Suspension and damping can be adjusted to the
rider's weight in up to six increments, depending
on the suspension system.
Sequence Adjustment
1 Adjust the suspension fork sag
2 Adjust the rear frame damper sag
3 Adjust the suspension fork rebound damper
4 Adjust the rear frame damper rebound damper
5 Adjust the rear frame damper compression damper

6.5.12 Adjusting sag (fork)

CAUTION
!
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 without air in air suspension forks.
 Never use the pedelec without adjusting the
suspension fork to the body weight.
Adjustments on the chassis change ride
performance significantly. The rider needs to get
used to the pedelec and break it in to prevent
accidents.

Sag (also referred to as negative deflection) is the
percentage of the total deflection that is
compressed by the rider's body weight, including
equipment (such as a backpack), the seating
position and frame geometry. Sag occurs whether
you are actually riding or not.
The pedelec rebounds at a controlled speed if it is
optimally adjusted. The wheel stays in contact
with the ground when passing over bumps (blue
line). The fork head, handlebars and body follow
terrain (green line) when riding over bumps. The
suspension motion is predictable and controlled.
