Operation
7.8 Gear shift
The selection of the appropriate gear is a prerequisite
for a physically comfortable ride and making sure that
the electric drive system functions properly. The ideal
pedalling frequency is between 70 and 80 revolutions
per minute.
It is advisable to stop pedalling briefly when
changing gears. This makes it easier to switch
gears and reduces wear on the drivetrain.
