Description
3.3.5 Saddle
The purpose of the saddle is to absorb body
weight, provide support and enable different riding
positions. The shape of the saddle thus depends
on the intended use of the pedelec and the rider’s
physique and posture.
When riding a pedelec, the rider's body weight is
distributed between the pedals, the saddle and
the handlebars. When the rider is an upright
positon, the relatively small saddle area bears
about 75% of the body weight. The seat area is
one of the most sensitive regions of the body. The
saddle should allow the rider sit free of pain and
fatigue.
3.3.6 Seat post
Seat posts are not designed to fasten the saddle
but also to adjust exactly to the optimum sitting
position. The seat post can:
• adjust the seat height in the seat tube
• adjust the saddle horizontally with a clamping
mechanism and
• adjust the saddle angle by swivelling the entire
saddle clamping mechanism.
Retractable seat posts feature a remote control on
the handlebars, which can be used to lower the
seat post at a traffic light, for example, and then
raise it again.
3.3.6.1 Patent seat post

one or two seat clamp screws
Patent seat posts have a rigid link between the
saddle and the post. Patent seat posts which are
angled more markedly towards the rear are offset
seat posts. Offset seat posts provide a greater
distance between the saddle and the handlebars.
In patent saddle posts, the saddle is attached to
the head with one or two seat clamp screws. It is
recommended to lubricate the thread in these
screws to ensure sufficient tension when
tightening the screw.
Patent saddle posts are fastened into the seat
tube with either a quick release or a screwable
clamp.
