4 Safety information
4.1 Basic safety information
Please read all the warnings and information in this User
Manual carelly before using the bike. Keep this User
Manual near your bike for ready reference.
If you hand this bike over to someone else, don't forget to
give them the User Manual as well.
4.2 For your own safety
iAlways use a suitable bicycle helmet and wear it
correctly.
iWear bright clothing or reective elements so
that other road users can see you in good time.
iWear shoes with a sti, and whenever possible,
non-slip sole.
iWear close-tting clothing on your legs, or wear
trouser clips.
iWear protective clothing such as robust shoes
and gloves.
4.3 Information for parents and legal
guardians
iMake sure that your child has been taught, and
also understands, how to handle the bike safely
and responsibly in the environment in which it is
going to be used.
iExplain to your child how to operate all the
brakes, and also how they work and any special
features. For rther important information on
this matter, refer to ¯Chapter 21 "Brake, brake
levers and brake systems".
iAs the legal guardian, you are responsible for the
safety of your child and any damage he/she may
cause when cycling. You should therefore make
absolutely sure that the bike is in technically
sound condition and adjust it regularly to the
size of the child.
4.4 Safety in road trac
iObserve the applicable trac regulations.
iNever ride with no hands!
iIn some countries children below a certain age
must ride on the pavement and must also dis-
mount when crossing the road. Please familiarise
yourself with the applicable regulations.
iAdjust your handling on wet or slippery roads;
ride more slowly and brake carelly and in good
time as you will require a much greater braking
distance.
iAdopt a speed that reects the terrain as well as
your riding ability.
iDo not listen to music through headphones when
cycling.
iDo not cycle when using a mobile phone.
iUse designated cycle paths when not using pub-
lic roads.

8 I General User Manual
iBe ready to brake, especially if you are not sure
what lies ahead or are riding downhill.
4.5 Bike safety
iOnly bikes that have been approved for use in
public places, as per the applicable regulations
(e.g. StVZO in Germany), may be used.
iObserve the maximum permitted gross weight of
the various bike types, as this could otherwise
lead to breakage or failure of safety-relevant
components. The brake system is also only de-
signed for the maximum permitted gross weight
of the bike. For a list of the maximum permitted
gross weights, refer to ¯Chapter 30 "Technical
data".
The gross weight is the sum of the weight
of the bike + weight of the rider + weight of the
luggage. The gross weight also includes towed
weights such as trailers.
iIf you notice that a part is damaged or warped,
do not use the bike until you have had the part
replaced as otherwise parts that are important to
operation of the bike may fail.
iObserve the maximum load-carrying capacity of
the pannier rack. This is marked on the pannier
rack directly (also refer to ¯Chapter 30 "Techni-
cal data").
iHave maintenance and repairs carried out by a
professional bike workshop (for maintenance
intervals, refer to ¯Chapter 28 "Regular inspec-
tions").
iIf you make technical changes to your bike, take
the national trac regulations and applicable
standards into account. Bear in mind that this
could render your warranty invalid.
iOnly replace electrical components on your bike
with type-tested parts.
iOnly ride with suitable lighting in unfavourable
lighting conditions such as fog, rain, dawn/twi-
light or in the dark.
Bear in mind that with intensive use of your bike wear
increases accordingly. Many bike parts, particularly
on light sports bikes, are only designed for a specic
period of use. If this is exceeded, there is a consider-
able risk that components could fail.
Perform care and maintenance on your bike regularly.
In doing so, check important components, particularly
the ame, fork, wheel suspension, handlebar, handle-
bar stem, seatpost and brakes for warping and dam-
age. If you notice changes such as cracks, bulges or
warping, have your bike checked by a specialist cycle
shop before using again.
5 Legal provisions
If you wish to use your bike in road trac, make sure that
your bike complies with the road trac regulations. If
necessary, observe ¯Chapter 22.2 "Special regulations for
road bikes".
5.1 Applicable road trac licensing
regulations
Before you take your bike on the road, nd out what the
relevant national regulations in your country are – in
Germany, these are the Road Trac Licensing Regulations
(StVZO) and the Road Trac Ordinance (StVO).
In Switzerland, the applicable regulations can be found
in the Ordinances relating to Technical Requirements for
Road Vehicles, Articles 213 to 218.
If you wish to ride in road trac in Austria, you must ob-
serve Ordinance 146 / Bicycle Ordinance.
Make sure each time you use your bike that it actually is
in the prescribed roadworthy condition, that the brakes
are properly adjusted and that the bell and lighting set
comply with the relevant regulations in your country, in
Germany these are the Road Trac Licensing Regulations
(StVZO).
In some EU countries, battery-operated ont lights and
rear lights may only be used by road bikes weighing less
than 11 kg. They must always be carried and have an o-
cial approval (sinuous line and K number). All other bikes
must use dynamo lighting sets. Every component of the
system must carry the ocial test mark which identies it
as "approved". The applicable regulations in your country
apply in this regard, e.g. the Road Trac Licensing Regu-

I General User Manual 9
lations (StVZO) in Germany. When performing technical
modications, bear in mind that electrical components
must only be replaced by type-tested components.
6 Intended use
6.1 General information
Bikes are a means of transportation for one person. In
some countries, regulations exist governing the carrying
of passengers, such as the Road Trac Ordinance (StVO)
in Germany (tandem or bike child seat).
If you wish to carry luggage, you will require a suitable
xture on your bike. Bear in mind the maximum load-
bearing capacity of the carrier (see ¯Chapter 30 "Techni-
cal data").
Not every bike type is suitable for every surface. Bikes are
not designed to cope with extreme stresses such as jump-
ing or riding over steps.
You must not take part in competitions with your bike. The
only exceptions to this are bikes that are oered explicitly
for use in competitions.
The information in this User Manual applies for all bike
types.
Any deviations for individual bike types are identied
accordingly.
Observe the relevant user manual om the individual
component manufacturers which can be found on the CD
or in the Internet. If you have any questions once you
have read the documentation, your specialist cycle shop
will be pleased to provide assistance.

ticularly applies for non-observance of the safety informa-
tion and damage resulting (for example) om:
•ooad use,
•overloading or
•incorrect repairs.

10 I General User Manual
6.4 Mountain bike (MTB)/ cross bike
You can use these bikes ooad. You must not use these
bikes in road trac or competitions. If you wish to use
your bike on public roads, it must have the requisite
equipment features (see ¯Chapter 5 "Legal provisions").
The manufacturer and cycle shop will not accept liability
claims should the bike not be used as intended
.
This particularly applies for non-observance of the safety
information and damage resulting for example om:
•use in competitions,
•overloading,
•incorrect repairs.
•riding over steps,
•jumping,
•riding through deep water
•extreme stresses on non-designated MTB routes or
MTB courses.
6.5 Road bike / tness bike
You may use these bikes on public roads for training pur-
poses. You may use road bikes weighing up to 11 kg with-
out permanently tted dynamo lighting. If you choose to
do so, you must carry a battery-operated ont light and a
rear light. If the light has the required approval, there will
be an embossed sinuous line and K-number on it.
When using road bikes that weigh more than 11 kg in road
trac, the required equipment features must be installed.
Please familiarise yourself with the applicable regula-
tions.
The bike is exempt om these requirements for the dura-
tion of ocially approved cycling events.
The manufacturer and cycle shop will not accept liability
claims should the bike not be used as intended. This par-
ticularly applies for non-observance of the safety informa-
tion and damage resulting for example om:
•ooad use,
•overloading,
•incorrect repairs or
•use in competitions,
6.6 BMX
These bikes are designed for BMX routes and/or BMX prac-
tice facilities.
In some EU countries, they are not approved for use in
road trac, e.g. by the Road Trac Licensing Regulations
(StVZO) in Germany, and in this case must not be used for
this purpose (see ¯Chapter 5 "Legal provisions").Always
wear a helmet and protective clothing, such as elbow and
knee pads.
The brakes normally installed on BMX bikes produce a
less eective braking action. You should therefore bear in
mind that this increases the braking distance, especially
in wet conditions. Please test this thoroughly in a safe
location and always adjust your handling accordingly.
The manufacturer and cycle shop will not accept liability
claims should the bike not be used as intended
.
This particularly applies for non-observance of the safety
information and damage resulting for example om
•use in competitions,
•overloading,
•incorrect repairs.
•riding over steps or
•jumping.

I General User Manual 11
7 Before the rst ride
Make sure that your bike is ready for use and is set up
for your body size.
Check the following:
•Positioning and secure fastening of saddle and
handlebar
•Installation and correct adjustment of the brakes
•Secure fastening of wheels in ame and fork
Adjust the handlebar and stem until you nd a safe
and comfortable riding position. Instructions on how
to adjust the handlebar are provided in ¯Chapter 9.3
"Adjusting the handlebar position".
Adjust the saddle until you nd a safe and comfort-
able riding position. Instructions on how to adjust the
saddle are provided in ¯Chapter 9.2 "Adjusting the
seat position".
Make sure the brake levers are always within easy
reach and that you know how to operate the right/
lebrake levers and where to nd them. Make a note
of which brake lever operates the ont and which the
rear wheel brake.
Modern brake systems can have a far more powerl
and dierent braking eect than those you are already
familiar with. Before setting o, familiarise yourself
with the eects of the brakes on a safe trac-ee
area.
If you are using a bike with carbon-bre rims, bear
in mind that the braking behaviour of this material is
much poorer than aluminium rims.
Make sure that the wheels are securely fastened in the
ame and forks. Check that the quick-release device
and all important fastening screws and nuts are se-
curely fastened.
¯Chapter 9.2.2 "Operating the quick-release device"
contains instructions on how to operate quick-release
devices safely and ¯Chapter 30 "Technical data" con-
tains a table of the tightening torques for important
screws and nuts.
Check the tyre pressure. Information on the pre-
scribed tyre pressure appears on the tyre sidewall.
Never inate the tyres to less than the minimum or
more than the maximum specied tyre pressure. As a
rule of thumb, e.g. when on the road, you can check
the tyre pressure as follows: If you press your thumbs
into the inated tyre, there should not be much give
in the tyre even if you press hard.
Check the tyres and rims for damage, foreign bodies,
e. g. glass agments or sharp stones and deformation.
If cuts, cracks or holes are visible, do not ride o. In-
stead, take your bike to a professional bike workshop
and have it checked.

12 I General User Manual
8 Before every ride
Although a great deal of care has been taken during
production and assembly, parts may still come loose
or change nction during transportation for example.
You should therefore always check the following be-
fore every ride:
•Bell and lighting are working properly and se-
curely fastened
•Brake system is working properly and securely
fastened
•If a hydraulic brake is tted to your bike, make
sure the lines and connections are tight
•Check the tyres and rims for damage and foreign
bodies and check the wheel runs true, especially
aer riding ooad
•Sucient tread depth on the tyres
•The suspension elements are in working order
and are securely fastened
•Screws, nuts and quick-release devices are se-
cure
•Frame and fork for deformation and damage
•Handlebar, handlebar stem, seatpost and saddle
in the correct position and safely and properly
secured
If you are not sure whether your bike is in a technical-
ly sound condition, do not ride it and have it checked
by a professional bike workshop instead.
9 Setting up the bike for the rider
Road bikes or mountain bikes can also be supplied with-
out pedals.
Proceed as follows if you wish to t pedals to your bike
yourself:
9.1 Fitting the pedals
iCoat both pedal threads with lubricant (grease).
The lepedal has a le-handed thread which is nor-
mally indicated by an "L" embossed on the axle. The
right pedal has a right-handed thread which is nor-
mally indicated by an embossed "R".
Axle with right pedal thread Axle with lepedal thread
iScrew the lepedal anticlockwise into the le
crank.
iScrew the right pedal clockwise into the right crank
(on the side of the bike chain).
iTighten both pedals using a suitable size15
open-ended spanner or Allen key. Tighten all
screws to the prescribed torque (¯Chapter 30
"Technical data"). If you do not do this, the ped-
als may come loose.

I General User Manual 13
Make sure you t or screw in the pedals straight, as
otherwise you could damage the thread in the crank
arm beyond repair.
1 MTB system pedals
2 Touring or sports pedals
3 Road bike system pedals
123
Only use the designated cleats and shoes for MTB,
racing and system pedals. If you use other cleats/
shoes you may slip out of the pedals.
Riders who are inexperienced in the use of MTB system
pedals or road system pedals, also referred to as click
pedals, are vulnerable to falls with potentially serious
consequences. If you use system pedals, practise clicking
into the pedal and releasing the shoe om the pedal when
the bike is stationary. Never practise this in road trac.
Read the user manual of the pedal and shoe manufacturer.
You can also nd more information on this subject in
the Internet. A list of links is provided in ¯Chapter 29
"Link list".
9.2 Adjusting the seat position
9.2.1 Adjusting the bike saddle
The seat position is decisive for your well-being and cy-
cling performance.
iDo not remove or change the seatpost or saddle
clamp. If you change or modicomponents, this
renders the warranty invalid.
iTighten all screws to the prescribed torque as
otherwise screws could shear oand compo-
nents could come loose or detach altogether (see
¯Chapter 30 "Technical data").
Only work on the bike if you have the correct tools
and requisite knowledge. Always have complex or
safety-relevant work carried out by a specialist cycle
shop.
9.2.2 Operating the quick-release device
iAll quick-release devices must be tightened se-
curely before you set o. Check this before every
journey.
iIf you leave your bike unattended, check that all
quick-release devices are correctly secured be-
fore setting oagain.
iWhen closing the quick-release lever to lock it,
it must be necessary to apply a force that causes
you to make a st with your hand as otherwise
the quick-release device could come loose.

To open the quick-release device, proceed as follows:
iThrow back the quick-release lever so that its inner
face or the lettering OPEN is visible.
iOpen the quick-release device as far as possible.
iTurn the adjusting nut anticlockwise to rther
slacken the quick-release device.
To close the quick-release device, proceed as follows:
iAdjust the clamping strength by turning the adjust-
ing nut.
iIf the quick-release device closes too easily, open
it again and turn the adjusting nut clockwise.
iIf the quick-release device still closes too easily,
repeat the previous step.
iIf the quick-release device is too dicult to close,
turn the adjusting nut anticlockwise.
iTurn back the quick-release lever om the OPEN
position so you can see the outer side of the lever
or the lettering CLOSE.
iWhen closed, quick-release levers must lie at
against the ame, fork and saddle clamp. Make
sure that quick-release devices for the hubs point
backwards when closed as otherwise they could
snag on obstructions when the bike is moving
and open. This could lead to serious accidents.
9.2.3 Determining the correct saddle height
iSit on the bike saddle.
iTry to reach the pedal with your heel when it is in
the bottom position. Your knee should be more or
less lly straightened out.
iPlace the balls of your feet on the centre of the
pedal. If your knee is now slightly bent, the saddle
height is correct.
Never tighten the seatpost if the maximum mark or
stop mark is above the top of the seat tube as other-
wise you could injure yourself or damage the seat-
post. Always observe the specied tightening torques.
In ll-suspension mountain bikes the seat tube is also
open at the bottom, so the seatpost should only be insert-
ed a certain distance downwards to ensure the rear swing
arm and suspension element never come into contact
when the bike is in use.

I General User Manual 15
The minimum insertion depth is marked on the seat-
post. If this is not the case, the minimum insertion
depth must be 7.5 cm. In ames with long seat tubes
that project beyond the top tube, the minimum inser-
tion depth is 10 cm.
Observe stop
mark.
9.2.4 Adjusting the saddle angle
iYour bike saddle should be as close as possible to
horizontal.
iYou can make use of longer bike rides to nd out
what your most comfortable seat position is. If you
want to tilt the saddle, try tilting it very slightly
forwards. If you tilt the saddle back, this can quick-
ly lead to pain or physical injury.
Adjust the saddle angle as follows:
iTurn the clamping screw anticlockwise to loosen it.
iTilt the bike saddle to the required angle.
iTurn the clamping screw clockwise to tighten it.
(For tightening torques see ¯Chapter 30 "Technical
data").
Adjusting the saddle angle
9.2.4.1 With a two-bolt seatpost
Some seatposts have two screws for adjusting the sad-
dle angle, one in ont of and one behind the seat tube.
If you want to tilt the saddle forwards, loosen the rear
screw with an Allen key and tighten the ont screw by the
same number of revolutions. To tilt the saddle backwards,
loosen the ont screw and tighten the other to the same
degree. Then retighten both screws observing the correct
tightening torque (see ¯Chapter 30 "Technical data").

9.2.4.2 With a seatpost saddle clamp
If the saddle is attached to the seatpost by a clamp, the
clamping nut will be at the side. Adjust the saddle angle
as follows:
iTurn the clamping nut anticlockwise to loosen it.
You may need to counter the nut on the other side
using another wrench.
iTilt the bike saddle to the required angle.
iTurn the clamping nut clockwise to tighten it. You
may need to counter the nut on the other side us-
ing another wrench. Use the correct tightening
torque (see ¯Chapter 30 "Technical data").

9.2.4.3 With a suspension seatpost
Suspension seatposts reduce vibrations caused by uneven
roads thereby reducing stress on the spinal column.
If you need to adjust the suspension elements in the seat-
post, consult your specialist cycle shop.
Suspension seatpost
9.3 Adjusting the handlebar position
Tighten all screws to the prescribed torque as other-
wise screws could shear oand components could
come loose or detach altogether (see ¯Chapter 30
"Technical data").
You can also inuence your riding position by changing
the handlebar height.
The lower you set the handlebar, the rther you will have
to lean forwards. This increases the strain on your wrists,
arms and upper body and you will need to bend your back
rther.
The higher the handlebar is, the more upright your riding
position will be. This increases the stress on your spinal
column due to jolting.
You can determine a handlebar height that best suits your
body size as follows:
iSit on the bike saddle.
iAsk another person to hold the bike steady if
required.
iBend your upper body towards the handlebar until
you have found a position that is comfortable for
your back.
iStretch out your arms towards the handlebar.
iNote the approximate position of your hands and
set the handlebar at this height.
9.3.1 Adjusting / aligning the handlebar
height with a conventional handlebar
stem
To release the stem shain the head tube, proceed as
follows:
iRelease the stem expander bolt to loosen the han-
dlebar stem. Turn it anticlockwise by two or three
revolutions using an Allen key.
iClamp the ont wheel between your legs to pre-
vent the bike fork om turning with the stem sha.
iHolding the handlebar by the handles, turn it om
right to leand vice-versa.
iIf it is not possible to do this, tap lightly on the
stem expander bolt with a plastic hammer to loos-
en the clamping xture inside the stem.
iSet the handlebar stem to the required height.
iAlign the handlebar so that it is exactly at right
angles to the ont wheel.
iTo secure the stem shaagain, turn the stem ex-
pander bolt clockwise using an Allen key until it is
tight (see ¯Chapter 30 "Technical data").

I General User Manual 17
Never tighten the handlebar stem if the maximum
mark or stop mark is above the top of the sha. If you
cannot nd a mark, insert the handlebar stem into
the head tube to a depth of at least 6.5 cm. If you do
not do this, the handlebar stem could come loose or
break.
9.3.2 Adjusting the handlebar height with
A-head systems
With the A-head stems shown here, the handlebar height
must be adjusted by a professional bike workshop.
9.3.3 Aligning handlebars with A-head
systems in relation to the ont wheel
To align the handlebar with the ont wheel, proceed as
follows:
iLoosen the hexagon socket screws on the rear of
the handlebar stem by turning them anticlockwise
with an Allen key.
iTurn the handlebar so that it is exactly at right
angles to the ont wheel.
iTighten the hexagon socket screw by turning it
clockwise with an Allen key (see ¯Chapter 30
"Technical data").
9.3.4 Adjusting the handlebar position by
turning the handlebar
Loosen the hexagon socket screws on the ont of the
stem. Turn the handlebar until you nd the position that
is comfortable for you. Make sure that the handlebar is
always exactly in the centre of the stem. Now retighten the
hexagon socket screws by turning them clockwise. If the
tightening torque is stamped on the stem, use this value,
and if not, use the tightening torques in ¯Chapter 30
"Technical data".
Once you have adjusted the handlebar, you will also need
to adjust the brake levers and gear-shihandles. Loosen
the hexagon socket screws on the handle grips. Sit on
the saddle and put your nger on the lever. Turn the le-
ver until your hand and lower arm are in a straight line.
Retighten the screws in the handle grips by turning them
clockwise. (For tightening torques see ¯Chapter 30 "Tech-
nical data").

9.3.5 Adjusting the handlebar height with an
adjustable handlebar stem
With some types of handlebar stems, you can vary the
handlebar tilt. The stem angle can be adjusted via the
clamping screws which are on the side of the articulation
or the top/bottom of the stem. Models equipped with ad-
ditional stop notches or adjusting screws are available.
Hexagon socket screw
(integrated stop notch)
Adjusting screw
Adjust the handlebar tilt as follows:
iUndo the clamping screw by turning it anticlock-
wise through two or three revolutions using an
Allen key.
iIf you own a model that is also equipped with
detents, continue turning the clamping screw anti-
clockwise to disengage the detents.
iIf you own a model with integrated stop notch,
loosen the screw of the stop notch. In many stem
types this is located on the underside of the stem.
iTilt the handlebar stem to the required angle.
iTo fasten the handlebar stem, tighten the clamping
screw clockwise using an Allen key . If tightening
torques are specied on the stem, use exactly these
torques, and if not, refer to the table of tightening
torques in ¯Chapter 30 "Technical data".
iIn models with an integrated stop notch, tighten
the screw of the stop notch carelly clockwise.
In doing so, the stop notch must engage with the
teeth.
10 Frame
The form of the ame depends on the bike type and nc-
tion. Frames are manufactured om dierent materials
– steel or aluminium alloys or carbon (carbon bre), for
example.
The ame number of the bike is stamped on the seat
tube, the dropout or the bottom bracket housing.
It may also be found on the motor suspension in Pe-
delecs. The bike can be identied by the ame num-
ber if it is stolen. To identithe bike properly, it is
important to note down the whole number in the right
order.
Never ride your bike if the ame is warped or
cracked. On no account should you attempt to repair
damaged parts. This can lead to accidents. Replace
defective parts before you ride the bike again.
Aer an accident or crash, have your bike checked by
a professional bike workshop before riding it again. If
defects on the ame or components go unnoticed this
can lead to accidents.
If your bike does not roll forwards easily in a straight
line, this could mean that the ame is warped. In this
case, have the steering stability checked by a profes-
sional bike workshop.
