Final check
All electric wires must be laid in a manner which prevents them from bending or getting pulled
during all spring deflection movements and which adequately protects them against rubbing.
After completing the work, check that all components and screws are tight and functioning
correctly. Also check the rear wheel's freewheel and the functionality of the brake system.
Afterwards, a test drive must be carried out! After completing the test drive, the tightness of all
screw connections must be checked, as well as the adequate free travel of all moving parts. Re-
test the rear wheel's freewheel and check the brake system for overheating.
