Figure 30: Open belt system with fleece hook-and-
loop straps for adjusting the slack
Note:
Using a seat cushion on the seat system is
mandatory. At cold temperatures, the seat
cushion prevents lower abdomens from under-
cooling and protects against dirt and wetness.
Moreover, the cushion ensures uniform pres-
sure distribution for your bottom and absorbs
impacts as well as vibrations.

19.1 Removing and attaching the drive
wheels
Figure 31: Locking knob of the quick-release axle in
the middle of the wheel axle
To
remove the drive wheels
grip through the
spokes around the wheel hub with your fingers.
The wheels can be unlocked and removed by
pressing and holding the locking knob at the
centre of the wheel axle with your thumb.
To
attach the drive wheels
, press the locking
knobs and insert the drive wheels with quick-
release axle into the drive wheel bushings.
When doing this, special attention should be
paid to ensure that the locking knob springs
out again after attaching the wheel, as other-
wise the wheels are not properly secured. You
will know this if you can see the index groove.
