I. Adjusting quick release mechanisms
Quick- release mechanisms hold the wheels in place, clamping them to the frame or fork. For the system to work effectively, you
need to adjust the adjusting nut (1) until the closing force on the quick release lever (2) is at least 12 daN (approximately 12 kg). To
increase the closing force: turn the adjusting nut clockwise and anticlockwise to decrease.
Comment: if in doubt, ask the advice of a qualified, experienced mechanic.
J. Fixing, adjusting and removing stabilizers on children's bikes
The stabilizers must be attached and adjusted as
follows:
Warning: Never attach or remove stabilizers by
removing other bike parts (e.g. wheel nuts).
To ensure the child's safety, it is essential that you
observe the recommendations for attaching and
adjusting stabilizers (height of wheels in relation
to ground etc.). Never use the bike with just one
stabilizer. Use a bike fitted with stabilizers on flat
ground.
