6.5.5 Retracting the brake linings
Disc brakes require wearing-in time. The braking
force increases over time. You therefore need to be
aware that the braking force may increase during the
wearing-in period. The same happens after brake
pads or discs are replaced.
1 Accelerate pedelec to about 25 km/h.
2 Brake pedelec until it comes to a halt.
3 Repeat process 30–50 times.
 The disc brake is retracted and provides
optimal braking power.
6.5.6 Adjusting the Suntour fork
Only applies to pedelecs with this equipment
Brake failure due to incorrect setting
If the pressure point is set with brakes where the
brake linings and brake disc have reached their
wear limit, the brakes may fail and cause an
accident with injury.
 Before you set the pressure point, ensure that
the brake linings and brake disc have not
reached their wear limit.
WARNING
!
Crash caused by incorrectly set suspension
If the suspension is set incorrectly, the fork may
become damaged, meaning problems may occur
when steering. This will cause a crash with
injuries.

Never ride the bicycle without air in the air
suspension fork.

Never use the pedelec without adjusting the
suspension fork to the rider's weight.
Notice
Settings on the chassis change riding
performance significantly. You need to get used
to the bicycle and break it in to prevent accidents.
