Operation
6.5.3.3 Adjusting the saddle height

To adjust the saddle height safely, either:
• Push the pedelec near to a wall so that the
pedelec rider can lean on the wall to support
themselves or
• Ask another person to hold the pedelec.
1 Use the seat height formula to roughly set the
saddle height:
Seat height (
SH ) = inner leg length ( I ) × 0.9
2 Climb onto the bicycle.
3 Place your heel on the pedal and extend your
leg, so that the pedal is at the lowest crank
rotation point. Your knee should now be fully
extended.
Figure 108: Heel method
4 Take a test ride.

Pedelec riders sit straight on the saddle at an
optimal saddle height.
• If the pelvis moves to the left and right as you
pedal, the saddle is too high.
• If your knees are painful after a few kilometres,
the saddle is too low.
 Position the seat post according to needs if
necessary. Adjust the seat height with the
quick release.
5 Open the quick release on the seat post to
change the seat height (1). To do so, push the
clamping lever away from the seat post (3).

6 Set the seat post to the required height.

the minimum insertion depth marking
7 To close it, push the seat post clamping lever as
far as it will go into the seat post (2).
8 Check the clamping force of the quick releases .
Crash caused by an excessively high seat post
setting
A seat post which is set too high will cause the
seat post or the frame to break. This will cause a
crash with injuries.

Do not pull the seat post out of the frame
beyond the minimum insertion depth marking.
