6.5.4.5 Adjusting the saddle 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.

The saddle setting must only be made when the
bicycle is stationary.

To adjust the saddle position 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.

Move the saddle within its permitted displace-
ment range only (marked on the saddle stay).
1 Climb onto the pedelec.
2 Place the pedals into the vertical position with
your feet.
 Pedelec riders are adopting the optimal saddle
position if the perpendicular line from the
kneecap runs through the pedal axle.
 If the perpendicular line crosses behind the
pedal, bring the saddle further forward.
 If the perpendicular line crosses in front of the
pedal, bring the saddle further back.

3 Unfasten and adjust the designated screw
connections, and clamp them with the
maximum tightening torque for the saddle
clamping screws.

6.5.4.6 Adjusting the saddle tilt

The saddle tilt must be adjusted to the seat height,
the saddle and handlebar position, and the saddle
shape to ensure an optimum fit. The seating
position can be optimised in this way if needed.
The saddle prevents pedelec riders from slipping
backwards or forwards when placed in a
horizontal position. This prevents seat problems.
In any other position, the tip of the saddle may
press uncomfortably into the crotch area. It is also
recommended that the centre of the saddle is
exactly straight. This ensures that the rider is
seated with their sit bones on the wide rear part of
the saddle.
1 Adjust the saddle tilt to horizontal.
2 Position saddle middle so that it is completely
straight.

of the saddle
 Pedelec riders sit comfortably on the saddle
and do not slip backwards or forwards.
3 Pedelec riders tend to slip forwards on the
narrow part of the saddle, adjust the riding
position (see Section 6.6.2.3) or tilt the saddle
very slightly backwards.

6.5.4.7 Checking saddle stability

 Check saddle stability after adjusting it
(see Section 7.5.13).
