6.15.2 Using a hub gear
Only applies to pedelecs with this equipment
CAUTION
!
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. As a result, the pedelec may flip
over or fall, which may cause injury.
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.
Do not detach the hub. If you need to detach it,
contact your dealer.

6.15.3 Use eShift
eShift refers to the integration of electronic gear
shift systems into the pedelec system.
6.15.3.1
eShift with Shimano DI2 automatic
hub gears
Only applies to pedelecs with this equipment
You can operate the automatic Shimano DI2 hub
gears in manual mode or automatic mode. You
used the gear shift to change gears in manual
mode. In automatic mode, the shift system
changes gear automatically depending on the
speed, pedalling power and pedalling frequency.
You will find how to switch from automatic to
manual mode, depending on the shifter used,
described in your operating instructions for your
gear shift.
If you use the shifter when in automatic mode, the
gear system will change to the next gear, but it will
remain in automatic mode.
Manual gear changes in automatic mode
influence shift behaviour in your gear system and
adjust gear changes to your riding performance
since it is a self-learning system.
If the system is switched on for the first time when
a new, unused wheel is used, the system will learn
the gears first. To do so, the automatic system
changes to the highest/most difficult gear and
then switches through all gears during the first
ride. The new gear is shown briefly on the screen
each time it is changed.
Since the drive unit detects the gear shift and
consequently reduces motor assistance briefly, it
is also possible to switch gears under load or on
hills.
If the pedelec is brought to a halt from a speed
greater than 10 km, the system can automatically
switch back to a pre-set S T A R T G E AR .
You can set the S T AR T G E A R in the system
settings.
