6.5.1.5 Adjusting the seat position

The saddle can be shifted on the saddle frame.
The right horizontal position ensures an optimal
leverage position for legs. This prevents knee
pain and painful incorrect pelvis positions. If you
have displaced the saddle more than 10 mm, you
need to adjust the saddle height again since both
settings affect one another.

To adjust the seat position safely, either push the
pedelec near to a wall, so that you can lean on the
wall to support yourself or ask another person to
hold the pedelec for you.
1 Climb onto the bicycle.
2 Place the pedals into the vertical position with
your feet.
The rider is sitting in the optimal sitting position if
the knee cap perpendicular line runs through the
pedal axle.
3.1If the perpendicular line crosses behind the
pedal, bring the saddle forward.
3.2If the perpendicular line crosses in front of the
pedal, bring the saddle back.
4 Move the saddle within its permitted
displacement range only (marked on the
saddle stay).


The handlebar settings must only be adjusted
while the pedelec is stationary.
 Unfasten and adjust the designated screw
connections, and clamp them with the
maximum tightening torque for the clamping
screws of the handlebars.

Adjusting the handlebars

CAUTION
!
Crash caused by incorrectly set clamping
force
Excessively high clamping force will damage the
quick release and cause it to lose its function.
Insufficient clamping force will result in
unfavourable transmission of force. This can
cause components to break. This will cause a
crash with injuries.
 Never fasten a quick release using a tool (e.g.
hammer or pliers).
 Only use the clamping lever with the specified
set clamping force.

Adjusting the stem

6.5.3
CAUTION
!
Crash caused by loose stem
Incorrectly fastened screws may come loose due
to impact. The stem may no longer be firmly fixed
in its position as a result. This will cause a crash
with injuries.
 Check the handlebars and the quick release
system are firmly in position after the first two
hours of riding.
