1. Preface
Welcome to the woom family!
Thank you very much for purchasing a woom bike. When used properly, this bike makes it
possible for your child to enjoy their bicycle experience.
Our woom bikes are tested, hiqh-quality products designed for children and teenagers
to provide the best possible companion for bicycling.
2. Safety information
2.1. Basic safety information
Your woom bike is shipped in a partially assembled state. Before the first ride, some work
is required to put your bike in usable condition. Follow the provided assembly instructions,
as well as section 3 of this manual, „Before your first ride“.
Bicycling is meant to be fun and is good for your health, if it is done properly and respon-
sibly. This manual will help you use your woom bike correctly and safely. Read the manual
completely through, and particularly pay attention to all of the warnings and maintenance
instructions before using the bike. If someone borrows the bike or guardians supervise your
child, make sure that they are also familiar with the content of the manual.
Warning! Maintenance!
2.2. Information for parents and guardians
As a parent or supervising legal guardian of a child, you are responsible for the activities
and safety of the child. Here is some advice on riding safely.

5
Helmet and clothing.
Get your child a suitable helmet and ensure that it is always used at any time when riding
a bicycle, and that the helmet is securely on the child’s head. The child should wear appro-
priate, closely fitting, bright and preferably reflective clothing so other road users can see
the clothing in a timely manner. Always use sturdy and non-slip footwear and appropriate
protective clothing for bicycling.
Teach your child how to woom correctly.
Make sure you explain to your child the function of the brakes in a comprehensible way,
and that the child has become familiar with the brakes before the first ride. Teach your
child safe and responsible handling of the bike’s brakes. This will help prepare them for
riding in various environments.
Monitor your child.
You know the skill level of your child best. Pay attention to what can be expected from him/
her when bicycling so that she/he is safe at all times. Pay attention to the surroundings of
your child, including external distractions, and do not let the child ride in direct proximity
to other small children.

The bicycle and its components include pointed and hard metal
objects that may cause injuries. In the event of a fall or crash, check
first if the child is okay. After any fall or crash on the bike, check the
bicycle and components for damages before you allow your child to
get back on the bike.
2.3. Safety in road trac
Make yourself knowledgeable about the applicable national regulations and explain to
your child the basic rules of the Road Trac Act. In Austria, Road Trac Act, especially
section VI. (§§65-69), and 146th Regulation/Bicycle Regulation are Warning Maintenance
3 applicable. In Germany, the applicable regulations are covered by the Road Trac Acts
StVZO and StVO. For Switzerland, the articles 213 to 218 of the applicable regulations on
technical requirements for road vehicles apply.
Avoid riding a bike during slippery and wet weather conditions. If unavoidable, you should
ride more slowly and carefully, and be constantly ready to use the brake(s). Make sure a
bike light is in use if you must ride in low-visibility conditions.

6
2.4. Proper use
For what and for whom is your woom bike suitable?
The woom bike is designed for common bicycling in a safe environment. The woom bike is
a children‘s bicycle that is tailored to the child’s weight of the intended specific age (de-
pending on the model). In case of carrying luggage on the luggage carrier, the permissible
weight limits (see underside of rack) must be observed.
Also, note that in case of intensive use of the bicycle, it will show wear
faster. Take care and maintain your woom bike regularly according
to the instructions in section 5, and follow the proposed inspection
plan in section 7.
What should be avoided?
Jumps, stunts, downhill and other extreme sports are not intended for the woom bike. The
frame as well as other components of the bicycle can fail during the use of the bicycle by
an adult.
The intended use also includes the observance of the operating, maintenance and servicing
conditions, which are described in this manual and in the installation instructions. woom
bikes and distributors are not liable for using the bike beyond its intended use.

7
3. Before the first and every ride
Before the first ride it is mandatory to put the bike in ready-to-use condition. Follow the
supplied assembly instructions and the torques needed for tightening the components in
section 8.2. Here you can find a detailed support for assembling the woom bikes in English:
https://www.youtube.com/watch?v=orWfMSsvtME.
Before the first and every ride, make sure that:
Saddle, handlebars and pedals have been fixed with the required strength.
The positioning of saddle and handlebar is appropriate for the height of your
child, and he/she can start and stop safely.
Brakes are working and the brake levers are easy and comfortable for your
child to reach.
Wheels are firmly located in the forks of the frame and turn easily.
Screws and other components are fastened tightly and the quick-release
levers are tightened.
Tires, rims and frame are free of damage and foreign objects.
Tires have adequate tread depth and there is sucient air pressure in the tire.

4.2. Frame
woom-frames are made of high quality aluminum tubes that are optimized for keep balance
easily. This is made possible by the frame structure allowing for an upright sitting position
and the standard built-in steering limiter of the woom 1, 1 PLUS, 2 and 3.
In the event that your bike is stolen, and for insurance matters, you
should make a note of the frame serial number. The frame number
clearly identifies your bicycle (woom 2–6). You can find this number
at the lower end of the seat tube (see picture).
Frame serial number:
4.3. Steering system – handlebar
The steering system consists of the handlebar, the handlebar stem and the headset.
The headset holds the fork in the frame, and allows for easy turning of the handlebars. It is
exposed to heavy loads during the ride, and therefore needs to fit properly. It must not
have any play and must be able to turn easily.
The ahead-stem used for the woom bike is the connecting piece between the headset and
the handlebar.
1. Hex screw at the lower end
of the stem: by loosening
this screw you can adjust the
handlebar at a right angle to
the front wheel set. Make
sure that the wheel is not
installed the wrong way
around– the brakes have to
be located in front of the
fork.
2. Hex screw on the front part of the stem: it allows the handlebar to turn on its own
axis (woom 1–3).
3. Hex screws on the Vario clamps: they allow the handlebar to turn on its own axis
(woom 4–6).

Make sure that the hex screws are not stripped or tightened too much.
Tighten screw by screw carefully and slowly at first, then tighten them
with the correct torque (see section 8.2).
4.4. Fork
The bicycle fork holds the front wheel and thus has an important function, which is important
for the safety of your child. The lightweight fork made by aluminum ensures the required
degree of shock absorption for your woom bike.
If you see any damage, bending or cracks on the frame or the fork,
never let your child continue riding, and do not repair any of these
components yourself.
4.5. Seat and sitting position
When the child is sitting on the seat, she/he should be able to touch the ground with both
feet and stand in a stable position.
The picture shows the seating position of a more advanced cyclist.
In this bicycling position, the seat is set so high that the leg is almost
stretched when the heel touches the pedal in the lowest position.
In this seat position, the child should have already learned how to
get on and o the seat.
There are two seat settings or adjustments:
Height: To set the height, use the quick-release lever (woom 3-6). Note the minimum
insertion depth of the seat into the frame tube.
Horizontal change: By loosening the two screws, you can move the seat to the rear and to
the front (woom 4, 5, 6). The seat should be as horizontal as possible.

11
4.6. Adjusting seat height (woom 1 – 2)
For the woom 1, 1 PLUS and 2 the height of the seat can
be adjusted by opening the seatpost clamp with a hex key.
4.7. Using the quick-release lever (woom 3 – 6)
The quick release consists of two parts, the adjusting
nut (1) and the clamping lever (2).
Opening: Turn the clamping lever to the limit stop,
so that you can see the inner side of the lever. To
loosen the quick-release device even more, turn the
adjustment nut counter-clockwise.
Closing: With open clamping leverin one hand, turn the adjusting nut in a clockwise direction
while holding the clamping lever with the other hand. Now tighten the nut. Then turn the
clamping lever using the palm of your hand in a manner that you can see the
outer side of the lever.
4.8. Pedals
The two pedals are marked with an Lor an R
at the screw retained end. The pedal marked
with R needs to be screwed into the right
crank, and then tightened clockwise. The
same needs to be done with the other pedal
on the opposite side of the crank, which has
to be tightened counter-clockwise.
4.9. Pedal cranks and bearings
Cranks connect the pedals to the bottom bracket, and enable the drive through the inter-
action of these components when you ride a bicycle.


Pedal cranks may become loose, therefore the correct positioning
of the crank should be checked on a regular basis. Hold both crank
arms with both hands and move the crank back and forth. If you
find out that they wobble, this means there is some damage. Even
bottom brackets may wear out after a certain period of time. If you
hear a cracking noise in the bottom bracket, have the bottom bracket
repaired by a specialist or have it replaced.
4.10.Derailleur
For the woom bikes 4, 5, 6 we use a high-quality SRAM Sx4 GripShift rotational handle
as the gear shift. You can change gears with it. After some time of using it, an adjustment
might be necessary.
Derailleur
The woom bikes 4, 5, 6 use a high-quality derailleur, the SRAM X4 Derailleur. Normally,
the setting of the derailleur has already been done before delivery.
If there are any problems with the gears due to an accident or another
occurrence, we’ll ask you to take the bike either to a bike store, or to
repair it yourself in case you are skilled enough to do some repairs
using the SRAM product manual.
4.11. Bicycle chain
The bike chain is subject to heavy strain,
and therefore has to have a certain tension.
The tension is ideal if the chain cannot be
pulled downwards in a way that is shown on
the first photo. If there is a creaking in the
bottom bracket due to fartoo much tension,
tension can be adjusted by moving the rear
wheel horizontally.

13
The chain must be regularly cleaned and greased. Clean the chain
first by using an oily piece of cloth, and then oil the clean chain with
a suitable lubricant.
4.12. Brakes and brake lever
With the woom bike,the front brake
is controlled by the left brake, the
rear brake by the right brake.
1. Adjustment screw brake cable
2. Mounting screw
3. Adjusting screw handle width
Some time after starting to use the brake and its regular use, you will notice some stretch-
ing of the brake cable. The adjustment screw serves the purpose of minimal adjustment.
Setting the range of the brake handle
With the help of the adjusting screw that goes into the brake lever, the handle range can be
adjusted. If required, the distance between the brake lever and the grip tap can be adjusted
by using a Philips screwdriver.

Your woom bike is delivered with a suitable default spacing for the
appropriate model. In the case of self-initiated changes make sure that
there is enough space between the brake levers and the handlebar.
The brake lever must not touch the handlebar grip, not even when
used heavily. The brake lever should be adjusted in a way that your
child can use the brake safely, without getting tired.
Set the correct angle of the brake lever by using the fixing screw. Turn the lever until the
hand forms a straight line with the forearm.

Brakes
Check the brake pads regularly for their quality. Brake pads need to
be replaced by new ones before reaching the wear mark. Both brake
pads must be replaced at the same time.
Brake pads must not get in contact with oil or fat. Well working brake
pads touch the outside of the rim, not the tires.
4.13. Wheels
The wheel has to sit firmly and centered in the frame or fork, and needs to rotate easily.
Use the quick-release (woom 4, 5 and 6) or a 5 mm hex key (woom 1, 1 PLUS, 2 and 3) for
fittings, to achieve the appropriate stability.
Rims wear embossed markings for wear of rims. After a certain period
of use, these will be visible. As soon as the markings show wear and
tear, don‘t allow your child to ride the bike with this rim or wheel
and have it replaced.
Rims are wear parts that are exposed to large loads. Deformed,
cracked, or broken wheels must be replaced immediately.
Spokes connect hubs with rims. They need to show a certain tension and have an influence
on the straightness of a wheel. Check the tension of the spokes regularly.
Check the profile, the air pressure and the condition of the tires
regularly. Replace worn-out tires immediately.

15
On the side of the tire, you will find the minimum or maximum
allowed airpressure forthe tire. In addition, the dimension of the tire is
marked. 50-403 means, for example, 50 mm tire width and 403
mm rim diameter.
woom exclusively uses car valves (Shrader valves). If you should decide to use dierent
kinds of valves during an inner tube exchange, familiarize yourself with the right way to
handle those.
5. Care and maintenance
Note maintenance information marked with the maintenance symbol in section 4, as well
as the suggested inspection plan in section 7.
For cleaning the bike, we recommend warm water and a sponge. If you use protection and
care products suitable for bicycles, pay attention to using them correctly, according to the
manufacturer’s instructions.
Never clean the bike using acids, grease, hot oil, brake cleaner, or
solvent-containing liquids. When riding in the rain, clean and lubricate
the gearshift, chain and brakes (except the brake surfaces!)
6. Quick fixes
6.1. Tire change
Front wheel:
First, unfasten the brake of the
front wheel. (This step doesn‘t
apply to woom 1.)
Pull o the cable connector of
the hub Dynamo (if it exists).
Then loosen the hex screws or

16
the quick-release skewer located on both sides of the fork and take the front
wheel o the fork.
Installation is done in reverse steps.
Back wheel:
Set the chain of the bike on the smallest sprocket.
Loosen the brake cable from its guidance to be able to take the wheel o
more easily.
Remove the Hebie chainguard (only woom 2/3).
Loosen the hex screws or the quick-release skewer on the shaft and take the
wheel out of the dropout.
Installation is as follows:
Set the chain on the smallest sprocket and put
the wheel in the dropout.
Make sure that the wheel sits in the socket, and
fasten the wheel with the Hex screws or with
the quick-release skewer.
In case of a woom 2 or3, the following number of
teeth has the be visible on the Hebie chainguard:
woom 2: 2 teeth, woom 3: 15 teeth (see image).
6.2. Brake is rubbing
The brakes are set and tested prior to shipping. If the brake shoes still rub on the rim loops,
this can be easily fixed. In order to adjust the brakes, there are four dierent options as
follows (see image). Due to the presetting of the brake,
we recommend to carry out fine adjustments using the
spring adjustment screw only (4):
1. Cable retainer screw: serves for the attachment
of the cable. By loosening the screw the brake
cable can be shortened or lengthened.
2. Screwfor adjustingthe brake pads: With this screw,
the brake pads and the 3 positioning to the rim
can be moved and set.
1
2 2
33
4 4

17
3. Screws for anchoring with the fork: to secure the brake arms to the fork.
4. Spring adjustment screw: to center the brake pads with the rim.
When adjusting the brake, we recommend turning the wheel after each modification and
checking the braking eect and performance.
In addition to the four bolts on the brake itself, there is still the possibility of changing the
tension of the brake cable with the help of the adjustment screw for brake cable (also see
4.12). If you would like to know more to set the brake, have a look at the following:
https://www.youtube.com/watch?v=kQT7OLkB5VI
6.3. Other common problems
The chain is rubbing First, try to lubricate the chain; should the problem continue,
adjust the derailleur correctly, or take it to a specialist.
The wheel is “wobbling”
A light „wobbling“ is common for new bicycles, this is often the
sidewall, and after a few km of riding, it disappears automatically.
If the wobbling is too much and the brakes are touched, you
should take the bicycle in for repair.
Unusual sounds while
riding
Make sure the chain is suciently lubricated, and is not stretched
too tightly. Again, tighten the screw at the bottom bracket
bearing and at the handlebar stem.
7. Inspection plan
Regular thorough inspections of the woom bikes by a skilled expert are extremely impor-
tant for the safety of your child. For this reason, we urgently recommend the following
inspection schedule:
After riding 200 km and at least once in a year, have the tires and wheels
checked for being undamaged and being in proper condition. Adjust the
tension of the brake cable, because it can expand after riding the new bike.
Have the gearshift adjusted, as well as the tightening torques on handlebars,
steering system, cranks, pedals, seat, seatpost and all mounting screws.

18
After 300 to 500 km have the brake pads, bicycle chain, pinion, sprocket and
rims checked for wear, and also check the tightness of all fittings.
Every 1000 km an expert should disassemble, inspect, clean, lubricate, and if
necessary, replace the following components: hubs, pedals, steering system,
brakes and gear shift.
8. Technical data
8.1. Weights and geometry data
