7�6 The cranks, bottom bracket and pedals
Cranks and pedals can loosen and wear over time.
© Check your cranks and pedals regularly for any looseness. If in doubt, get them checked and tightened by
a mechanic.
© Damaged cranks and a hard-to-rotate or damaged bottom bracket will need to be repaired by a professional
and replaced if necessary.
7�7 The wheels and spokes
The spokes connect the hub of each wheel to the rims. They must be properly tensioned because they have an
influence on how the wheel rotates.
© Check the spokes regularly for damage and adequate tension or have them checked by a specialist.
© Have damaged spokes repaired by a professional and replaced if necessary.
© If a wheel has excessive lateral or vertical runout (more than 1 mm), have it repaired or trued by a professional.
7�8 Maintenance schedule
Having your woom bike regularly serviced is important for the safety of your child.
After 200 kilometers and at least once a year:
© Have the tires and wheels checked for soundness and proper condition.
© Have the tightening torques checked for the handlebars, headset, cranks, pedals, saddle, seatpost and all
bolted fastenings and connections.
Every 1,000 kilometers, get a professional mechanic to thoroughly inspect, clean, lubricate and, if necessary,
replace the following components:
Hubs, pedals, headset, brakes, gearing, chain and drivetrain components, tires and suspension fork.
7�9 Cleaning your woom bike
Clean your woom bike regularly to prevent damage and keep your child safe on the road. Do not use a high-pressure
washer as this may damage bearings and similar components. Never clean the bicycle with acids, cleaning agents
containing oil or liquids containing solvents.
Frame, handlebars, fork, wheels
Clean these components with warm water, mild detergent and a soft cloth or sponge.
Chain, cassette, front chainring
Clean these components with an oily cloth or with a cleaning agent suitable for chains and a brush. After cleaning
the chain, it should be oiled with a suitable lubricant (see section 7.2 The chain).
Brakes
If the brakes are very dirty, you can clean them with warm water and detergent. To clean the disc brake rotors, use
a brake cleaner designed for this purpose. Never use cleaning agents that contain oil.
