Operation
6.21.4 Using a ROHLOFF gear shift
Only applies to pedelecs with this equipment
The grip shifter can be easily turned from detent
to detent when the bike is stationary or low force
is applied to the pedals. The manual force
required to turn the shift lever increases as the
pedal force intensifies.
 If you wish to change gear quickly in any crank
position, relieve the pressure on the pedal at
the exact moment you turn the shifter without
interrupting the pedalling motion.
 The amount of force applied determines how
smooth the shifting process is.
The pedalling force is reduced when the crank
passes through its dead centres. Shifting gears
when passing through a crank dead centre
therefore always ensures a low force is required
for shifting.
You turn the twist grip to shift gears with the
ROHLOFF gear hub.

indicator (2)
 Turn towards number 14 to switch up to higher
gear speeds.
 Turn towards number 1 to switch down to
slower gear speeds.
 Immediately after you turn to another gear
speed, the ROHLOFF gear hub switches a
gear higher or lower.
 When changing gears between 7 and 8 or 8
and 7, avoid shifting very slowly or while
applying great force to the pedals; otherwise,
you may shift to gear 11 or 14 briefly as an
intermediate gear.
Risk of falling if gear shift subject to high
pedal load
Shifting gears when applying great force to the
pedals produces a strong, shock-like impact load
on the coupling elements in the gear mechanism.
This can cause the crank to rotate unrestrictedly
temporarily due to the coupling elements
snapping back. The rider can lose their balance
and fall as a result.

Shift down in good time, e.g. before ascents,
and thus avoid shifting gears when pressing
hard on the pedals (e.g. going uphill).
