Options for switching off the eBike system:
– Press the On/Off button 5 of the on-board computer.
– Switch the eBike battery pack off by its On/Off button (see
battery pack operating instructions).
– Remove the on-board computer out of its holder.
If the eBike is not moved and no button is pressed on the on-
board computer for 10 minutes, the eBike system will shut
down automatically in order to save energy.
eShift (optional)
eShift is the integration of automatic gear shifting systems in-
to the eBike system. To support the rider in the best way pos-
sible, the function indications and the basic settings menu
have been adapted for the "eShift" function.
eShift with NuVinci H|Sync
The optimum gear for the respective speed is automatically
set according to a pre-defined desired cadence. In manual
mode you can choose between multiple gears.
In the " NuVinci Cadence" mode you can use the "–" or
"+" button on the operating unit to increase or decrease the
desired cadence. If you hold down the "–" or "+" button, the
cadence will increase or decrease in steps of five. The desired
cadence is shown on the display.
In the " NuVinci Gear" mode you can use the "–" or "+"
button on the operating unit to switch back and forth between
several defined transmission ratios. The engaged transmis-
sion ratio (gear) is shown on the display.
eShift with SRAM DD3 Pulse
The gear hub of the SRAM DD3 Pulse works on a speed-de-
pendent basis. Regardless of which gear is engaged on the de-
railleur gears, one of the three gears of the gear hub will auto-
matically be engaged " Gear: Auto".
The engaged gear will be shown briefly on the display whenev-
er the gear of the gear hub is shifted.
If the eBike is brought to a standstill from a speed of more
than 10 km/h, the system can automatically switch back to a
set "Start gear". The "Start gear" can be set in the basic set-
tings menu (see "Displaying/Adapting Basic Settings" on page
English–6).
In the " Gear" mode you can use the "–" or "+" button on
the operating unit to switch back and forth between several
defined transmission ratios. The engaged transmission ratio
(gear) is shown on the display.
In the " Gear" manual mode, the system can also automati-
cally switch back to a set "Start gear".
The drive unit recognises the gear shift and briefly reduces
the motor assistance level as a result of it, which means the
gear can also be shifted at any time under load or on a hill.

Displays and configurations of the on-board
computer
Energy supply of the on-board computer
If the on-board computer is in the holder 4, a sufficiently
charged battery pack is inserted in the eBike and the eBike
system is turned on, then the on-board computer is powered
by the battery pack of the eBike.
If the on-board computer is removed from the holder 4, the
energy is supplied via an internal battery pack. If the internal
battery pack is weak when the on-board computer is switched
on, "Attach to bike" will appear in text indication d for 3 s.
The on-board computer will then turn off again.
To charge the internal battery pack, put the on-board comput-
er back in the holder 4 (when a battery pack is inserted in the
eBike). Switch the eBike battery pack on by its On/Off button
(see battery pack operating instructions).
You can also charge the on-board computer via the USB port.
Open the protective cap 8. Connect the USB port 7 of the on-
board computer via a suitable USB cable to a standard USB
charger or the USB port of a computer (5 V charging voltage,
max. 500 mA charging current). "USB connected" will ap-
pear in text indication d of the on-board computer.
 If you do not use your eBike for several weeks, remove
the on-board computer from its holder. Store the on-
board computer in a dry environment at room tempera-
ture. Regularly recharge the on-board computer's battery
pack.
Switching on/shutting down the on-board computer
To switch on the on-board computer, briefly press the On/Off
button 5. The on-board computer can also be switched on
when it is not inserted in the holder (if the internal battery
pack is sufficiently charged).
To switch off the on-board computer, press the On/Off but-
ton 5.
If the on-board computer is not inserted in the holder, it auto-
matically switches off after 1 minute to save energy if no but-
ton is pressed.
