SOME NOTES ON THESE ORIGINAL
OPERATING INSTRUCTIONS
The illustration shows a typical city/trekking bike and an E-bike/pedelec
– this type corresponds to the WHEELER bicycle or WHEELER pedelec
that you have just purchased. Today’s bicycles and e-bikes/pedelecs
come in a great many types that are designed for specific uses and are
equipped accordingly.
In the present operating instructions bicycles with drive support and
described as EPACs in the European standard EN 15194 are referred to
as pedelecs. For a precise description of the different EPAC types see
the chapter “Intended Use”.
In these operating instructions the term “bicycle” will always be used
in general descriptions if this refers to city/trekking/children’s bicycles
and pedelecs. If the warnings or information relate only to pedelecs
then these will be marked with a special symbol.
Pay particular attention to the following symbols:
gThis symbol indicates an imminent risk to your life or health
unless you comply with the corresponding handling in-
structions given or take preventive measures.
a This symbol warns you of incorrect actions that could result
in damage to property and the environment.
I This symbol provides you with information about how to
handle the product or refers to a passage in the operating
instructions that deserves your special attention.
The following symbols always appear if it is necessary to bring your
attention to special points concerning pedelecs. If you have purchased
a WHEELER pedelec then you should pay special attention to this infor-
mation and these warnings. Please note as well in all cases the general
warning information given in these operating instructions.

GENERAL SAFETY NOTES
Dear Customer,
In purchasing this WHEELER bicycle
(a-e) you have chosen a product
of high quality and technology. Each component of your new WHEELER
bicycle has been designed, manufactured and assembled with great
care and expertise. Your WHEELER bicycle dealer gave the bicycle its
final assembly and adjustment to guarantee proper operation and many
enjoyable riding experiences with complete peace of mind from the very
first metres.
These operating instructions contain a wealth of information on the
proper use of your WHEELER bicycle, its maintenance and operation
as well as interesting information on bicycle design and engineering.
Please read these instructions thoroughly. We are sure that even if you
have been cycling all your life you will find useful and detailed infor-
mation. Bicycle and pedelec technology has developed at a very rapid
pace during recent years. Therefore, before setting off on your new
WHEELER bicycle, be sure to read at least the chapter “Before Your
FIRST Ride” first.
To have as much fun as possible during cycling, be sure to carry out the
functional check described in chapter “Before EVERY Ride” before
setting off.
Even a manual as big as an encyclopaedia could not describe every
possible combination of bicycle models and components or parts on
the market. These operating instructions therefore focus on your newly
purchased WHEELER bicycle and standard components and provide
useful information and warnings. In addition to this, your BionX system
operating instructions give important information and warnings on han-
dling your new WHEELER pedelec.
When doing any adjusting or servicing, be aware that the detailed in-
structions and information provided in these operating instructions only
refer to this WHEELER city/trekking bicycle or WHEELER pedelec.
The information included here is not applicable to any other bicycle
type. As bicycles and pedelecs come in a wide variety of designs with
frequent model changes, the routines described may require comple-
mentary information. Comply also with the instructions of the parts
manufacturers, which you can find on the enclosed CD.
Be aware that these instructions may require further explanation, de-
pending on the experience and/or skills of the person doing the work.
For some jobs you may require additional (special) tools or supplemen-
tary instructions. This manual cannot teach you the skills of a bicycle
mechanic.
Before you set off, let us point out a few things that are very important to
every cyclist: Never ride without a properly adjusted helmet and without
glasses
(f) and take care to always wear suitable, bright clothing. As a
minimum you should wear straight cut trousers
(g) and shoes (h) fitting
the pedal system. Always ride carefully on public roads and observe the
traffic rules so as not to endanger yourself or others.
This manual cannot teach you how to ride. Please be aware that cycling
is a hazardous activity that requires the rider to stay in control of his or
her WHEELER bicycle at all times.
Like any sport, cycling involves the risk of injury and damage. Keep
this in mind. When you decide to ride a bicycle or pedelec you need
to accept the risk inherent to cycling. Please note that on a bicycle you
have no protection technique around you (e.g. bodywork, ABS, airbag)
like you have in a car. Therefore, always ride carefully and do respect
the other road users. Never ride under the influence of drugs, medica-
tion, alcohol or when you are tired. Do not ride with a second person
on your WHEELER bicycle and never ride without having both hands on
the handlebars.

Observe the legal regulations concerning off-road cycling (a) (also for
pedelecs). These regulations may differ in each country. Please respect
nature when riding off-road. Only use your pedelec on signposted, well
maintained trails and hard-surface roads.
Always bear in mind that you travel rapidly and quietly when you are
riding a WHEELER pedelec. Do not startle pedestrians or other cyclists.
Always make others aware of your presence well ahead of time and by
ringing your bell or make use of the brakes so as to avoid accidents.
Familiarize yourself with your WHEELER pedelec. You can fi nd further
information in the chapters “Useful Tips for Riding a WHEELER
Pedelec“ and “Riding a WHEELER Speed Pedelec – Special Fea-
tures”.
If you bought a children’s bicycle
(b) , observe the chapter “Children’s
Bicycles” before your child sets off on it for the fi rst time. In some
countries there are specifi c regulations for children. Read the afore-
mentioned chapter before your child uses the bicycle for the fi rst time.
First of all, we would like to familiarize you with your WHEELER bicycle
or pedelec. Please unfold the cover of this manual. A WHEELER city/
trekking bike
(c) and a WHEELER pedelec (d) are shown as examples
in which all the necessary components are described. Leave the page
unfolded as you read so that you can easily locate the components as
they are referred to in the text.
gFor your own safety, never do work on your pedelec unless
you feel absolutely sure about it. If you are in doubt or if you
have any questions, please contact your WHEELER bicycle
dealer.
INTENDED USE
Keep in mind that every bicycle type is built for a specifi c intended use.
Be sure to use your WHEELER bicycle only according to its intended
use, as it may otherwise not withstand the stress and would fail and
cause an accident with unforeseeable consequences!
1. City/trekking bikes
(e) and children’s bicycles (f) are intended
for hard-surface roads, i.e. for tarred roads and bicycle lanes or
gravel fi eld tracks. Observe the traffi c rules when cycling on public
roads.
2. Pedelecs
(g+h) (Pedal Electric Cycles) or EPACs (Electrically
Power Assisted Cycles) are bicycles with an auxiliary motor that
only switches on when the pedals are moved by the rider. When
you stop pedalling, the motor switches off.
A driving licence is not required for riding a pedelec if the motor
assistance switches off automatically at a speed of 25 kmh/15
mph. You do not need an operating licence and need not insure the
pedelec either. Please do not confuse your pedelec with a speed
pedelec (S-Pedelec) (see item 4).
All regulations that apply to bicycles, also apply to pedelecs, i.e.
they are allowed to or must use cycle paths without any restric-
tions. Wearing a helmet is recommended, but not compulsory.
Most pedelecs are designed for cycling exclusively on lanes and
roads with a smooth surface. Only use trails that are allowed for
bicycles. In general, typical pedelecs are not suitable for off-road
use. Using pedelecs off-road can result in crashes with unforesee-
able consequences.
If your pedelec does not look like a typical city or trekking bike (see
the cover), then please read the chapter “Before Your First Ride”.
U Please note that there are different types of pedelecs and
e-bikes which are subject to different overall legal condi-
tions. Check the class of your WHEELER pedelec or e-bike
in the bicycle card. Keep the specifi c regulations for your
pedelec/e-bike class in mind when riding on public roads
and also through the countryside.

3. Pedelecs (a+b) (Pedal Electric Cycles) as well as EPACs (Elec-
trically Power Assisted Cycles) with starting or pushing aid are
considered as motor vehicles with special authorization. Neverthe-
less, you do not need an operating licence and need not insure the
pedelec either. Wearing a cycle helmet is not compulsory either,
but highly recommended.
The starting or pushing aid provides assistance during pushing or
when doing a hill start, even without pedalling, up to a speed of 6
kmh / 3.7 mph.
These WHEELER pedelecs are not required to be insured for riding
on public roads.
U If you were born after 1st April 1965 you will require a
moped driving licence (driving licence class M) or a driving
licence for motor vehicles according to the German Bicycle
Association (ZIV).
U The laws and regulations concerning pedelecs, speed
pedelecs and e-bikes are currently being revised. Read the
daily press to keep yourself informed about current legisla-
tive changes.
The other regulations do not differ from those relating to pedelecs
(see item 2.).
4. Speed pedelecs are bicycles with an auxiliary motor which pro-
vide assistance to the rider even beyond a speed of 25 kmh / 15
mph, as long as you continue pedalling. Without pedalling a speed
pedelec provides assistance to a maximum speed of 20 kmh/12
mph.
Speed pedelecs are regarded as motor vehicles, have an operat-
ing licence or EU type approval, and are therefore subject to strict
guidelines regarding the replacement of components or making
any conversions.
It is mandatory to wear a helmet
(c) in Germany and Switzerland.
If you are riding a speed pedelec you may not use cycle paths
within built-up areas in Germany. The only exception to this is in
cases where the cycle path or lane has been approved for use
by mopeds (this is marked by an additional sign). Outside built-up
areas it is permissible to ride a speed pedelec on cycle paths and
lanes
(d) .
These speed pedelecs are required to have an operating licence
and to be insured as motor vehicle when riding on public roads
(e+f) . If you were born after 1st April 1965 you will require a
moped license (driving license class M) or a driving license for mo-
tor vehicles. You can obtain a moped license if you are aged 15 or
over. Enquire at your driving license agency.
In Switzerland you may ride your speed pedelec on paths and
tracks where mopeds are not allowed if you ride without drive as-
sistance to maximum 20 km/h (12 mph), with drive assistance to
maximum 25 km/h (15 mph) or with the motor switched off com-
pletely.
Be sure to also read the chapter “Riding a WHEELER Speed
Pedelec – Special Features”.
Most of the speed pedelecs
(g+h) are designed for cycling exclu-
sively on lanes and roads with a smooth surface. Only use trails that
are allowed for speed pedelecs / e-bikes. Typical speed pedelecs
are generally not suitable for off-road use. Using speed pedelecs
off-road can result in crashes with unforeseeable consequences.
I Comply also with the instructions of the parts manufactur-
ers, which you can find on the enclosed CD.
U For more information about the intended use of your
WHEELER pedelec as well as the permitted overall weight
(rider, pedelec and baggage) see the BionX system operat-
ing instructions and the bicycle card and read the chapter
“Before Your First Ride”.
U For more information on approval for the use of trailers and
child-carrier seats on your WHEELER pedelec please refer
to the BionX system operating instructions and the bicycle
card.

2. If you want to use your pedelec on public roads, it has to comply
with the respective legal requirements. These requirements may
vary in each country. The fittings of your bicycle are, therefore,
not necessarily complete. Ask your WHEELER bicycle dealer con-
cerning the laws and regulations applicable in your country or in
the country you intend to use your WHEELER bicycle. Have your
WHEELER bicycle equipped accordingly before using it on public
roads.
iWe very strongly recommend you to take out private liability
insurance. Ensure that your insurance covers you for dam-
age caused while riding the bicycle or pedelec. Contact an
insurance company or broker.
3. Are you familiar with the brake system
(e) ? Have a look at the bi-
cycle card and check whether the brake lever
(f) of the front brake
is on the side you are used to (right or left). If it is not, ask your
WHEELER bicycle dealer to switch the brake levers before you set
off for the first time.
Your new pedelec is equipped with modern brakes which may be
far more powerful than those that you were used to before. Be sure
to first practise using the brakes on a level, non-slip surface off
public roads!
You can find further information in the chapter “Brake System”
and in the instructions from the parts manufacturers, which you
can find on the enclosed CD.
4. Are you familiar with the type and functioning of the gears
(g+h) ?
Ask your WHEELER bicycle dealer to explain you the gear system
and make yourself familiar with your new gears in an area free of
traffic, if necessary.
You can find further information in the chapter “Gears” and in the
instructions from the parts manufacturers, which you can find on
the enclosed CD.

5. Are both the saddle and handlebars properly adjusted? The sad-
dle should be set to a height from which you can just reach the
pedal in its lowest position with your heel
(a) . Check whether your
toes reach to the floor when you are sitting on the saddle. Your
WHEELER bicycle dealer will be pleased to help you if you are not
happy with your seating position.
For more information see the chapter “Adjusting the WHEELER
Bicycle to the Rider”.
6. If your WHEELER bicycle is equipped with clipless or step-in ped-
als
(b) : Have you ever tried the shoes they go with? Do not set off
until you have practised engaging and disengaging the shoes from
the pedals when stationary. Ask your WHEELER bicycle dealer to
explain the pedals to you.
You can find further information in the chapter “Pedals and
Shoes” and in the instructions from the parts manufacturers,
which you can find on the enclosed CD.
7. If you have bought a WHEELER bicycle with suspension
(c+d) ,
you should ask your WHEELER bicycle dealer to adjust the suspen-
sion mechanism to your needs before delivery. Improperly adjusted
suspension components are liable to malfunction or damage. In
any case they will impair the performance of your bicycle as well as
your safety and pleasure whilst cycling.
You can find further information in the chapters “Suspension
Forks” and “Suspension Seat Posts” and in the instructions
from the parts manufacturers, which you can find on the enclosed
CD.
G Be aware that the distance you need to stop your bicycle
increases if you are riding with your hands on the bar ends
or on multi position handlebars. The brake levers are not
always within easy reach.
gBe sure to use your WHEELER bicycle only for its intended
use, as it may otherwise not withstand the stress and fail!
Danger of an accident!
gMake particularly sure there is enough space between your
crotch
(e) and the top tube so that you do not hurt yourself,
if you have to get off your pedelec quickly.
G Please note that in wet conditions the brake performance is
less effective and the tyre grip is reduced. Keep this fact in
mind in particular when riding on a wet road and do not ride
as fast as you would in dry conditions.
a A lack of practice when using clipless pedals
(f) or too much
spring tension in the mechanism can lead to a very firm
connection, from which you cannot quickly step out! Dan-
ger of an accident!
a Before hitching a trailer
(g) to your bicycle or mounting a
child-carrier seat
(h) , have a look at the bicycle card and
contact your WHEELER bicycle dealer.

ADDITIONAL INFORMATION “BEFORE YOUR FIRST RIDE”
WITH YOUR WHEELER PEDELEC
1. Have you ridden a pedelec yet? Please note the particular riding
characteristics of this revolutionary hybrid drive concept. Set off
for your first ride by selecting the lowest level of drive assistance!
Slowly approach the potential of your WHEELER pedelec in an area
free of traffic.
You can find further information in the chapters “Useful Tips for
Riding a WHEELER Pedelec” and “Riding a WHEELER Speed
Pedelec – Special Features” and in your BionX system operating
instructions.
2. Your WHEELER bicycle is designed for a maximum overall weight,
including rider, baggage and pedelec. The maximum overall weight
is specified in your BionX system operating instructions; if it is not,
then contact your WHEELER bicycle dealer.
H The weight distribution on pedelecs differs markedly from
the weight distribution on bicycles without drive assistance.
A pedelec is markedly heavier than a bicycle without drive
assistance. For this reason parking, pushing, lifting and
carrying the WHEELER pedelec is more difficult. Bear this
in mind when loading your pedelec into a car and unloading
it or when mounting it on a bicycle carrier system.
3. The rechargeable battery of your WHEELER pedelec
(a-c) must be
charged before you set off for the first time. Are you familiar with
the handling and mounting of the rechargeable battery? Before
you set off for the first time, check whether the battery is properly
mounted, that it has engaged audibly and that it is locked.
You can find further information in the chapter “Inserting and Re-
moving the Battery” in your BionX system operating instructions.
U Please note that the system switches itself off automatically
after 10 minutes without any actuation. You can find out
how to switch the system on again in the chapter "Operat-
ing the BionX Propulsion System" in your BionX system
operating instructions.
H We recommend that you charge your battery only during
the day and only in dry rooms which have a smoke or a fire
detector; but not in your bedroom. Place the battery during
the charging process on a big, non-inflammable plate made
of ceramics or glass! Unplug the battery once it has been
charged up.
H Charge your battery only with the supplied charger
(d+e) .
Do not use the charger of any other manufacturer, not even
when the connector of the charger matches your recharge-
able battery. The rechargeable battery can heat up, catch
fire or even explode!
H Do not park your WHEELER pedelec in strong sunshine.
4. The functions of your pedelec are operated with the buttons of the
control element
(f) on the handlebars. Are you familiar with all the
functions and displays?
Check whether you know the functions of all the buttons (g) . You
can find further information in the chapter “Operating the BionX
Propulsion System” in your BionX system operating instructions.
H Be aware that the brakes of your WHEELER pedelec are al-
ways more effective than the drive. If you face any problems
with your drive (e.g. because it pushes you forward before a
turn), slow down your WHEELER pedelec carefully.
H Pulling the brake lever of the rear brake
(h) stops the motor.
Emergency stop! However, if you have a front-mounted mo-
tor you must operate the front brake very carefully.
H When mounting your WHEELER pedelec, make sure not to
step on the pedals until you sit in the saddle and grip the
handlebars tightly, and that one pedal is at the lowest posi-
tion when you get on. The motor assistance might switch on
suddenly unexpectedly and result in an uncontrolled start of
your WHEELER pedelec. Danger of an accident!
U Check with your insurers that the pedelec as well as the
storekeeping and the charging of lithium-ion batteries are
covered by your household and fire insurance. Read the
daily press to keep yourself informed about current legisla-
tive changes.

BEFORE EVERY RIDE
Your WHEELER bicycle has undergone numerous tests during produc-
tion and a final check has been carried out by your WHEELER bicycle
dealer. Nevertheless, be sure to check the following points before every
ride to exclude any malfunctioning that may be due to the transport of
your WHEELER bicycle or to the work a third person may have per-
formed on your WHEELER bicycle before delivery:
1. Are the quick-release levers
(a) of the front and rear wheel properly
closed and the bolts of the seat post and other components ac-
curately tightened?
You can find further information in the chapter “How to Use
Quick-Releases” and in the instructions from the parts manufac-
turers, which you can find on the enclosed CD.
2. Are the tyres in good condition and do they have sufficient pres-
sure? The minimum and maximum pressure (in bar or PSI) is indi-
cated on the side of the tyre
(b) .
Note that the tyres of a WHEELER pedelec typically require some-
what more pressure than you are generally used to with your city or
trekking bike.
You can find further information in the chapter “Wheels and Tyre
Equipment” and in the instructions from the parts manufacturers,
which you can find on the enclosed CD.
3. Spin the wheels to check for true running
(c). Watch the gap be-
tween rim and brake pad or, in the case of wheels with disc brakes
(d) , between frame and rim or tyre. Wheels which do not run true
can be an indication of tyres with ruptured sides or broken axles or
spokes.
You can find further information in the chapter “Wheels and Tyre
Equipment” and in the instructions from the parts manufacturers,
which you can find on the enclosed CD.
4. Test the brakes when stationary by firmly pulling the brake levers
towards the handlebars
(e) . The brake pads of rim brakes must
hit the rim evenly with their entire surface
(f) without touching the
tyre during braking or in the open state or in between. Make sure
you cannot pull the brake levers all the way to the handlebars and
check the cables for leaks in the case of hydraulic brakes.
Check the thickness of the brake pads, as well. With disc brakes
you should directly get a positive braking response. If you have to
actuate the brake lever more than once to get a positive braking
response, have your WHEELER bicycle checked by your WHEELER
bicycle dealer.
You can find further information in the chapter “Brake System”
and in the instructions from the parts manufacturers, which you
can find on the enclosed CD.
5. Let your WHEELER bicycle bounce on the ground from a small
height. If there is any rattling, see where it comes from. Check the
bearings and the bolts, if necessary.
6. If you want to ride on public roads, make sure your WHEELER
pedelec is equipped according to the applicable regulations of your
country
(g+h) .
Riding without lights and reflectors in dark or dim conditions is very
dangerous. A lighting set that corresponds to the regulations is a
must on public roads. Turn on the lights as soon as dusk sets in.
For more information see the chapter “Legal Requirements for
Riding on Public Roads“.

7. If you have a WHEELER bicycle with suspension (a) , press down on
your bicycle and see whether the suspension components retract
and extend as usual
(b) .
You can find further information in the chapters “Suspension
Forks” and “Suspension Seat Posts” and in the instructions
from the parts manufacturers, which you can find on the enclosed
CD.
8. If your bicycle has a kick-stand
(c) , make sure it is fully raised
before you set off. Danger of an accident!
9. Do not forget to take a high-quality D-lock (d) or chain lock with
you on your ride. The only way to effectively protect your WHEELER
bicycle against theft is to lock it to an immovable object.
10. Remove the cycle computer when you park your WHEELER bicycle
or pedelec.
G Improperly closed fastenings can cause parts of your
WHEELER pedelec to come loose and result in serious ac-
cidents!
G Do not use your WHEELER bicycle if it fails on any one of
these points! Riding a defective WHEELER bicycle can result
in serious accidents! If you are in doubt or if you have any
questions, please contact your WHEELER bicycle dealer.
G During use your WHEELER bicycle or pedelec is undergoing
stress resulting from the surface of the road and through
the rider’s actions. Due to these dynamic loads, the differ-
ent parts of your bicycle react with wear and fatigue. Please
check your WHEELER bicycle or pedelec regularly for wear
marks, scratches, deformations, colour changes and any
indication of cracking. Components which have reached the
end of their service life may break without previous warn-
ing. Let your WHEELER bicycle dealer maintain and service
your WHEELER bicycle regularly and in cases of doubt it is
always best to replace components.
G Be aware that the distance you need to stop your bicycle
increases if you are riding with your hands on the bar ends
or on multi position handlebars. The brake levers are not
always within easy reach.
ADDITIONAL INFORMATION “BEFORE EVERY RIDE” WITH
YOUR WHEELER PEDELEC
1. Are the connections of the rechargeable battery, the control ele-
ment on the handlebars and the drive system
(e) properly plugged
in?
You can find further information in the chapters “Inserting and
Removing the Battery” and “Operating the BionX Propulsion
System” in your BionX system operating instructions.
2. Is your battery fully charged
(f) ?
Remember to fully recharge the battery after each longer ride
(e.g. less than 50% charged). Modern lithium-ion batteries have
no memory effect. However, it does not matter if your WHEELER
pedelec is left as it is for a short time (e.g. overnight) when less
than 50% charged. However, you should not wait until the battery
is fully discharged!
For more information see the chapter “Useful Information for
Proper Handling of the Battery” and the chapter “Handling and
Charging the battery” in your BionX system operating instruc-
tions.
3. Does the display on the control element and the cycle computer on
the handlebars show all the values
(g) ?
Are there any error messages or warnings on the display? Check
the values are correct before every ride. Do not set off on your
WHEELER pedelec under any circumstances if the control element
shows a warning.
You can find further information in the chapter “Operating the
BionX Propulsion System” in your BionX system operating in-
structions.
4. Is the battery tight in its holder and properly locked up
(h) ? Never
set off with a loose and unlocked battery.
You can find further information in the chapter “Inserting and Re-
moving the Battery” in your BionX system operating instructions.

AFTER AN ACCIDENT
1. Check whether the wheels are still firmly fixed in the drop-outs and
whether the rims are still centred with respect to the frame or fork
(a) . Spin the wheels and observe the gap either between brake
pads and rim sides or between frame and tyre. If the width of the
gap changes markedly and you have no way to true the rim where
you are, you will need to open the rim brake a little so that the rim
can run between the brake pads without touching them. Please
note that in this case the brakes may not act as powerfully as you
are used to.
You can find further information in the chapters “Brake System”,
“How to Use Quick-Releases” and “Wheels and Tyre Equip-
ment” and in the instructions from the parts manufacturers, which
you can find on the enclosed CD.
2. Check that handlebars and stem are neither bent nor broken and
that they are level and upright
(b) . Make sure the stem is firmly
fixed on the fork by trying to turn the handlebars relative to the front
wheel. Briefly lean on the brake levers to make sure the handlebars
are firmly fixed in the stem
(c) . Realign the components, if neces-
sary, and carefully tighten the bolts to ensure reliable clamping of
the components. The maximum torque values are printed directly
on the components or specified in the enclosed operating instruc-
tions.
You can find further information in the chapters “Adjusting the
WHEELER Bicycle to the Rider” and “Headset” and in the in-
structions from the parts manufacturers, which you can find on the
enclosed CD.
3. Check whether the chain still runs on the chainrings and the
sprockets. If your WHEELER bicycle fell over to the chain side,
verify the proper functioning of the gears. Ask somebody to lift the
WHEELER bicycle by the saddle and carefully shift through all the
gears. Pay particular attention when shifting to the small gears and
make sure the rear derailleur does not get too close to the spokes
as the chain climbs onto the larger sprockets
(d) .
If the rear derailleur or the drop-outs/derailleur hanger are bent,
the rear derailleur may collide with the spokes. This can result in
damage to the rear derailleur, the rear wheel and the frame. Check
the function of the front derailleur, as a displaced front derailleur
can throw off the chain, thus interrupting the drive train of your
WHEELER bicycle.
You can find further information in the chapter “Gears” and in the
instructions from the parts manufacturers, which you can find on
the enclosed CD.
4. Make sure the saddle is not out of alignment, using the top tube
(e)
or the bottom bracket shell as a reference. If necessary, open the
clamp, realign the saddle and retighten the clamp
(f) .
You can find further information in the chapters “Adjusting the
WHEELER Bicycle to the Rider” and “Headset” and in the in-
structions from the parts manufacturers, which you can find on the
enclosed CD.
5. Lift your WHEELER bicycle up a few centimetres and let it bounce
onto the ground
(g) . If this causes any sort of noise, search for
loosened bolts or components. Retighten them, if necessary.
6. Finally, take a good look at the whole WHEELER bicycle to detect
any deformations, colour changes or cracks
(h) .

f
Ride back very carefully by taking the shortest route possible, only if
your WHEELER bicycle
(a) or WHEELER pedelec (b) went through this
check without any problems. Do not accelerate or brake hard and do
not ride your bicycle out of the saddle. If you are in doubt about the
performance of your WHEELER bicycle, have yourself picked up by car,
instead of taking any risks.
Back home you need to check your WHEELER bicycle thoroughly once
again. The damaged parts must be repaired or replaced. Ask your
WHEELER bicycle dealer for help.
G Deformed components, especially those made of alumini-
um, can break without previous warning. They may not be
repaired, i.e. straightened, as the imminent risk of breakage
will remain. This applies in particular to the fork, the han-
dlebars, the stem, the cranks, the seat post and the pedals.
When in doubt, it is always recommended that you have
these components replaced, as your safety comes first. Ask
your WHEELER bicycle dealer for help.
G If your WHEELER bicycle is assembled with carbon com-
ponents, it is imperative that you have it checked by your
WHEELER bicycle dealer after an accident or similar inci-
dent. Carbon is an extremely strong material which com-
bines high resistance with low weight. However, one of the
inherent properties of carbon is that possible overstress
may compromise the inner carbon-fibre structure without
showing any visible deformation, as is the case with steel or
aluminium. A damaged component can fail without previous
warning. Danger of an accident!
ADDITIONAL INFORMATION “AFTER AN ACCIDENT” WITH
YOUR WHEELER PEDELEC
1. Check the rechargeable battery (c+d) . If the rechargeable battery
is no longer properly in its holder or shows any damage, do not use
your WHEELER pedelec any longer, or at least, not in assistance
mode. Switch off the motor and the battery separately, if neces-
sary. A damaged battery can lead to a short-circuit or a sudden
failure of your WHEELER pedelec assistance right at the moment
when you need it.
Damage to the outer housing of the rechargeable battery can result
in the entry of water or moisture and that can lead to short circuits
or electric shocks. The rechargeable battery could catch fire or
even explode! In such a case contact your WHEELER bicycle dealer
immediately.
2. Check the display
(e) . Are all the values displayed as usual?
Do not use your WHEELER pedelec if the display shows an error
message or a warning. If necessary, switch off the system com-
pletely and wait at least 10 seconds before checking it again.
Do not set off on your WHEELER pedelec with drive assistance if
the control element shows a warning. In such a case contact your
WHEELER bicycle dealer immediately.
You can find further information in the chapter “Operating the
Propulsion System” in your BionX system operating instructions.
3. Let your WHEELER pedelec bounce on the ground from a low
height. If there is any rattling, see where it comes from
(f) . Check
the bearings, the bolts and the proper seating of the battery and
the connectors, as necessary.
You can find further information in the chapter “Inserting and Re-
moving the Battery” in your BionX system operating instructions.

HOW TO USE QUICK-RELEASES
Most city/trekking bikes are fitted with quick-releases to ensure fast
adjustments, assembly and disassembly. Be sure to check that all the
quick-releases are tight before you set off on your WHEELER bicycle.
Quick-releases should be handled with the greatest care, as they di-
rectly affect your safety.
Practise the proper use of quick-releases to avoid any accidents.
Quick-release mechanisms essentially consist of two operative ele-
ments:
1. The hand lever on one side of the hub which creates a clamping
force via a cam when you close it
(a) .
2. The tightening nut on the other side of the hub with which the initial
tension on the threaded rod (quick-release axle) is set
(b) .
G Make sure that the levers of both wheel quick-releases are
always on the side opposite the chain drive
(c) . This will
help you to avoid accidentally mounting the front wheel the
wrong way round. In the case of bicycles with disc brakes
and quick-releases having a 5-mm-axle, it may be reason-
able to mount both quick-releases with the lever on the side
of the chain drive. This would help you not to come into con-
tact with the rotor and prevent you from having your fingers
burnt. If you are in doubt or if you have any questions, then
contact your WHEELER bicycle dealer.
G Never ride your WHEELER bicycle without having checked
first whether the wheels are securely fastened
(d) . Danger
of an accident!
G Do not touch the rotor directly after having stopped – you
may burn your fingers! Always let the rotor cool down be-
fore opening the quick-release!
A If your WHEELER bicycle is equipped with quick-releases,
be sure to lock the wheels together with the frame to an
immovable object when you leave the bicycle outside.
How to Fasten Components Securely with a Quick-Release
Open the quick-release. The marking “Open“ on the lever should be-
come visible now
(e) .
Make sure the component to be fastened is in the correct position.
You can find further information in the chapters “Wheels and Tyre
Equipment” and “Adjusting the WHEELER Bicycle to the Rider”
and in the instructions from the parts manufacturers, which you can
find on the enclosed CD.
Move the lever back, as if to close it. Now you should be able to read
”Close“ on the outside of the lever
(f) . When you start closing the lever
you should feel virtually no resistance with your hand until half way
(g) .
Over the second half of its travel the resistance you feel should increase
significantly. Towards the end of its travel you should need very much
strength to close the lever. Use the ball of your thumb to push it in all
the way while your fingers pull on an immovable part, such as the fork
(h) or the rear stay, but not on a brake rotor or spoke.
In its end position, the lever should be at right angles to the quick-
release axle, i.e. it should not stick out to the side. The lever should lie
close to the frame or the fork so that it cannot be opened accidentally.
Make sure, however, that the lever is easy to handle for actual quick
use.
To check whether the lever is securely locked, apply pressure to the end
of the lever and try to turn it while it is closed. If you can turn the lever
around, open it and increase the preload. Screw the tightening nut on
the opposite side clockwise by half a turn. Close the quick-release lever
and check it again for tightness.

f
Finally lift the bicycle a few centimetres so that the wheel no longer
touches the ground and hit the tyre from above
(a) . If it is properly
fastened, the wheel will remain firmly fixed in the drop-outs of the frame
or fork without producing any rattling.
If your seat post is equipped with a quick-release mechanism
(b+c) ,
check whether the saddle is firmly fixed by trying to twist it relative to
the frame
(d) .
G With an insufficiently closed quick-release the wheel can
come loose, thus creating a serious risk of accident!
I You can replace the quick-release levers by an anti-theft
lock. For these you require either a specially coded key or
an Allen key. If you are in doubt or if you have any questions,
then contact your WHEELER bicycle dealer.
ADJUSTING THE WHEELER BICYCLE TO THE
RIDER
Your body height and proportions are decisive for the choice of the
frame size of your WHEELER bicycle. Make particularly sure there is
enough space between your crotch and the top tube so that you do not
hurt yourself, if you have to get off your pedelec quickly
(e) .
By choosing a specific type of bicycle you roughly determine the posture
you will be riding in (f) . However, some components of your WHEELER
bicycle are especially designed so that you can adjust them to your body
proportions up to a certain degree
(g) . These include the seat post, the
stem and the brake levers.
As these adjustments require know-how, experience, the appropriate
tools and a certain amount of skill, you should restrict yourself to a posi-
tion control. Ask your WHEELER bicycle dealer for the correct seating
position or if you want something changed. They will see to your wishes
the next time you leave your WHEELER bicycle at the workshop, e.g. for
the first inspection.
After any adjustment/assembly work, be sure to make a short func-
tional check as described in the chapter “Before Every Ride” and do
a test ride in an area free of traffic.
G If you have a very small frame, there may be the danger of
your foot colliding with the front wheel. Therefore, make
sure your cleats are properly adjusted.
G All tasks described in the following require the know-how of
a mechanic and appropriate tools. Make it a rule to tighten
the bolted connections always with greatest attention. In-
crease the torque values bit by bit, checking the fit of the
component in between. Use a torque wrench and never
exceed the maximum torque values! You can find these in
the chapter “Recommended Torque Settings for Compo-
nents”, on the components themselves and/or in the in-
structions from the parts manufacturers, which you can
find on the enclosed CD.
I If sitting on the saddle causes you trouble, e.g. because
it numbs your crotch, this may be due to the saddle. Your
WHEELER bicycle dealer has a very wide range of saddles
available and would be glad to offer advice
(h) .

SETTING THE SADDLE HEIGHT
The correct saddle height for almost all bicycle types is the height which
gives maximum pedalling comfort and efficiency. When pedalling, the
ball of your foot should be positioned above the centre of the pedal axle.
With your feet in this position you should not be able to stretch your
legs completely straight at the lowest point, otherwise your pedalling
will become awkward.
Check the height of your saddle with flat-soled shoes. This is best done
with suitable cycling shoes.
Sit on the saddle and put your heel on the pedal at its lowest point
(a) . Your leg should be fully stretched and your hips should remain
horizontal.
To adjust the saddle height loosen the quick-release lever (b) (see the
chapter “How to Use Quick-Releases”) or the binder bolt of the seat
post clamp
(c) at the top of the seat tube.
The latter requires suitable tools, such as an Allen key, with which you
turn the bolt two to three turns anticlockwise. Now you can perform the
vertical adjustment of the seat post.
Be sure not to pull out the seat post too far – the mark on the seat post
(end, max., min., stop or the like) should always remain within the seat
tube
(d) – and always grease the part of an aluminium or titanium seat
post that is inserted into a seat tube made of aluminium, titanium or
steel. Do not grease carbon seat posts and/or carbon seat tubes in the
clamping area! Use special carbon assembly paste instead.
Align the saddle with the frame by using the saddle nose and the bot-
tom bracket shell or top tube as a reference point
(e) .
Clamp the seat post tight again, by closing the quick-release, as de-
scribed in chapter “How to Use Quick-Releases” or by turning the
seat post binder bolt clockwise in half turns. You should not need much
strength in your hands to clamp the seat post sufficiently tight. Other-
wise the seat post does not match the frame.
Verify in between that the seat post is sufficiently tight by taking hold
of the saddle at both ends and then trying to rotate the seat post inside
the seat tube. If it does rotate, gently retighten the clamping bolt by half
a turn and do the check again.
Does the leg stretch test now produce the right result
(f) ? Check by
moving your foot and pedal to the lowest point. When the ball of your
foot is exactly above the pedal centre in the ideal pedalling position,
your knee should be slightly bent. If it is, you have adjusted the saddle
height correctly.
Check whether you can touch the ground safely while sitting on the
saddle by stretching your feet to the ground. If you cannot, you should
lower the saddle a little, at least to begin with.
A Tighten carefully by approaching the prescribed maximum
torque in small steps (0.5 Nm increments) and check in be-
tween the proper fit of the component. Never exceed the
maximum torque value specified by the manufacturer
(g) !
G Never ride your bike with the seat post drawn out beyond
the end, limit, maximum, or stop mark! The seat post might
break or cause severe damage to the frame. In the case
of frames with seat tubes that extend beyond the top of
the frame’s top tube, the seat post should be inserted into
the seat tube at least below the bottom of the top tube and
below the top of the seat stays! If the seat post and frame
require different minimum insertion depths, you should opt
for the deeper insertion depth.
G Never apply grease or oil into a seat tube of a frame made
of carbon unless an alloy sleeve is inside the frame. If you
mount a carbon seat post, do not put any grease on it, even
if the frame is made of metal. Once greased, carbon com-
ponents may never again ensure reliable clamping. Use
special carbon assembly paste instead
(h) .
A If the seat post does not move easily inside the seat tube
or if it cannot be tightened sufficiently, ask your WHEELER
bicycle dealer for advice! Do not use brute force!

ADJUSTING THE HEIGHT OF THE HANDLEBARS
The height of the handlebars compared to the saddle and the distance
between saddle and handlebars determine how much your upper body
will be inclined forward. Lowering the handlebars gives you a stream-
lined position and brings more weight to bear on the front wheel. How-
ever, it also entails an extremely forward leaning posture which is tiring
and less comfortable, because it increases the strain on your wrists,
arms, back, upper body and neck.
There are three different stem systems that allow vertical adjustment
of the handlebars, i.e. the conventional, the adjustable and the Ahead-
set® stem. These systems require special knowledge. In this regard,
the descriptions hereafter may be incomplete. If you are in doubt or if
you have any questions, then contact your WHEELER bicycle dealer.
G The stem is one of the load bearing parts of your bicycle.
Changes to it can impair your safety. If you are in doubt
or if you have any questions, then contact your WHEELER
bicycle dealer.
G Stems come in varying lengths
(a) as well as shaft and
binder tube diameters
(b) . A stem of inappropriate dimen-
sions can become a source of danger: Handlebars or stems
can break, resulting in an accident. When replacing any
parts be sure to only use parts that bear the appropriate
mark and, to be on the safe side, original spare parts. Your
WHEELER bicycle dealer will be pleased to help you.
G The bolted connections of stem and handlebars have to be
tightened to the prescribed torque values
(c) . If you dis-
regard the prescribed values, the handlebars or stem may
come loose or break. Use a torque wrench
(d) and never
exceed the maximum torque values! You can find these in
the chapter “Recommended Torque Settings for Compo-
nents”, on the components themselves and/or in the in-
structions from the parts manufacturers, which you can
find on the enclosed CD.
A Make sure the handlebar-stem combination is approved by
the handlebar and/or stem manufacturer.
A Check that the area of the stem where the handlebars are
clamped has no sharp edges.
CONVENTIONAL STEMS
Handlebars with conventional stems allow limited vertical adjustment.
This is done by moving the stem up or down inside the fork steerer tube.
Release the expander bolt by two to three complete turns. The stem
should now turn freely inside the fork. If it does not, release the bolt by
tapping it gently with a rubber hammer
(e) . With Allen bolts you need to
stick the Allen key into its head first, as it is normally countersunk and
therefore impossible to be hit directly.
Now you can move the handlebar/stem unit up and down as a whole.
Be sure not to pull out the stem too far. The mark on the stem (end,
min, max, stop, limit or the like) should always remain within the tube
(f) . Setting the stem to a lower position can only add to your safety!
Realign the handlebars with the front wheel
(g) . Retighten the expander
bolt with a torque wrench.
Tighten carefully by approaching the prescribed maximum torque in
small steps (0.5 Nm increments) and check in between the proper fit
of the component. Never exceed the maximum torque value indicated
by the manufacturer!
Make sure the stem is firmly fixed by taking the front wheel between
your legs and trying to turn the handlebars and stem relative to the
wheel
(h) . If there is movement, you have to increase the torque. If the
handlebars are still too high or too low, you can replace the stem. This
can be quite a big job, as it may mean taking off and remounting all
the fittings on the handlebars. Inform yourself at your WHEELER bicycle
dealer about the various stem types available.
G Never ride a WHEELER bicycle with a stem that has been
drawn out beyond the mark for the maximum permissible
height! Check all bolted connections and test your brakes
before you set off!
A Never try to unscrew the lock nut of the headset when you
only want to adjust the stem, as you will otherwise alter the
bearing play.

ADJUSTABLE STEMS
There are various solutions for adjusting the tilt of the front part of
adjustable stems
(a) :
Some designs use bolts on the sides of the joint
(b) , others have bolts
coming from above or below
(c) , and other again are equipped with
additional locking mechanisms or adjusting bolts.
Before adjusting read the enclosed operating instructions of the stem
manufacturer. Ask your WHEELER bicycle dealer to explain to you both
the function and adjustment of your stem or else let him do that work.
G Note that the bolted connections of adjustable stems and
handlebars have to be tightened to the specified torques.
Otherwise the handlebars or stem may come loose or
break. Use a torque wrench and observe the minimum and
maximum torque values! You can find these in the chapter
“Recommended Torque Settings for Components”, on the
components themselves and/or in the instructions from the
parts manufacturers, which you can find on the enclosed
CD.
a Keep in mind that readjusting the position of the stem
changes the position of the handlebars, brake and shift le-
vers. Readjust these components, as described in chapter
“Adjusting the Tilt of the Handlebars, Bar Ends and Brake
Levers”.
STEMS FOR THREADLESS SYSTEMS,
THE AHEADSET® SYSTEM
(Aheadset® is a registered trade mark of Dia-Compe)
In the case of bicycles with Aheadset® headsets the stem also serves
to adjust the bearing preload. If you change the position of the stem you
have to readjust the bearing play (see the chapter “Headset”).
The vertical setting range is determined by the intermediate rings, also
referred to as spacers
(d) . In the case of flip-flop stem models the stem
can be mounted the other way round to achieve a different handlebar
height.
Unscrew the preload bolt at the top of the fork steerer tube, remove the
cap and release the bolts on either side of the stem by up to three turns
(e) . Remove the stem and spacers from the fork steerer tube. In doing
so keep hold of both frame and fork to prevent the fork from slipping
off the head tube.
You can determine the handlebar height by the arrangement of stem and
spacers. Slip the remaining spacers onto the fork steerer tube above
the stem. Adjust the headset, as described in the chapter “Headset”.
If you want to turn the stem around, you have to also release the bolts
of the faceplate securing the handlebars
(f) . If the stem is fitted with
a cap, you can simply take out the handlebars at this point. If it is not
fitted with a cap, you have to remove the handlebar fittings.
Mount the handlebars and, if necessary, the handlebar fittings, as de-
scribed in the chapter “Adjusting the Tilt of the Handlebars, Bar
Ends and Brake Levers” and/or in the operating instructions of the
parts manufacturers, which you can find on the enclosed CD.
Check whether the handlebars are firmly seated in the stem by trying to
rotate the handlebars downwards. Verify whether the handlebar/stem
unit can be twisted relative to the fork. Do this by taking the front wheel
between your knees and trying to twist the handlebars
(g) . If there is
movement, carefully tighten the bolts a little more and check again the
proper fit.
Tighten carefully by approaching the prescribed maximum torque in
small steps (0.5 Nm increments) and check in between the proper fit of
the component
(h) . Never exceed the maximum torque value indicated
by the manufacturer!
G These routines require a certain amount of manual skill and
(special) tools and are best left to your WHEELER bicycle
dealer. If you still wish to do this by yourself, carefully read
through beforehand the instructions of the stem manufac-
turer, which you can find on the enclosed CD.
