Description
3.3.5 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 traffic lights, for example, and then
raise it again.
3.3.5.1 Patent seat post
Figure 36: Example of ergotec patent seat post with either
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.

3.3.5.2 Suspension seat post
Suspension seat posts can reduce shock after
one-time hard impacts, thus improving ride
comfort significantly. However, suspension seat
posts are not able to compensate for bumps in the
road.
If the seat post is the only suspension element,
the entire pedelec is a non-suspended mass. This
has an unfavourable effect on loaded touring
bikes or pedelecs with child trailers.
Suspension seat posts feature small, heavy-duty
slide bearings, guides and articulated joints. If
they are not lubricated on a regular basis, the
sensitive response behaviour diminishes
considerably, causing excessive wear.
