Suspension; Fork Sag - Bosch ZEMO SU-E FS 12 Translation Of Original Operating Instructions

6.5.12 Suspension

A pedelec's fork suspension and rear frame
damper suspension 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 suspension fork rebound damper
4 Adjust rear frame damper rebound damper
5 Adjust the rear frame damper compression adjuster
6 The fork compression adjuster is adjusted to the terrain
while riding.

6.5.13 Fork sag

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 the bicycle without air in the air
suspension fork.
 Never use the pedelec without adjusting the
suspension fork to the rider's 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.
The sag depends on the position and rider's
weight and should be between 10% and 30% of
the maximum fork deflection, depending on
preferences and on how the pedelec is used.

 Follow the correct order for adjustment.

Greater sag (20%...30%)
A greater sag increases sensitivity to bumps, thus
producing greater suspension motion. A greater
sensitivity to bumps ensures more comfortable
ride performance and is used on pedelecs with a
longer deflection.
Decreased sag (10%...20%)
A decreased sag reduces sensitivity to bumps,
thus producing less suspension motion. A lower
sensitivity to bumps ensures a firmer, more
efficient ride performance and is generally used
on pedelecs with a shorter deflection.
The adjustment shown here represents a basic
setting. The rider should change the basic setting
to suit the surface and their preferences.
It is advisable to make a note of the basic settings.
These can then be used a starting point for
subsequent optimised settings and as a
safeguard against unintentional changes.
