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 using its On/Off

button (see battery pack operating instructions.)

– Remove the on-board computer out of its holder.

eShift (optional)

eShift is the integration of automatic gear shifting systems
into the eBike system. To support the rider in the best way
possible, 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
transmission ratio (gear) is shown on the display.

eShift with SRAM DD3 Pulse

The gear hub of the SRAM DD3 Pulse works on a speed-de­pendent basis. Regardless of which gear is engaged on the
derailleur gears, one of the three gears of the gear hub will
automatically be engaged (“ Autom. Gear Selection”).

The engaged gear will be shown briefly on the display when­ever the gear of the gear hub is shifted.

If the eBike is brought to a standstill from a speed of more
than 6 mph, the system can automatically switch back to a
set “Start gear”. The “Start gear” can be set in the basic
settings menu (see “Displaying/Adapting Basic Settings”
on page English–10).

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 auto-
matically switch back to a set “starting gear”.

The drive unit recognizes 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.

eShift with Shimano Di2

For Shimano eShift you use the Shimano control lever to
shift gears.

The engaged gear will be shown briefly on the display when­ever the gear of the gear hub is shifted.

The drive unit recognizes 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.

If the eBike is brought to a standstill from a speed of more
than 6 mph, the system can automatically switch back to a
set “Start gear”. The “Start gear” can be set in the basic
settings menu (see “Displaying/Adapting Basic Settings”
on page English–10).

Indications and Settings 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 into the eBike and the
eBike system is turned on, then the on-board computer is
powered by the eBike battery pack.

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 com­puter 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 con-
nected” will appear in the text indication d of the on-board
computer.

Switching the on-board computer On/Off

To switch on the on-board computer, briefly press the
On/Off button 5. When the internal battery pack is suffi­ciently charged, the on-board computer can also be
switched on when not inserted in the holder.

To switch off the on-board computer, press the On/Off
button 5.

When the on-board computer is not inserted in the holder
and no button is pressed, it automatically switches off after
1 min to save energy.

 If you do not use your eBike for several weeks, re-

move the on-board computer from its holder. Store

the on-board computer in a dry environment at room
temperature. Regularly recharge the on-board comput­er’s battery pack.

Battery charge-control indicator

The battery pack charge-control indicator i indicates the
charge condition of the eBike’s battery pack, and not the
charge condition of the on-board computer’s internal bat­tery. The charge condition of the eBike’s battery pack can
also be read from the battery pack’s LEDs.

On indicator i, each bar of the battery pack symbol is equiv­alent to a capacity of approx. 20 %:

Once there are no remaining LED bars illuminated
on the charge-control indicator, the motor support
is gently switched off and the charge-control indica­tor begins to flash. The flashing charge-control indi­cator means there is only enough battery power re­maining to power the eBike lights for approximately
2 more hours. This does not account for other con­sumers (e.g., automatic gearbox, charging external
devices at the USB port).

When the on-board computer is removed from holder 4,
the last indicated battery pack charge condition is stored.

If an eBike is operated with two battery packs, the battery
charge-control indicator i displays the level of both battery
packs.

If an eBike has two battery packs being
charged on the bike, the charging progress of
both battery packs will be indicated on the
display (the left-hand battery pack is being
charged in the illustration). You can tell by
the flashing indicator on the battery pack
which of the two battery packs is being
charged.

Setting the Assistance Level

The level of assistance of the eBike drive unit when pedal­ing can be adjusted via the operating unit 10. The assis­tance level can be changed anytime, even during riding.

Note: For individual versions, it is possible that the assis­tance level is preset and cannot be changed. It is also pos­sible that fewer assistance levels are available for selection
than listed here.

The following assistance levels (max.) are available:
– “OFF”: The motor assistance is switched off, the eBike

can be operated as a normal bicycle through pedaling.

– “ECO”: Effective assistance at maximum efficiency for

maximum cruising range

– “TOUR”: Uniform assistance, for touring with long cruis-

ing range

– “SPORT”: Powerful assistance for sporty off-road rid-

ing, as well as for urban traffic

– “TURBO”: Maximum assistance, supporting the highest

speed for sporty riding

To increase the assistance level, press the “+” button 13
on the operating unit until the desired assistance level is
displayed in indicator b; to decrease the assistance level,
press the “–” button 12.

The requested motor output is displayed in indicator a. The
maximum motor output depends on the selected assis­tance level.

When the on-board computer is removed from the holder
4, then the last indicated level is not stored and the on­board computer is reset to the “OFF” mode.

Once it is switched on, the eBike system is in the “OFF”
mode.

Interaction of the eBike System with the Bicycle Gears

The bicycle gears should be used as with a normal bicycle,
even with eBike motor assistance (please follow the operat­ing instructions for your eBike).

Independent of the type of gearing, it is recommended to
briefly interrupt the pedaling while changing gears. This
makes changing gears easier and reduces the wear on the
drive train.

By selecting the right gear, you can increase the speed and
range with the same pedaling effort.

For this reason, follow the shift recommendations provided
by indications g and h on your display. If indication g is dis-
played, you should shift to a higher gear with lower ca­dence. If indication h is displayed, you should select a lower
gear with higher cadence.

Switching bike lights On/Off

If your lights are set up to be powered by the eBike system,
then you can use the 2 button on the on-board computer to
simultaneously switch both the front light and the rear light
on and off.
When the lighting is switched on, “Lights on” appears, and
when the lighting is switched off, “Lights off” appears for
approx. 1 s in the text indicator d. The light symbol c is dis­played when the light is on.

Switching the driving light on and off has no effect on the
backlighting for the display. The backlighting for the display
is active as soon as the system or the display is switched on.

assistance level.

The walk assistance is switched off as soon as one of the
following occurs:
– you release the button “+” 13,
– the wheels of the eBike are stopped (e.g. by actuating

the brakes or impacting against an obstacle),

– the speed exceeds 3.7 mph.
Note: On some systems the walk assistance function can

be started directly by pressing the “WALK” button.

Power Supply for External Devices via USB Con­nection

With the USB connection, it is possible to operate and
charge most devices whose power supply is possible via a
USB port (e.g., various mobile phones).

A prerequisite for the charging is that the on-board comput­er and a sufficiently charged battery pack are inserted in
the eBike.

Open the protective cap 8 of the USB port on the on-board
computer. Connect the USB connection of the external de­vice to the USB port 7 on the on-board computer using the
USB charging cable Micro A – Micro B (available from your
Bosch eBike dealer).

Once the consumer has been disconnected, the USB con­nection must be sealed again carefully with the protective
cap 8.

 A USB connection is not a waterproof plug-in connec-

tion. When riding in the rain, an external device must
not be connected and the USB connection must be
completely sealed with the protective cap 8.

Transport

 If you carry your eBike outside of your car, e.g. on a

luggage rack, remove the on-board computer and
the eBike battery pack in order to avoid damaging
them. (If the on-board computer cannot be fitted onto a

bracket, it is not possible to remove it from the bicycle.
In this case, the on-board computer may remain on the
bicycle.)

 Always remove the battery pack from the bicycle be-

fore transporting the bicycle on a vehicle bike rack.

Failure to remove the battery pack when using a vehicle
bike rack can lead to death or serious injury. The battery
may detach during transport and cause an accident to
following vehicles.

 Always use an approved and compatible bicycle rack

when transporting your eBike. The Bosch Drive Sys­tem adds weight to the bicycle. Refer to your bicycle

rack manual to be sure your eBike is compatible. Over­loading a bike rack can result in death or serious injury.

 Use proper lifting techniques because electric bikes

are generally heavier than bicycles.

Ship batteries only when the housings are undamaged.
Tape or mask off open contacts and pack up the battery in
such a way that it cannot move around in the packaging. No­tify your parcel service that the package contains danger­ous goods. Please also follow possibly more detailed na­tional regulations. Always check the state and federal
regulations before attempting to ship your battery.

In case of questions concerning transport of the battery
packs, please contact an authorized Bosch eBike dealer.
Bosch eBike dealers can also provide suitable transport
packaging.

Maintenance/Cleaning

 Your Bosch Drive System components are mainte-

nance-free. Do not open any of the components. Ser-

vice should only be carried out at an authorized Bosch
eBike dealer. Failure to follow the above warning may
result in death or serious injury. Refer to your bicycle
manual or component manual for all non-Bosch Drive
System components.

 Always remove the battery pack before performing

any bicycle inspection, maintenance or repair. Fail-

ure to remove the battery pack before performing bicy­cle inspection, maintenance or repair can lead to seri­ous injury.

 If you suspect that something is loose, do not ride

your bike. See your Bosch eBike dealer; only a qualified

service provider should perform work on your Bosch
Drive System. All nuts, bolts, screws require the correct
tightening force. Too little force and the fastener may
not hold securely. Too much force and the fastener can
stretch, deform or break, or the threads can be
stripped. Either way, incorrect tightening force can re­sult in component failure, which can cause you to lose
control and fall.

 Do not paint any components of the Bosch Drive Sys-

tem as this may cause premature failure of the com­ponents.

Careful Handling of the eBike

Please observe the operating and storage temperatures for
the eBike components. Protect the drive unit, on-board
computer and battery pack against extreme temperatures
(e.g., from intense sunlight without adequate ventilation).
The components (especially the battery pack) can become
damaged because of extreme temperatures.

It is recommended to have your eBike system checked by
an expert at least once a year (including mechanical parts
and to update the system software).

The eBike manufacturer or dealer may also base the service
date on the distance traveled and/or a period of time. In this
case, the on-board computer will show you every time it is
switched on that the service date is due in the text indica­tion d by displaying “ Service” for 4 s.

Please contact an authorized bicycle dealer for service or
repairs to the eBike.

Cleaning

 Do not submerge your eBike components in water,

or wash using a pressurized hose. Your Bosch drive

unit is designed to be water tight in regards to rain water
and non-pressurized hose washing.

Keep all components of your eBike clean, especially the
battery pack contacts and the corresponding holder con­tacts.

All components including the drive unit may not be im­mersed in water or cleaned with a high-pressure cleaner.
Keep all components of your eBike clean, especially the
battery pack contacts and the corresponding holder con­tacts. Clean them carefully with a soft, damp cloth (using
only mild soap and water).

After Sale Service and Customer Assistance

In case of questions concerning the eBike system and its
components, please contact an authorized Bosch eBike
dealer.

Contact data for authorized Bosch eBike dealers can be
found at www.bosch-ebike.com

When the battery pack is no longer operative, please con­tact an authorized Bosch eBike dealer.
