machine GT is fitted with a sus-

pension fork for the front wheel and a rear

swing arm for the suspension of the rear

wheel.This system compensates small bumps

on the road so that riding is comfortable and

the strain on your bicycle is reduced.

Often, the terms suspension and damping are

used inappropriately in everyday language.

The spring is the elastic element that com-

presses and decompresses through the load,

which occurs on bumpy roads.While decom-

pressing the spring releases the same energy it

has saved during compression.

A well-adjusted suspension improves the trac-

tion of your bicycle. Especially in bends this

does not only allow a higher speed but it also

increases your safety.

In order to achieve maximum riding comfort,

the suspension settings have to match your

weight as well as the road condition.

The Street Machine GT is fitted with coil

springs of steel at the suspension fork and the

rear fork swing arm. In addition to this the

suspension fork contains springs made of mi-

crocellular foam elastomers. (MCU).

The goals of the adjustment are:

G maximum use of the available suspension

travel without the suspension frequently

bottoming out

G quick reaction of the suspension without

obvious oscillation after having passed

a bump

G avoiding self inforcing oscillations, that means

increasing oscillations of the suspension

system due to pedaling influence, rhythmic

body movements or permanent wavy

underground

The damper slows down the process of com-

pression and decompression.That means that

the bicycle after having passed a bump does

not immediately "spring" back to the initial po-

sition or even further than that.The damper

converts spring energy into friction and finally

into heat, and thus takes away energy from the

suspension system.That way the damper pre-

vents that the spring swings uncontrolled after

an initial stimulation. In addition the damper

helps to avoid self inforcing oscillations of the

suspension that may be caused by reoccurring

stimulation like pedaling forces within a crank

revolution or the rhythmic up and down mo-

vement of the legs.

The hydraulic damping of the rear suspension

is adjustable, in case you have mounted the op-

tional suspension element DMM ST8ARC.

You should always set the damping as low as

possible to give the bicycle the possibility to

quickly react even to several bumps in a row.

Adjusting to load

The luggage carriers of the Street Machine GT

are mounted to the suspended part of the fra-

me.That way your luggage is also fully suspen-

ded and it spares the material. Most notably,

even under heavy load the suspension will

compensate an uneven road much better and

quicker compared to a design where the lugga-

ge carrier would be mounted to the unsuspen-

ded parts, e.g. the rear swing arm.

You can ride the Street Machine GT with a

considerably lower damping than for example

a MTB: due to the relaxed and steady position

of the body the recumbent does not experien-

ce extreme variations in the load as it is

known from dancing on the pedals while riding

uphill on a mountain bike.

Additional luggage changes the load of the

wheels and their suspension.The suspensions

are more compressed through the load.That

way, there is less suspension travel for bumps

while riding.Your suspension could seize up

more often.

In addition to this, varying pedaling forces have

very little influence on the suspension of the

bicycle due to the No Squat design of the sus-

pension system of the Street Machine GT. So

when you adjust the damping, always start with

a low damping.

The suspension of the front wheel is less affec-

ted since luggage at the rear rack almost only

puts weight on the rear wheel. Only in case of

heavy luggage on the lowrider under the seat

is there an influence on the front wheel.

It is necessary to choose the correct spring

stiffness to have a well operating suspension

system.The spring stiffness is a measure for

the compression of a spring at a certain load.

It is either given in "N/mm" (Newton per

Millimeters) or "lbs./inch" (Pounds per Inch).

Sometimes you only find "lbs." printed on the

springs.

In order to compensate the variations in the

load you can change the pre-load. For details

see the following chapter.

The suspension is designed in a way that the

spring compresses considerably when you

mount your bicycle.This is called negative sus-

pension travel and it enables the bicycle to de-

compress on bumpy roads. (Which is in fact a

definitely positive feature.)You should choose

a spring stiffness with which this negative sus-

pension travel takes up around 30% of the

overall suspension travel.This value usually

provides a very comfortable ride on your fully

suspended recumbent bike designed by HP

VELOTECHNIK.

Theoretically this can compensate for a load

change of approx. 10 kg (23 lbs) at the rear

wheel. In case of higher variations in the load

you would have to exchange the spring for an-

other spring with another spring stiffness. In

practice you can often do without it: the

Street Machine GT offers with 90 mm (3 /2") a

lot of suspension travel for a touring bike.

When you choose the spring stiffness so that

the full 90 mm are at your disposal when your

recumbent is under maximum load, you will

have a somewhat smaller but still very comfor-

table suspension travel when you ride without

luggage.

Adjusting the suspension

Adjusting the suspension fork

The front fork of the Street Machine GT co-

mes with telescopic suspension forks from

BALLISTIC or MEKS.

At your request different types of suspension

forks can be mounted to your Street Machine

GT, please notice the manuals of the suspen-

sion fork manufacturer that are possibly enclo-

sed.

Turning knob for the pre-load of the suspension fork BALLISTIC

XL-600All

The suspension travel of the BALLISTIC fork is

approx. 40 mm (1 /2"), of the MEKS fork ap-

prox. 50 mm (2").

The suspension fork should compress by 30%

while mounting the bike, which corresponds to

10-12 mm.

You set this value by adjusting the pre-load of

the spring, provided you chose the correct

spring stiffness (page. 19).

Every model has a turning knob on the fork

legs that allows a simple adjustment of the

pre-load.

Turning knob for the pre-load of the suspension forks MEKS

Carbon AC and MEKS Carbon All

The suspension forks BALLISTIC XL-600All and

MEKS Carbon All have springs in both fork legs,

the suspension fork MEKS Carbon AC has

springs only in the left fork leg since the other

fork leg contains a hydraulic damping cartrid-

ge.

The knob must turn easily. If a knob does not

turn any further you have reached the final po-

sition. In that case turn the knob again in the

other direction about half a turn.

Do not turn the knob by force beyond the fi-

nal position since this will damage the plastic

thread inside.

By turning the knobs clockwise you increase

the pre-load, by turning them anti clockwise

you decrease the pre-load.

It is sufficient to set the pre-load in the two

fork legs to approximately the same level. It is

not necessary to match them exactly.

The suspension fork MEKS Carbon AC is fitted

with a hydraulic damping unit. On the right

fork leg is a turning knob to adjust the dam-

ping.

Choosing the spring stiffness of the

suspension fork

Your suspension fork comes by default with a

standard spring that covers a wide range of lo-

ad and riding styles.

If the spring stiffness should not meet your re-

quirements after adjusting the pre-load or if

the suspension bottoms out too much, you

can order a spring with another spring stiff-

ness through your dealer and have it mounted

there. For more information see page 41.

It is not important to exactly follow the re-

commended values for the negative travel, rat-

her follow your feeling how the bicycle beha-

ves during a ride, depending on the road situa-

tion.

Turning knob for the adjustment of the damping of the suspen-

sion fork MEKS Carbon AC.

You increase the damping by turning the knob

clockwise.

While riding you should only seldom feel the

suspension bottoming out. However, in case

this never occurs the spring might be to hard

which means you don't use the total suspen-

sion travel.

We recommend you to start with the lowest

possible damping. Only when the fork oscilla-

tes more than once after you have gone over a

bump should you increase the damping.

When the fork works fine when passing a sin-

gle bump but stiffens distinctly when passing

several bumps that come quickly in a row, the

damping is too high. However, when the fork

"jumps" during the rebound movement the

damping has to be increased.

Adjusting the suspension

Adjusting the rear suspension ele-

ment

Danger! Take care that the rear wheel or

mudguard never hits frame, rear rack or lug-

gage box while the suspension is fully com-

pressed.

Danger! While adjusting the rear suspen-

sion element never load the bicycle e.g.

through resting on the seat or loading the

rear rack when your hands or tools are clo-

se to the suspension element. Otherwise

your hands may get caught and squeezed

when the suspension compresses.

Therefore relax the spring completely by

turning the spring retention disc on the

thread of the spring element as far as it will

go (before this, push the possibly existing sa-

fety spring ring from its slot in the threaded

section as far as it will go). Have a second

person mount the bicycle and make the sus-

pension bottom out by leaning on the seat

or the rear rack.

For the rear suspension of the Street Machine

GT a steel spring is combined with a hydraulic

damping unit in a spring element.The damping

results from fluid friction of an oil flow

through thin holes of a throttle valve in bet-

ween two chambers inside the damper.A

slightly noticeable sound that may occur from

this oil flow is normal. Due to the fluid friction

the spring element may heat up, therefore

touch the spring element after a ride very ca-

refully.

If the distance between the wheel or mud-

guard and the frame or rear rack is smaller

than 1 cm you will have to mount an addi-

tional spacer. In case you don't, the mud-

guard may break suddenly or the rear wheel

might be blocked which can lead to serious

crashes.

Danger! The suspension elements are filled

with gas under high pressure. Never try to

open the damper or to remove the screw at

the gas tank. Inside the damper there are no

user serviceable parts. In case of damage

you will have to take the complete suspen-

sion element to your dealer.

The suspension travel is adjusted by adding clips to the piston

rod of the spring element.

By adjusting the damping you can adjust the

performance of the suspension precisely to

your individual riding situation.A rough street

with many harsh bumps that occur in a row or

even cobblestones needs a low damping rate

while a road with long stretched bumps that

occur more regularly needs a stronger dam-

ping to achieve a smooth road holding.

Adjusting the damping (optional)

Your Street Machine GT comes standard with

a suspension element of which the springs can

be exchanged and the pre-load adjusted.The

damping in this suspension element is set to a

fixed rate.

When you add a lot of luggage you will need

to adjust the spring stiffness; in that case an

adjustment of the damping may even give you

more riding comfort.

Finally, the oil used in the damper becomes

thicker and more viscous at lower temperatu-

res, which can be compensated through a

change in the damper setting.

Suspension element DV-22 with fixed damping rate.

Please note that you can seriously spoil the ri-

ding comfort through a bad damper setting, es-

pecially through unsystematic playing with the

knobs that may result in much to high damper

values. In the worst case the suspension ele-

ment will neither compress nor decompress. If

you are in doubt please consult your local dea-

ler.

As an upgrade option a rear suspension ele-

ment with separately adjustable compression

and rebound damping is available. In addition

to this the suspension element has a bigger gas

volume in the damper that leads to better sus-

pension performance due to lower pressure

and thus less stiction of the piston.

Adjusting the compression damping

In order to adjust the compression damping

turn the knob on the downside of the suspen-

sion element, when you look in driving direc-

tion it is at the front of the suspension ele-

ment.

You get minimum damping when you turn the

knob as far as it will go, when you look at the

knob from the underside turn it clockwise.

When you unscrew it the damping increases,

the compression movement is slower, the

damping gets harder.

the rear end of the suspension element.You

The writing on the knobs can be sometimes

confusing, it is easier to remember the follo-

wing:

Adjusting the rebound damping

The rebound damping prevents an eventual

"jumping" of the rear wheel and provides a

good traction. By improving the road surface

contact the suspension of the Street Machine

GT also increases your riding safety.

The farther out the knob the more damping you

get. Unscrew the knob as far out as it will go me-

ans that nothing moves anymore.

A higher damping value prolongs the time until

the decompression movement is finished. Only

then can the suspension compensate the next

shock with the full suspension travel.

Therefore, when you ride on very bumpy

streets with shocks that occur fast in a row

you might want to use a lower damping value.

Adjusting the pre-load of the sus-

pension

The pre-load determines how far the suspen-

sion compresses when you are sitting on the

bicycle while standing still.

For the rear wheel the same guidelines as for

the suspension fork are valid: for maximum ri-

ding comfort the suspension should compress

by about 30% of the total suspension travel

while you mount the bicycle in driving posi-

tion.

Turn the knurled ring to adjust the pre-load.

For that purpose measure (similar to the me-

thod described for the suspension fork) the

distance between the two suspension element

bolts or between rear rack and rear wheel

while the bike is unloaded as well as while sit-

ting on the bicycle in riding position.Also take

into account possible luggage. Find out the to-

tal suspension travel possible for your bicycle

with the method described above, depending

on the mounted add-on-parts and the spacers.

The static compression should amount to ab-

out one third of the overall suspension travel.

Danger! The adjustment ring has always to

be screwed so far towards the spring that

the spring has no play when unloaded.

Otherwise the adjustment ring could come

loose through shocks while riding so that

the slotted rear spring retention disc comes

off. In that case the suspension element may

be damaged or the rear wheel could hit the

frame or rear rack, which may lead to se-

rious falls.Always have an initial pre-load of

at least half a turn on the spring.

You can affect this negative suspension travel

depending on how much you weigh and how

much you load your bike either by adjusting

the suspension pre-load for fine tuning or by

replacing the spring with a spring with a diffe-

rent stiffness in the rough tuning.

The adjustment ring should be turned no mo-

re than five turns (measured from the relaxed

position) towards the spring. If the suspension

compresses still too far even after six turns,

the spring is too soft and has to be replaced

by a harder spring.A too big pre-load of a too

soft spring does not take advantage of the full

comfort potential.

In order to adjust the suspension pre-load

turn the knobby adjustment ring on the threa-

ded part of the suspension element by hand.

Turning the adjustment ring clockwise (looking

at it from behind) reduces the preload, turning

it anti-clockwise you screw the adjustment

ring towards the spring and increase the sus-

pension pre-load. It is helpful to turn the

spring together with the adjustment ring.

You will find more information on changing

springs in this manual under "Maintenance and

Care", page 45.

Learning the new riding technique

Your new bicycle has been assembled by your

dealer and adjusted together with you as des-

cribed on the previous pages under "Adjusting

your new bicycle". Before you mount your bike

and enjoy your first ride please make yourself

familiar with the instructions on the riding

technique and the handling.

Look ahead in the direction where you want

to ride, not on the handlebar, at your feet or

the front wheel.

In order to stop brake carefully with both bra-

kes until the bicycle has come to a complete

stop. Only then do put a foot on the ground

and keep the balance.

Learning the new riding technique

To ride this recumbent you will have to make

yourself acquainted with the different riding

position. Make sure that you and all other fu-

ture users of this bicycle will have read this

manual carefully prior to the first ride. If you

are in doubt please consult your local dealer.

Danger! Never touch the ground with your

feet while the bicycle is still moving.The feet

could be caught on the ground and be pulled

backwards which could lead to a serious in-

jury.

Before the first ride the users of this recum-

bent have to practice and make themselves fa-

miliar with the different handling.We recom-

mend to practice on a quiet road away from

traffic. Before you ride the bicycle in traffic you

must master the handling completely.

Danger! With a compact recumbent like

the Street Machine GT it is possible that a

foot of the rider contacts the front wheel

when riding sharp corners with a pedal in a

low position.You will have to avoid this situ-

ation at all times since in extreme situations

it may lead to a fall and injuries.

Go to a road where you can ride straight ahe-

ad without being hindered. Hold your bike at

the handlebars and pull a break.Then mount

your bicycle and lean back. Leave one foot on

the ground and put one on the pedal.

To control the bicycle you will therefore ha-

ve to apply the following cornering techni-

que: when you ride a curve stretch the leg

on the inside of the curve, stop pedaling, on-

ly then start steering into the curve. Only

when you ride straight ahead again should

you resume pedaling.

Therefore rotate the crank in the top position

so that you can pedal immediately with power.

Try to keep your balance in that position.

Assure yourself that you can stop whenever

you want to and hold the bicycle with one

foot on the ground.When you feel safe put

pressure on the pedal, loosen the brake, pedal

with a lot of force and immediately put your

second foot on the other pedal.

Danger! Please note that due to your low

seat height other road users may notice you

very late. Ride anticipatory with this in mind.

This is especially important while riding in

darkness.You yourself have a much better

view than others perceive you. Ride defensi-

vely.We recommend you to mount a well vi-

sible and reflecting flag to the bicycle while

using it in traffic. Please ask your dealer for

more information.

Do not care on which side of pedal you are

currently pedaling in the beginning. Hold the

handlebar loose but steady and accelerate with

a few pedal strokes.Your bicycle needs speed

to stabilize.

Strain, riding freehand, way of riding

Your pedaling cadence should stay between

80-100 revolutions per minute and not fall be-

low 60 revolutions when going uphill. If neces-

sary have your specialist dealer adjust the gear

range to your riding style and the terrain you

usually ride.

Slowly increase the strain

We recommend you to perform only short ri-

des without much power during the first

weeks.

Always use a low gear and ride with a high pe-

daling frequency. Only after having acquired so-

me training do increase the strain slowly.

You will find many tips on proper training for

cyclists in miscellaneous books and magazines

for cyclists.

When you ride on a recumbent you use other

muscles than on a conventional bicycle, and

they have to be trained first.The very high po-

sition of the bottom bracket requires your

muscles and blood transport system to slowly

familiarize with the new position.

In case of persistent problems please consult

your doctor.

Do not ride freehand

In case of an overload the blood circulation in

your legs may be affected which shows in loss

of power, a prickling in the toes, falling asleep

of the legs or cramps.When you have a sporty

way of riding it can take up to 6 months until

you have become accustomed to your new re-

cumbent.

Danger! In order to ride safely you have to

keep both hands at the handlebar. Even

when signaling keep at least one hand at the

handlebar. Otherwise, unforeseen bumps in

the road or oscillations of the steering may

lead to a serious fall.

way of riding, Quick release levers

In the second half of the lever's movement the

force on the leer should increase considerably,

corresponding in the end to 15-20 kg (46 lbs).

Caution! Always carry your bicycle over

stairs and curbstones. Do not ride through

big road holes. Especially when road holes

are filled with water it is very difficult to

guess how deep they really are. In case you

hit such an obstacle frame and fork may be

damaged which can result in a serious fall.At

first, the damage may be unnoticed. Please

check your bicycle immediately for deforma-

tions and cracks. If you are in doubt please

consult your local dealer.

In its final position the lever should lie parallel

with the bicycle and should not stick out to

one side.

Check the security of the lever by attempting

to twist the lever. If the lever can be made to

pivot around in a circle the clamping is too

loose.You must re-open the quick release,

hold the lever and increase the clamping ten-

sion. Do this by screwing the adjustment nut

on the other side by half a turn. Close the le-

ver and check the clamping anew.

Quick release levers

Quick release levers hold wheels and seat in

position.

Finally, check that the part being secured is

firmly fixed: Lift each wheel several inches off

the ground and give it a slap onto the tire

from above.A properly fixed wheel will remain

secure in the frame's dropouts.

Danger! An incompletely or improperly

closed quick release can result in parts co-

ming loose, and hence in a crash, possibly re-

sulting in serious injury.

The dropouts of the fork of your Street

Machine Gt are designed as safety dropouts.

Therefore you always have to loosen the clam-

ping nut of the quick release when you take off

the front wheel.When you reassemble it do

not forget to tighten the nut again!

A quick release lever consists of two basic

parts: the lever on one side provides the clam-

ping force.With the adjusting nut on the other

side you adjust the clamping tension on the

screw thread.

To open the quick release, move the lever

away from the frame. In doing so the inscrip-

tion "open" should be visible on the lever.

Parts that are fastened with a quick release

open easily.Thus, they are more susceptible to

theft.Therefore, always secure the wheels with

a lock when you park your bicycle. It is also

possible to exchange the quick releases with

special security screws (e.g. from PITLOCK or

KRYPTONITE) that can only be opened with a

special tool. For this please consult your local

specialist dealer.

To close the quick release, move the lever with

power in the other direction so that the word

"close" is visible on the outward side of the le-

ver.At the start of the lever's motion, for, say,

half of its movement, the lever should move

very easily, without any clamping action.

Brakes

Danger! Please note that the braking

distance is much longer when it is wet or

when the bike is heavily loaded.When riding

on wet, sandy, icy or slippery roads you have

to use the front brake very carefully to avoid

that your front wheel slips. If it does so you

will no longer be able to handle your bike,

which might lead to a serious fall.

The Street Machine GT is equipped with a po-

werful high-quality brake system.You may

choose between rim brakes and disc brakes.

Please do read the separate manual that co-

mes with your bike for details.

Make yourself familiar with the braking system.

Remember which lever pulls the front brake

and which the rear brake.

Do not brake in a bend, always brake before a

bend. Braking increases the risk of slipping.

Especially when it is wet the rear wheel imme-

diately slides out of the bend while braking

and this can result in a serious fall!

If the arrangement of the levers does not cor-

respond to what you are used to, please have a

two-wheeler mechanic change it. Please con-

tact your local specialist dealer whether there

exists any legal requirement for the arrange-

ment of the brake levers in your country.

Danger! In case you get into a situation like

that during an emergency stop you have to

let go of the brakes immediately, balance

your bicycle and brake again. If you are not

familiar with the brakes we recommend you

to train at first at low speed and with little

braking effect until you find the correct dose

for an emergency stop.

Note that the front brake is the most effective

brake on the Street Machine GT.With the

front brake, you achieve a much higher braking

effect than with the rear brake.The rear wheel

has a tendency to lock up and slip on the pa-

vement even under low braking forces.The

braking effect of modern brake systems can be

more powerful than what you have been used

to until now. Do brake carefully.When you

brake too much with the front brake the rear

wheel may lift off the street and the bike may

tumble over.

If you should hear any unusual sounds while

braking the braking pads might be worn. Do

not use your bike any further until you have

checked the braking pads according to the ma-

nual of the brake manufacturer or ask your lo-

cal dealer.

Your new brake system needs a break-in peri-

od to achieve maximum brake power.This pe-

riod lasts for about 30-40 stops from about 30

km/h, which should be done in a safe area wi-

thout traffic.

Danger! Always make sure that the disc and

brake pads are free of oil and grease. If these

parts are dirty please do not use your bicy-

cle any more.You can clean oily rims or

discs with alcohol or a special spray. Oily

brake pads with oil on them have to be re-

placed. If you are in doubt, please have your

specialist dealer maintain your brake system.

Danger! Disc brakes can overheat on long

down hill rides, fade and fail! On down hill

rides, do not brake constantly, but in several

intervall with higher pressure. If you notice

that the brake power starts to fade, do stop

immediately and let your brakes cool down.

Information for hydraulic rim brakes or disc

brakes

Check before every ride:

G that the brake system does not have any

damages or leaks by activating the lever,

holding it and checking the hose connections

for possible leaks.

Danger! Never touch neither the brake

disc nor the brake caliper after long braking

as this may cause serious injury (risk of

burns).

G that the brake lever pressure is ok by pulling

the lever and ensuring that full braking

performance is achieved before the lever

touches the handlebar. If this is not the case,

pull the lever several times (pump) until it

feels firm.

Gear system

You may only change the gears while you keep

pedaling, smoothly and without applying great

force, all the time that the chain is moving bet-

ween the sprockets. Due to the long cables

that expand under pressure and the housing

that compresses under pressure it may be hel-

pful for changing gears quickly to turn the bar

end shifter a little bit farther than necessary to

select a gear and turn it back to the indexed

position once the chain has properly shifted

("overshift").

Gear system

With the gear system you can adjust the peda-

ling frequency, i.e. means the number of revolu-

tions of the crank per minute, to the terrain

and the desired speed.

Your pedaling frequency should stay between

80-100 revolutions per minute and not fall be-

low 60 while going uphill. If necessary consult

your local dealer and have him retrofit the ge-

ar range to your style of riding.

When the chain length has been propperly ad-

justed you can choose every combination of

front chain rings and rear sprockets to shift

gears. However, it is useful to ride the lowest

gears with the smallest chain ring (the biggest

rear sprocket), the middle gears with the

middle chain ring and the highest (fastest) ge-

ars with the biggest chain ring.

Your Street Machine GT comes standard with

a 27-gear derailleur gear or with a 14-speed

internal hub gear system.The following section

refers to the derailleur gear system only.

Please refer to the manual of the gear manu-

facturer.

You operate the gear changer with the bar

end shifters on the handlebars.

The setup of the chain rings and sprocket le-

ads to an overlap of some gears.This means

that different combinations of chain rings and

sprockets can result in the same gear. It would

be possible to arrange a gear system so that

double gears do not occur but this requires a

lot of concentration when you shift gears whi-

le riding, since you will always have to change

the rear sprockets as well as the front chain

rings. If you would like to change the setup of

your gears please consult your local dealer.

The right lever for the rear derailleur has an

index derailleur system that positions the

chain always on the chosen sprocket, so that

you don't have to "search" for the gears.

It is not possible to index the left lever so that

you have to adjust the front derailleur while

shifting by slightly moving the shifter to stop

the front derailleur from dragging against the

chain while pedaling.

Riding a recumbent requires foresighted gear

shifting. Before stopping you should timely

change in a low gear to make it easy to start

off again, without having to pedal heavily and

struggling with your balance.

Danger! Do practice shifting gears on a

traffic-free street. In the course of this make

yourself familiar with the functioning of the

bar end shifters. Doing this in traffic could

distract your attention from possible dan-

gers.

Light system

If you want to ride your bike on public streets,

it must be equipped with a legal light system.

Do not only use your lights in the dark but al-

so in the twilight of dusk and dawn. Due to

laws and regulations the brightness of bicycle

lights may be considerably lower than that of

other vehicles.Therefore always keep in mind

that other road-users may only see you very

late or not at all.

red button

pressure

adjuster

You switch on the tire dynamo by pressing the red button.To

switch off the dynamo move it away from the wheel.

For the Street Machine Gt, HPVELOTECHNIK of-

fers two different dynamo light systems: one

with a tire dynamo and the other with a hub

generator.

Danger! Do not try to operate the dynamo

lever while riding, your hands could be

caught in the wheel and be injured! To turn

the light system on or off stop riding, dis-

mount your bicycle and only then do turn

the dynamo lever.Turn the lever carefully wi-

thout applying force else you might bend the

lever and damage the plastic parts of the dy-

namo.

Both light systems come with a strong halogen

headlamp and a LED rear light.The LEDs in

the rear light last considerably longer (approx.

100.000 working hours) than a light bulb. For

your safety the light system has a standlight

system at the front and at the rear light, which

makes the LEDs shine on approximately 10

minutes after you have stopped riding.The

electronic system is maintenance free. Because

of the capacitors used you don't have to wor-

ry about batteries.

You can adjust the pressure of the dynamo

against the wheel with the turning knob at the

side.The pressure is right when the dynamo

wheel just does not slip at the wheel, if the

light flickers, the pressure is too low and you

have to increase it.The position of the dynamo

should be so that the extension of the dynamo

axle points through the center of the wheel.

Take care that the dynamo is mounted safely

and does not turn.Worn dynamo wheels can

be exchanged. Please ask your specialist dealer.

The light bulb in your front light can be des-

troyed by wear.Always carry a spare bulb with

you.Take care not to touch the bulb with your

bare fingers, always use a soft cloth.Touching

the glass of the light bulb with bare fingers will

reduce the lifetime of the light bulb.

Tire dynamo

You turn on the light system with the tire dy-

namo at the rear wheel by unlocking the swi-

veling dynamo. For this purpose you press the

red button at the dynamo until it moves to-

wards the rear wheel.To turn the light off, you

turn the dynamo by hand back to its initial po-

sition.

Light system, Prop stand

Hub generator

Prop stand

The light system with a hub generator is swit-

ched on electrically. For this purpose you will

find a switch on the back of the rear light with

three labeled switch positions.With the switch

you can turn the lighting system ON, OFF or

set it to SENSOR. In the SENSOR position a

twilight sensor in the lamp turns the lighting

system on and off automatically depending on

the brightness of the environment.

Danger! Before every ride check whether

the prop stand is lifted up to its riding posi-

tion.With a recumbent prop stands are of-

ten forgotten. In the first left turn the prop

stand can touch the ground and cause a fall!

After a fall you will have to check the prop

stand and the area where it is mounted for

damage and deformation.

For the Street Machine GT you can use a rear

prop stand at the frame or a prop stand that

comes with the optional lowrider.

You get maximum effect with the prop stand

at the lowrider. It supports the bicycle in the

middle of the bike between the wheels.

In case no lowrider is mounted to your bicycle

you can support it with a special rear prop

stand.

You switch on the hub generator light system with the integrated

switch at the front light.

The rear prop stand is mounted at the axle,

put on the quick release axle and supports it-

self at the frame.There has to be a washer

between prop stand and drop out, otherwise

the prop stand is not mounted safely due to

the special shape of the drop out.

The SON hub generator is highly efficient and

works silently.When the dynamo is turned off

it has a very low turning resistance.Although

you can feel the single poles of the used per-

manent magnets very distinctly when turning it

by hand the real rolling resistance is minute.

(The loss is at 15 km/h under 1 Watt).

From spring 2002 on the rear swing arm co-

mes with a welded plate for the PLETSCHER

prop stand.The screws have to be free of gre-

ase, mounted with Loctite and tightened with

8-10 Nm.

Maintenance and care, Brakes

Maintenance and care

Brakes

Your Street Machine GT is fitted with the la-

test bicycle technology that does not require

much maintenance.

The brake pads suffer from wear due to fric-

tion and have to be exchanged then.

The brake pads of your rim brakes are worn

when you can pull the lever further and furt-

However, you will have to maintain your bicy-

cle regularly, as it is with other vehicles too.At her to the handlebar before the pads touch

least once a year the bicycle has to be taken

to a bicycle mechanic for an overall service.

Only this way a long lasting and safe function

of all parts of your bicycle can be guaranteed.

It maintains the value of your bicycle as well as

the fun and the safety while riding for many

years.

the rim.When they are so worn that you can't

see the cross grooves of the pad anymore you

will have your bicycle mechanic exchange the

brake pads.

Also the rim walls suffer from wear.When the

rims are too worn the tire pressure can tear

up the rim and damage the wheel - danger!

Please have your bicycle mechanic check your

rims at the latest after the second brake pad

change and exchange them if necessary.

Read in this chapter how you can carry out

smaller maintenance and care works between

the services.

For a quick overview of the works to be done V-brakes with cables

take a look at the warranty pass on page 58.

To balance the wear of the brake pads you can

tighten the cable with the knurled nut where

the cable goes into the brake lever. First loo-

sen the locknut, then undo the screw so far

that the wheel turns, barely not touching the

pads, hold the screw and tighten the locknut

again towards the brake lever.

Caution! The maintenance works of this re-

cumbent partly require special tools and

skills. Do only work within your limits and,

in the interests of your own safety, do not

go beyond. Should you be uncertain at any

point, get in contact with your local dealer.

Caution! Damaged cables where single

wires stick out have to be exchanged im-

mediately. Otherwise your brake system

may fail - danger! Please take care that the

cable ends are always protected with a cap.

Wear andTear

Like every other vehicle the bicycle has parts

that suffer from wear and tear.The life span of

these parts depends on how often and how

they are used, as well as how they are cared

for. Please note that the wear and tear of cer-

tain parts of the bicycle is perfectly normal

and not a reason for complaint.This manual

contains information about the most frequent

wearing parts.

Brakes

Hydraulic brakes

Hydraulic disc brakes

MAGURA hydraulic brakes use low viscosity mi-

neral oil that, contrary to DOT brake liquid

used in cars, does not absorb water.Thus, you

don't have to change the oil. Please read the

MAGURA manual that comes with the bike.You

will find more detailed maintenance instruc-

tions in the manual "Workshop" that is availa-

ble for download from MAGURA at www.magu-

ra.com. In case of a damaged hose or any lea-

kage of oil always consult a qualified technician

in a bike shop.

MAGURA Clara disc brakes model 2001 or later

feature a fully automatic pad wear adjustment.

Brake pads are subject to wear, therefore re-

gularly check the thickness of your brake pads

and replace them, if necessary.

Caution! Never activate the lever blade wi-

thout the brake pads in place and with the

wheel dismounted.When you transport the

bicycle without wheels always use the trans-

port clips delivered with your bike or put a

piece of cardboard in the brake caliper to

replace the disc. Carefully separate brake

pads that have moved together with a

screwdriver.

Danger! All maintenance work on the hy-

draulic system of your brakes may only be

carried out by a qualified technician. In case

these works are carried out without the re-

quired knowledge and skills the brake

system might fail which can lead to a serious

crash.

The brake caliper is bolted to the frame with

M6 screws, tightening torque is 6 Nm.To

achieve the perfect alignment of brake caliper

and rotor, tiny washers of 0,2 mm thickness

can be added between brake caliper and frame

fittings.

Hydraulic rim brakes

To balance the wear of the brake pads there is

a turning knob at the brake lever.Turn this

knob anti clockwise to move the pads closer

to the rim.As soon as the knob doesn't turn

anymore the brake pads have to be exchanged.

Before you change the pads turn the knob

clockwise as far as it will go, back to the initial

position.

Gear system

Gear System

Danger! If the bike falls over, the derailleur

or its mounting can be bent so that the mo-

vement of the derailleur changes. Check the

movement and have it readjusted by your bi-

cycle mechanic, if necessary.

Please read the manual of the gear system ma-

nufacturer carefully when you want to work

on it.

Your dealer will have carefully adjusted your

derailleur gearing system before handing over

the bike. But during the first 100 kilometers of

riding the gear cables can stretch, making the

gear indexing imprecise.The chain then climbs

only hesitantly onto the next sprocket.

All moving parts of the gear system are affec-

ted by wear. Cleaning and lubricating these

parts frequently can prolong the life of these

parts, however they will have to be replaced

once worn out.

Adjusting the gear indexing for the rear

derailleur

Adjust the barrel adjuster where the gear ca-

ble goes into the rear derailleur. Do it in small

steps of half a turn.

The cables have to be checked, cleaned and

serviced regularly. Expect more wear and cor-

rosion when the bike is often parked outside

in bad weather conditions.

Check after each adjustment whether the

chain moves smoothly up to the next larger

sprocket.To do this, either turn the cranks by

hand or ride the bike.

Caution! Damaged cables that show for

example single wires have to be changed

immediately. Otherwise they may damage

your gear system.Take care that the ends

of the cables are protected with fitting

caps.

When the chain climbs up easily, you need to

check that it still goes down easily onto the

smallest sprocket. If necessary turn the barrel

adjuster a little more and then try shifting ge-

ars again.

Danger! If the chain shifts over the smallest

or the biggest sprocket you have to readjust

the end-limit adjusters of the rear or the

front derailleur. Incorrect adjustment can le-

ad to the chain coming off, getting stuck or

damaging the spokes, which may result in se-

rious falls.The adjustment of the end-limit

adjusters is a job for the professional cycle

mechanic.

Chain

Danger! Take care not to pour any oil on

the rims, brake discs or the tires.The brake

system could fail or the tires could slip away

suddenly.The oil affects the rubber of your

tires and could damage them.While lubrica-

ting cover the surrounding area with an old

newspaper.

The chain is a wearing part that has to be lu-

bricated regularly and to be changed at signs

of excessive wear and tear.

Lubricating the chain

Diligent lubrication is important.The chain of

your Street Machine GT is approximately 2.5

times longer than a standard bicycle chain (ap-

prox. 3.8 m). But it also lasts longer since a

chain only wears while bending at the sprok-

kets and the chain rings.

An effective protection against corrosion is

critical for a long chain life. Some minutes after

you have oiled the chain rub it with a cloth to

remove superfluous oil from the outer surface.

Wax the chain thoroughly with a wax spray.

The wax keeps off water, protects from corro-

sion and makes dirt fall off easily.

Use a good chain oil that won't leave a sticky

film on the chain.The chain oil may not con-

tain any aggressive chemical substances that

might affect the surface of the chain tube.

If the chain has become wet after riding in the

rain you should put your bicycle in a dry and

heated room, and every day you should turn

the crank and so move the chain until it is dry

again. Otherwise it is difficult for the moisture

in the tubes to evaporate which may lead to

corrosion at the chain.

Specialist stores sell biodegradable lubricants.

HPVELOTECHNIK solely recommends

PROFIDRYLUBE.This lubricant is purely based on

PTFE (Teflon) that keeps the chain clean and

dry.This way dirt simply falls off and the tubes

(also made of Teflon) always stay clean.Your

dealer can obtain it from HPVELOTECHNIK.

It is important that you clean the chain with an

oily cloth before lubricating. Otherwise the

fresh oil washes the dirt that clings to the

chain into the gaps and the bushings where the

dirt causes heavy wear.

Do not use any solvents to clean the chain!

The solvent washes the oil off the bearing

parts, stays there and dilutes the fresh oil so

that a sufficient lubrication is not guaranteed. If

you have treated the chain with a solvent you

will have to heat it up with a hot air torch or

boil it in chain grease.

kets and chain rings anymore and wear them

away very quickly.

front and the big rear sprocket.The derailleur

must be able to compensate a tightening of

the chain by 4 cm. Please see also the manual

of the derailleur manufacturer on the choice

of the correct chain length.

Check the chain regularly for lengthening. For

this purpose try to remove the chain from the

chain ring.The chain may come off to a maxi-

mum of 5 mm. For a more precise reading you

can buy a chain measurement gauge in your bi-

ke shop that you simply put into the chain.

Caution! The chain has to be closed with a

special joining link or a chain riveting tool

that expands the ends of the rivet while ri-

veting (ROHLOFF revolver).A poorly joined

chain may break, you can come off the pe-

dals and fall. If you are in doubt please have

adjustments of the chain length or the chan-

ging of the chain be done by your bicycle

mechanic.

Only use chains that are suitable for the gear

system of your bike. Otherwise a precise gear

shifting is not guaranteed any more. Please

consult your dealer on this topic. He will also

assist you in checking your sprockets and chain

rings.A new chain does not fit a worn sprok-

ket or chain ring.We recommend chains from

SRAM with smoothly rounded edges.They also

shift gears very well.

See that the joining link is not bigger in size

than the other chain links to avoid irregular

chain sounds.We recommend the joining links

by SRAM (power links). Every time you change

the chain you also have to mount a new po-

wer link.

Caution! When you change the chain take

care that the new chain does not show any

sharp edges or burrs.Very thin racing chains

are also not suitable since they wear the

chain tubes and the chain roller much faster.

HPVELOTECHNIK delivers spare chains by the

meter via your dealer. For this purpose please

indicate the exact length of your chain or or-

der it a little bit longer if you want to be sure

it fits.You will need approx. 3,8 m of chain.

ChainTubes

Expanding the tube ends

Chain tubes

The ends of the tubes are expanded like a

trumpet so that the chain can enter smoothly

without friction and without making noises.

The chain protection tubes consist of Teflon, a

long lasting plastic, that features very low fric-

tion, slow wear and good noise damping.The

tubes protect your clothes against the chain oil

as well as the chain against dirt from the road.

When the ends are worn out you can renew

them through expansion. Remove the chain by

opening the power link or open it with a spe-

cial chain riveting tool. Cut the worn part of

the tube exactly perpendicular with a sharp

knife.

The upper tubes are fastened with an inter-

changeable retention spring, the lower tube

runs through an adjustable clip.

The tubes are worn by the chain and have to

be cut at the ends and expanded again (or ex-

changed) after 3.000-5.000 km approximately,

depending on how many kilometers have been

ridden, on the chain type and the overall riding

condition.You can extend this maintenance

interval by turning the tubes by a quarter turn

from time to time so that they do not keep

wearing out in the same place.

Heat the last 5-10 mm at the end of the tube

with a gas burner or a candle and turn it per-

manently until the color of the utmost edge

turns from a dull black to a shiny black. Now

you expand the end with a proper tool, e.g.

the rounded grip of a screwdriver. Quench the

expanded end immediately with cold water.

Take care that the tubes don't catch fire since

burning Teflon develops toxic vapors.At any

rate, work in a place with sufficient ventilation.

The intensity of the wear depends mainly on

the chain type. Please see also the instructions

on "Chain" on page 36.

If the tube is too short after you have cut it so

that there is not enough protection anymore it

has to be replaced.You can buy spare tubes

either as uncut tubes or already cut into the

correct length, complete with retention spring

from your specialist dealer.

In order to perform any work at the chain tu-

bes you'll have to open the chain and finally

close it again. Please see the instructions on

"Chain" on page 36.

Caution! Take care that the chain tubes

keep at least a 5 cm distance to the rear and

front derailleur when the chain is stretched

to the maximum, and that the tubes are well

fastened. If necessary you will have to shor-

ten the tubes. If the end of a chain tube gets

into the rotating drive train it can be blok-

ked and the chain tubes may be destroyed.

Changing the tubes

Changing the lower chain tube

In order to exchange single parts in the upper

chain tubes cut the old tube at the retention

spring at the chain roller and pull the remai-

ning part off the spring. Now move the

smooth part of the new tube through the

spring and expand the tube end as described

above.

Open the retention clips. On the bottom side

of the clip there is a lid that is put over a

hook.You can lift up the lid with a screwdriver

and expand the clip. Change the lower chain

tube and close the clips by fastening the lids

over the hooks.

Caution! The rear end of the upper chain

tube has to be secured against moving with

a cable tie that is wrapped around the tube

near the retention spring.Without the cable

tie the tube may be dragged forward into

the turning chain guide and thus be damaged

by the chain.

Changing the complete upper chain pro-

tection or the retention spring

Disassemble the chain roller. For this purpose

hold the nut on the left side of the frame with

a ring spanner SW 13 and undo the screw in

the chain roller with an Allen key SW 8.

Remember the exact position of the spacers.

Take the bolt off the frame together with the

chain roller. Between frame and chain roller is

a spacer that is encased in a transparent

plastic tube.

Take the retention spring off this spacer and

put on the new retention spring.Turn the

spring so that the retention springs run under

the spacer to the tubes and the wires lie bet-

ween frame and chain tube; that way the spi-

rals look outwards.

Lubricate the shaft of the retaining bolt. Push

the bolt through the chain roller, the washer,

the chain retention hook and the spacer with

the retention spring into the frame. Put on the

washer on the left side, secure the thread with

Loctite and tighten the nut with 14-16 Nm.

Chain roller

Dismounting the chain roller

The chain roller guides the chain below the se-

at to the rear wheel and is an essential part of

the HPVELOTECHNIK No Squat design. It ensu-

res that no pedaling influences get into the

suspension.

Hold the nut on the left side of the frame with

a ring spanner SW 13 and undo the screw in

the chain roller with an Allen key SW 8.

Memorize the exact position of the washers.

Remove the screw together with the chain

roller from the frame. Change the chain roller.

Lubricate the shaft of the screw..

The surface of the chain roller features a „si-

lent ring“ that is made of a long lasting elasto-

mer. Depending on maintenance and care it

has a life span of approx. 3000-5000 km.When

this section is worn completely the links of the

chain will run on the roller. In that case you

will notice that the chain makes more noise

while running and you should change the rol-

ler.

Push the screw through the chain roller, the

washer and the spacer with the retention

spring into the frame. Put on the washer on

the left side, secure the thread with LOCTITE

and tighten the nut with 14-16 Nm.

The chain roller consists of two parts.After

you have dismounted the chain roller you can

tear the two halves apart and change the silent

ring.

Caution! The roller comes with two main-

tenance free sealed bearings.The bearings

are exchangeable. Between the bearings the-

re is a spacer that keeps the correct distan-

ce. If you forget to put in the spacer after

you have dismounted the bearings they will

be destroyed when you tighten the screw

while remounting them.

The bearings must not be treated with a jet of

water from a high-pressure cleaner or with

solvents since it destroys the seals and remo-

ves grease in the bearings. If the bearings don't

move smoothly anymore you'll have to replace

them.

Suspension Fork

Safety instructions

Suspension fork

Always check the correct position of brakes

and wheels after you have worked on the sus-

pension fork as described in the respective

chapters. Check that the quick releases are

tightly closed.

Clean and grease your suspension fork regu-

larly.

Always use a high quality silicone or Teflon lu-

bricant.You can purchase special lubricants for

suspension forks at your local specialist dealer.

The inner fork steerer tube is tightly fitted and

glued in the fork crown, never try to tear this

connection apart or to change the tube.

If your suspension fork has lubricating nipples

at the back you should insert a small amount

of grease every four weeks.

Never add threads to the steerer tube - danger

of breaking!

After six months at the latest the fork has to

be lubricated again. For that purpose open the

fork and dismount the parts as described in

the following paragraph. If you are in doubt

please have your bicycle mechanic do the

work.

The hydraulic damping cartridge is pressureri-

zed and must not be opened. In case of damage

the whole cartridge has to be replaced.

Caution:After you have removed the adjust-

ment screw (5) you'll see a small hex-headed

screw in the piston rod of the damper: never

undo this screw. It is under pressure. If this

screw is undone too far it can damage the

damper.

If your suspension fork comes with a dust

boot please clean the lower and upper leg and

the seal under the dust boots every four

weeks. Otherwise, dirt and water can lead to

corrosion.

Before every ride check the suspension fork

for signs of damage, deformation or corrosion.

If this is the case don't use your bicycle anymo-

re.Ask your local dealer for service.

Lubricate the legs regularly with a thin film.

The following instructions refer to MEKS

Carbon suspension forks. For other brands

please see the instruction manual that comes

Exchanging springs

Lubricating the fork / Dismounting

In order to lubricate the fork have your bicy-

cle mechanic dismount it completely.

Gently turn the adjustment knob for the pre-

load on the adjustment unit (9) clockwise as

far as it will go.This causes the spring to relax.

First remove the pre-load adjustment unit and

springs as described under "Exchanging

springs".

If your spring has an adjustable damping (MEKS

Carbon AC) turn the knob clockwise as far as

it will go so that the fork does not decom-

presses again.

Undo and remove the screw M6 on the lower

part of the leg (18).To prevent the push rod

(14) from turning too press the fork together

entirely and hold the push-rod with a long

Allen key SW5.

After you have relaxed the pre-load unit of the spring you can

turn off the entire unit.

Place a matching spanner or an adjustable

wrench on the two parallel surfaces of the

pre-load adjustment unit.Then remove the

entire unit by turning it anti-clockwise.

At the suspension fork MEKS Carbon All per-

form the same work on the second spring

strut. Now you can pull the upper part of the

fork out of the lower part.

Carefully remove the springs with one finger

or the head of a spoke from the fork.

Alternately put your bicycle upside down and

catch the springs when they fall down.

At the suspension fork MEKS Carbon AC re-

move the screw on the lower part of the leg

(19). Usually the damping cartridge (3) does

not turn. However, when you have difficulties

in removing the screw you can fix the cartrid-

ge in the upper leg with a screw driver and

thus prevent it from turning too. For this pur-

pose, undo the entire damper adjustment unit

Exchange the springs, lightly grease all parts

and assemble the fork again in reverse order.

After having finished the assembly please check by placing a wrench on the cap (8). Caution:

if the fork works properly by compressing it

several times manually.

Never disassemble the adjustment unit (4, 5, 6,

7, 8)!

Clean all parts with a cloth. Grease the bus-

hings, legs, springs and threads thoroughly and

assemble the fork again.

Suspension Fork

Exchanging the bushings

The bushings of the suspension fork suffer

from wear and tear through normal use. It de-

pends on the use of the fork, the amount of

dirt on it and the lubrication how long it lasts.

If the bushings are worn the fork has too

much play. Please have your specialist dealer

replace the bushings in that case.

Rear suspension element

If there is a safety ring at the thread of the

Rear suspension element

suspension element push it to the front so

that you can undo the adjustment ring comple-

tely and then turn it to the utmost position at

the front. Remove the slotted spring retention

disc at the rear end.

Changing the spring

You can buy the spring for the rear suspension

element in different spring stiffnesses from

your dealer.

We recommend the following spring stiffnes-

ses, depending on the overall weight:

Danger! If the bicycle does not stand on

the ground while undoing the screws of the

suspension element the rear swing arm may

come down uncontrolled afterwards and

hurt you seriously. In addition to this the ca-

bles of the gear system and the brakes may

overstretch and you would have to replace

them. Ensure that the rear swing arm comes

down in a controlled and gentle fashion by

putting up a solid string or cable tie bet-

ween the main frame and the rear swing

arm.

up to 80 kg (183 lbs): 350 lbs./inch

up to 100 kg (230 lbs): 450 lbs./inch

up to 120 kg (275 lbs): 550 lbs./inch

In addition to this your dealer can also use

springs with other spring stiffnesses or special

lightweight springs made of titanium.

In most cases the stiffness is printed onto the

spring.Take care to read the imprint carefully,

since the term "B650" that sometimes occurs

does not mean 650 lbs./inch!

Spring lengths:

DV22: 83 mm (70-90 mm)

ST8ARC: 70 mm (65-76 mm)

Danger! When the bicycle is standing on

the ground the frame and the swing arm co-

me up against each other. Please make sure

that this happens in a controlled and gentle

fashion. Put a cloth between the contact po-

ints. Otherwise, if they come up against each

other uncontrolled your hands may get

caught between main frame, rear arm swing

and suspension element and your bicycle

may be damaged.

In order to change the spring you will have to

remove the rear screw and swing away the re-

ar frame.

Hold the main frame of your bicycle in a work

stand.

In case you have a suspension element with

adjustable damping first remove the rear ad-

justment knob for the damping control by un-

doing the small screw at the side with an Allen

key and by then pulling of the knob.

Undo the screws of the rear suspension ele-

ment with two Allen keys and push the screw

out of the suspension element eye.

Rear Suspension Element

Move the rear swing arm down carefully. In

doing this, take care that you don't bend or

stretch any cables.

Cleaning and lubricating

Do clean the suspension element, especially

the polished piston rod, if it is dirty. Remaining

dirt and sand can damage the seals of the hy-

draulic system and so shorten its life consider-

Remove the spring from the suspension ele-

ment and put in the exchange spring. Make su- ably.When you often use dirty roads you can

re that the new spring has the same diameter

and length as the old spring and that it lies sa-

fely on the adjustment ring.

protect the suspension element from dirt with

an elastic cover that you can buy at your local

dealer.

Put back the slotted rear spring retention disc

on the piston rod. If necessary, compress the

spring a little bit with a screw driver.The

spring retention disc has to match its seating

at the rear end of the suspension element.

From time to time grease the thread for the

spring pre-load with a drop of acid-free oil.

Thus, you can always turn the adjustment ring

easily by hand. Once a year you have to grease

the pivots of the suspension element. For that

purpose dismount the suspension element as

Secure the spring by tightening the adjustment described under "Changing the Spring" on pa-

ring until the spring doesn't have any play any-

more. If there is a safety ring, push it back into

Secure the screws of the suspension element

with LOCTITE and tighten the screw with 6-8

Nm.

In case you have a suspension element with

adjustable damping put back the adjustment

knob on the small rod, turn it so that the

screw fits exactly and noticeably to the flat

part of the rod and tighten the screw again.

The bushings of the rear spring element need to be lubricated

once a year.

After having exchanged the spring you have to

readjust the spring pre-load as described in

the chapter on "Adjusting your new bicycle"

on page 18.

Swing arm pivot

The bushings are exchangeable. For that pur-

pose you will have to dismount the rear swing

arm and send it together with the axle via

your specialist dealer to HPVELOTECHNIK.After

having been mounted the bushings are machi-

ned to adjust them.

Swing arm pivot

The rear swing arm pivot comes with mainte-

nance free bushings.They have a self lubricating

system with Teflon particles.The bushings

sustain a very high load and they show almost

no wear.

Undoing the axle screws

In case you notice play or a creaking noise at

the rear swing arm please check the two

screws that keep the axle in the frame.They

will have to be secured with LOCTITE.

In order to mount the rear rack or the lowri-

der the axle screws have to be undone.We re-

commend you to leave one screw in place to

prevent the axle from turning.

Tightening torques:

Mushroom head screw M8x25 (without rear

rack): 14-16 Nm

In case the rear swing arm is to be dismoun-

ted completely you can prevent the axle from

turning by inserting a thin metal rod in the ho-

le of the axle through the drilling of the rear

swing arm under the axle.

Screw M8x45: 17-19 Nm

Danger! If the screws at the axle are not

tight enough this leads to play and noises

when the spring compresses. In extreme ca-

ses the swing arm may come loose which le-

ads to a serious fall. If the screws are too

tight the thread of the axle may tear out or

the screw may be damaged.

Caution! There has to be a big washer bet-

ween the main frame and the end of the

bushing else the busing is not able to func-

tion without play and the frame will be da-

maged.

You can prevent the axle from turning by inserting a thin metal

rod in the hole of the axle.

Seat

For transport purposes you can dismount the

seat. For that purpose open the quick releases

and unscrew the knurled nuts from the axle.

Then remove the quick releases and catch the

washers that come out too.To remount the

seat, do all the steps in reverse order.

Interchanging the seats

In principle you can interchange the different

seat sizes and the seats of the Street Machine

Gt with the Speedmachine.

If the adjusting range of 10° cannot fully be

used after you have exchanged the seat you

will have to slightly reposition the slotted alu-

minum fittings at the seat.

For that purpose, take off the seat cushion.

Undo the self-locking nuts of each of the 4

screws of the upper and lower seat fastening

by several turns.The holes in the aluminum fit-

tings are slightly bigger than the diameter of

the screws so that you can move the alumi-

num fittings up or down to find the biggest ad-

justing range possible.

Finally tighten all screws of the seat fastening

by 8-10 Nm.

Screws that are not tight enough may lead to

cracking noises while riding and may damage

the seat.

Seat Cushion

For better ventilation, an airflow cushion is

available as accessory.This cushion consists of

several layers:A soft foam and a rigid mesh,

which provides for an approximately 1 cm

thick air cushion with excellent circulation.

These two layers are wrapped up in a cover

that consists of fine mesh like it is known from

high quality Rucksacks.

Seat cushion

The standard seat cushion consists of a 1,4 cm

thick layer of flexible EVA foam.This is a black

material with closed cells that is also used in

the production of high quality camping mats. It

feels very comfortable without appearing too

soft or spongy. It is waterproof so that you can

dry your seat with a sweep of your hand in ca-

se your bicycle has become wet.

You can wash the material at 30° Celcius and

it dries very quickly. In case you want to wash

the seat cushion take it off the seat.Then open

theVelcro at the back and take out the foam

cushion and the airflow insert.

Caution! The seat cushion is fastened with

Velcro and you can take it off. For this pur-

pose it is important not to simply grab the

foam and take it off since theVelcro could

come off. In order to take off the seat cus-

hion lift up the upper part a little bit from

the seat.Then you grab the cushion on both

sides together with the end of theVelcro

that sticks out slightly and remove the cus-

hion slowly. In case theVelcro comes off

fasten it again with a good glue.

The seat cushion suffers from wear through

constant use.At the parts that are under punc-

tual strain the mesh can be pressed together

permanently. In order to provide a good riding

comfort in that situation the airflow cushion

has additional foam padding.

Caution! Never expose the seat cushion to

extreme heat or focused sunlight.The mate-

rial warms up considerably.The heat may

melt the glue of theVelcro.The seat cushion

can be damaged when the rays of the sun

are bundled through a lens.Take care to ne-

ver leave any bubble wrap on the seat in the

sun.The air bubbles in the film act like a

burning glass and shrink the seat cushion.

Water bottle Cage, Mudguards

Another useful alternative to water bottles are

Water bottle cage

systems with a "water bag" and a drinking ho-

se, e.g. from SOURCE or CAMELBAG.You can sim-

ply strap them behind the seat, onto the rear

rack or into the Speedbag.

You can mount a water bottle cage at the side

of the seat, under the frame between the

wheels or at the front derailleur tube.The

main frame tube and the derailleur tube at the

front of the frame come already with threa-

ding inserts M5 for that purpose.

Mudguards

At bicycles with suspension mudguards are ex-

posed to very strong vibrations through which

they may break. Please check the stays of the

mudguard regularly for their position and

check the mudguards for cracks or deforma-

tions. Immediately replace damaged mud-

guards.

You can mount a water bottle cage at the left

or right side of the seat so that you can com-

fortably reach it while riding. For that purpose

you can drill two holes into the outmost edge

of the seat.To fasten the cage use screws with

big heads or big washers in order not do da-

mage the fiberglass of the seat.Another good

alternative is the position at the back of the

seat between the shoulders where you can al-

so comfortably grab the bottle while riding.

Caution!You must not mount additional

parts like rear lights or reflectors to the

mudguards since those may break then.

In order to prevent falls you have to fasten the

stays of the front mudguard with a security

clip that opens under pressure.When the clip

has opened once please replace it with a new

one.

Danger! If branches or other obstacles get

caught in the wheels while riding and are

moved around they may drag the mudguards

along.The mudguard can possibly fold up

between frame and tire and hence block the

wheel, which may lead to a serious fall. If you

hear any unknown noises while riding stop

immediately and remove anything that might

cling to the mudguards or the wheels.

An ideal position for water bottle cages is at the side of the seat.

Caution! Do not drill any holes into other

seat areas than those indicated above. It is

especially important not to damage the rein-

forcing ribs.

Mudguards,Wheels

Alternatively you can mount the stays at the

two outer screws of the U-brace or fasten it

with a clip in the middle of the lower leg of

the suspension fork.

After you have performed service work or re-

placed mudguards check if the wheels turn

freely. Between mudguard and wheel has to be

a distance of at least 7 mm.

Check whether the suspension can still fully

compress with themounted mudguards.The

mudguards, stays and screws (especially at the

U-brace of the suspension fork) must not

touch other parts under maximum compres-

sion.

Before pumping up the tire, you have to undo the little knurled

nut on the valve.

Now you see a small threaded rod with a

knurled nut that comes out of the valve. Undo

the knurled nut by loosening it as far as it

goes.

Wheels

To pump up the tire and check the pressure

you need a pump with a gauge, preferably a so-

lid standing air pump. Put the knob of the

pump on the valve, push it completely on the

valve and then retract it a little bit. Now you

can pump up your tire easily.

The correct air pressure is decisive for

smooth running and a good protection against

punctures.The maximum pressure is printed

on the side of your tire. Since your Street

Machine GT is fully suspended you can always

go for the maximum pressure.You might find

an indication of the minimum required pressu-

re on the side of the tire as well.

After you have pumped up the tire to the ma-

ximum pressure pull off the pump knob.

Secure the valve through turning the knurled

nut on the threaded rod as far as it will go to-

wards the valve. Finally put on the valve cap

again.

Since the tubes in the tires gradually loose air

you should check the air pressure before eve-

ry ride.

The tubes come with Presta valves (also called

french valves).They are very airtight and easy

to pump up. For that purpose first undo the

valve cap.

Danger! Never pump up your tires beyond

the maximum pressure.The tire may burst

while riding or come off the rim, which may

result in a serious fall.

Wheels, Cleaning and conservation

Danger! Check your tires for damage on a

regular basis.You should exchange tires with

worn threads or damaged sidewalls.

Damaged rim tapes have to be exchanged

immediately. Damages at the tires may lead

to a sudden burst of the tire and thus result

in a serious fall.

Caution! To true up the wheels you need

special skills, please have this work done by

an experienced bicycle mechanic.

The wheels are fastened with a quick release

lever and therefore they are susceptible to

theft. For this reason always lock the wheels

along with the frame to a solid object when

you park your bicycle somewhere. It is also

possible to exchange the quick release axles

with axles that have special security locks (e.g.

PITLOCK or KRYPTONITE) that can only be ope-

ned with a special tool.

When you exchange tires please note the ma-

ximum width limit of 50 mm (approx. 2 ").We

recommend tires that are 32-40 mm wide.At

the front wheel you have to use tires of ISO

size 406 (20"), at the rear wheel ISO size 559

(26").The tire width possible at your bicycle

depends on the size of your rims. Please ask

your local dealer.

Cleaning and conservation

The frame of the Street Machine GT has a

high quality and environmentally friendly pow-

der coating.The surfaces of the aluminum

parts are either polished or anodized.

After you have exchanged the tires please

check if the wheels turn freely and check the

minimum distance between mudguards and

frame.

To keep the surfaces brilliant over many years

and to protect them effectively against corro-

sion the bicycle has to be cleaned from dirt

and then conserved.

The spokes of the wheels connect the rim

with the hub.With disc brakes and at the rear

wheel they additionally transmit the braking

power and the pedal forces.

Dried sweat but also environmental influences

such as air pollution, dirt on the roads and es-

pecially grit affect the parts, and not only do

they result in visual faults but also in serious

structural damage of the parts through corro-

sion.

Danger! Take care that your spokes are al-

ways in perfect condition and the spoke ten-

sion is balanced. Do not ride with wheels

that run untrue or wheels with loose or

missing spokes.These faults may lead to a

total failure of the wheel while braking and

result in a serious fall!

In contrast to a widespread belief particularly

the "non-rusting" aluminum is dramatically af-

fected by grit! This kind of damage may not be

visible in the beginning but it leads to a serious

danger when the part breaks.

Do clean and conserve your bicycle diligently!

In case of small scratches at the surface of the

powder coating of the frame or the surface of

the seat or the Speedbag you can simply polish

them away.You can buy a special polishing

The best things to clean your bicycle with are

warm water and a soft cloth. If your bicycle is

very dirty first take a wet sponge to soften the agent for epoxy resins at a specialist dealer for

dirt and then remove it. In case of bad grease

or oil stains you should use a special cleansing

agent for bicycles in addition.

boat building. Do not use a polish for metal!

After you have cleaned the bicycle, dry it and

treat the paintwork and the metal surfaces

with wax.You can purchase this wax from your

local bike dealer as a convenient spray.

Caution! Do not use any cleansing agents

that scrub or are chemically aggressive since

they affect the paintwork. Before using any

cleansing agent please test it at a part of

your bicycle that is not immediately visible.

The wax passes moisture and flows into tiny

gaps and pores.After some minutes the sol-

vent evaporates and leaves a dull and glutinous

film. Now polish the waxed parts of your bicy-

cle with a soft cloth to make it real shiny.

Caution! Do not use any high-pressure cle-

aner.The strong jet of water goes through

the seals of the bearings, blows away the lu-

be and causes corrosion of the bearing parts

and the chain. In addition to this it may da-

mage stickers.

Do not only wax the frame but also the spo-

kes, hubs, screws and nuts etc.You can also

conserve the chain with wax spray after lubri-

cating it, see also the chapter on "Chain", page

36.

holes.Therefore protect the inside of your fra-

me by applying wax spray through the holes.

Caution! Any damage of the paintwork has

to be cleaned from rust and repaired imme-

diately, else the damaged part in the frame

gives way to corrosion that nests in the sur-

rounding paintwork.This can result in dama-

ge of the frame.

Protect the parts where cables or chain tubes

may scratch the frame with a layer of tape.You

can buy extra strong transparent tape at your

do-it-yourself-store.That way you avoid scrat-

ches in the powder coating and coating co-

ming off.

Storing the bicycle, Screws and bolts

Do use high quality acid free grease, if possible

Storing the bicycle

a lubricant with added solid particles like

Teflon or MoS².Their ingredients still work

properly after the thinner grease has been re-

moved from the contact points.

Before you are going to store your bicycle

over a longer period of time, e.g. over winter,

please take care of the following steps:

G Clean your bicycle and protect it from

corrosion as described in the chapter on

"Cleaning".

G Store your bicycle in a dry and warm place.

G Avoid direct sun and storage close to the

heating since it affects the rubber of your

tires.

G Choose the smallest sprocket and the

smallest chain ring.That way the cables are

in the most relaxed position.

G The tubes of your tires loose air when

standing over a longer period of time. If the

bicycle then rests on flat tires the tires may

be damaged.Therefore hang up your bicycle

or check the air pressure regularly.

Alternatively you can use LOCTITE screw secu-

ring fluid that you apply to the screw before

you put it into the thread.

Always check the screws very diligently for

signs of corrosion. Rust at the screw heads

may also lead to the screw seizing in the thre-

ad.When the metallic and shiny coating of gal-

vanized screws comes off and discloses dull,

gray-brown steel you have to exchange the

screw.

When you exchange screws please do only

use screws of the same type. Screws come in

different strength classes. Please do only use

galvanized screws of the same type and

strength, corresponding to the German

strength classes 8.8 or stainless steel screws

grade A2, when not given any other recom-

mendation. If you are in doubt please ask your

specialist dealer.

The winter months are a convenient period of

time for the annual service since then you wo-

n't have to wait long for an appointment. Many

dealers offer special prices for the winter

check.

Screws and Bolts

Screws gradually settle in and through this

they can come loose.Therefore check the

screws and bolts regularly if they are tightened

appropriately with a torque wrench.

In the following table you will find the prescri-

bed tightening torques, they refer to greased

screws!

The grease also prevents your screws from

seizing in their threads so that they won't un-

screw anymore. In particular, screws made of

stainless steel are susceptible to this and the-

refore have always to be put in with grease.

You can avoid seasonal waiting periods in

spring and summer when you have your annual

inspection done in the quiet months from

October to January. Many bike shops then ha-

ve special winter check offers.At any rate do

make an appointment. Clean your bicycle prior

to the inspection since then many of the

checks by sight can be done quickly and at low

cost.

I have received the bicycle in good condition. I ha-

ve been informed about the correct use of the

recumbent, the components like derailleur and es-

pecially steering and brakes as well as the necessi-

ty of regular service and maintenance. I will read

the manuals prior to the first ride and have all fu-

ture users read them too.

Date:

Please have your specialist dealer record every

inspection and service work in the Warranty

Pass.This is a requirement for the validity of

our extended warranty that exceeds the legal

warranty.

note

The service intervals given in this Warranty

Pass refer to an average use and a riding per-

formance of 3.000 km per year.

The regular service maintains the safe opera-

tion and the value of your bicycle. Not only

does the completed Warranty Pass record the

maintenance works for the validation of your

warranty but also does it proove the care and

the value of your bicycle - a good thing to

have when you are going to sell your Street

Machine Gt one day.

When you ride more kilometers per year or

often ride under bad conditions like rain, grit

or other dirty factors it is necessary to have

shorter maintenance intervals.

In order to measure your riding performance

we recommend you to use a bicycle computer.
