Operation
6.17 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.
6.17.1 Using the derailleur gears
Only applies to pedelecs with this equipment
The speed and range can be increased while
applying the same force if you select the right
gear. Use the derailleur gears.

Crash caused by incorrect use
If the rider applies too much pressure on the
pedals during a gear change and activates the
shifter or changes several gears at a time, their
feet may slip from the pedals. This may cause a
crash or flip-over with injuries.
Switching down several gears to a low gear may
cause the twist grip outer sleeve to suddenly
come off. This will not have an adverse effect on
the twist grip's correct functioning since the outer
guide returns to its original position after the gear
change is complete.
 Apply little pressure on the pedals while
changing gears.

Never change more than one gear at a time.
Notice
The interior hub is not completely waterproof. If
water gets into the hub, it may rust and the gear
switch function may no longer function as a result.
 Never use the pedelec in places where water
may get into the hub.
In rare cases, noises may be heard from the rear
derailleur in the hub interior after a gear change.
This is normal when gears are changed.

Never detach the hub yourself. Contact your
specialist dealer.
