6.21 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.
 Stop pedalling briefly when changing gears.
This makes it easier to switch gears and
reduces wear on the drivetrain. However, keep
the crank moving while switching gears.
