6.5.3.6 Selecting the saddle hardness

Saddles are available in a wide range of
hardnesses and must be adapted to the pedelec's
use:
• A pedelec that is mainly used for commuting in
jeans calls for a soft saddle.
• A pedelec that is mainly used for sporty riding with
padded cycling shorts requires a hard saddle.
If the degree of hardness is not suitable, a new
saddle must be selected.
