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.

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.

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.
