Adjusting the suspension of the
Suntour fork
Only applies to pedelecs with this equipment
The following Suntour forks can be installed in this
series of models:
The adjustment shown here represents a basic
setting. The rider should change the basic setting
to suit the surface and his/her preferences.
It is advisable to make a note of the basic
setting. This way, it can be used as the starting
point for subsequent, optimised settings and to
safeguard against unintentional changes.
6.6.5.1 Adjusting the negative deflection
Negative deflection (sag) is compression of the
fork caused by the weight of the rider and their
gear (e.g. a backpack), the sitting position and the
frame geometry. This sag is not caused by riding.
Each rider has a different weight and sitting
position. The sag depends on the rider's position
and weight and should be between 15% and 30%
of the maximum fork deflection, depending on
pedelec usage and preferences.
6.6.5.2 Adjusting the air suspension fork
negative deflection
Only applies to pedelecs with this equipment
The air valve is located under a cover on the
head of the left shock absorber. Screw off the
cover.
Figure 55: Screw caps in different designs
Screw a high-pressure pump onto the valve.
Pump the suspension fork up to the desired
pressure. Never exceed the recommended
maximum air pressure. Comply with the values
of the filling pressure table.
Remove the high-pressure pump.

Crash caused by incorrectly set suspension
If the suspension is adjusted incorrectly, the fork
may become damaged, so that problems may
occur when steering. This will cause a crash with
injuries.
Never ride the pedelec 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 pedelec and break it in to prevent
accidents.
