Setting the Assistance Level
With the on-board computer you can set how much the
eBike drive assists you while pedaling. The assistance level
can be changed at any time while the system is on, even
while cycling.
Note: For individual versions, it is possible that the assis-
tance level is preset and cannot be changed. It is also pos-
sible 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 and the
eBike can be moved by pedaling. The walk assistance
cannot be activated in this assistance level.
– “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
The selected motor output appears on the display of the on-
board computer. The maximum motor output depends on
the selected assistance level.
Once it is switched on, the eBike system is in the “OFF”
mode.
Switching the Walk Assistance On/Off
The walk assistance can make it easier for you to push the
eBike. The speed of this function depends on the selected
gear and can reach a maximum of 3.7 mph. The lower the
selected gear, the lower the speed of the walk assistance
function (at full capacity).

Using the walk assistance function is only recom-
mended when pushing the eBike. There is risk of injury
if the wheels of the eBike are not in contact with the
ground while using the walk assistance.
To activate the walk assistance function, briefly press but-
ton “WALK” on your on-board computer. After activation,
press button “+” within 3 s and keep it pressed. The eBike
drive is switched on.
Note: The walk assistance cannot be activated in the “OFF”
assistance level.
The walk assistance is
switched off as soon as one of the
following occurs:
– you release the button “+” ,
– 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.
Switching bike lights On/Off
On the version which has bike lights powered by the eBike
system, the front and rear lights can be switched on and off
at the same time via the on-board computer.
Assistance Level Assistance Factor* (Derailleur)
“ECO” 55 %
“TOUR” 120 %
“SPORT” 190 %
“TURBO” 275 %
* The motor output can vary for individual versions.

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 bicy-
cle inspection, maintenance or repair can lead to seri-
ous injury.

If you suspect that something is loose, do not ride your
bike. See your Bosch eBike dealer; only a qualified ser-
vice provider should perform work on your Bosch Drive
System. All nuts, bolts, screws require the correct tight-
ening 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.

If replacing your battery, only buy a genuine Bosch
battery pack from an approved source. See your
Bosch eBike dealer for original Bosch parts.

Always switch the battery pack off when inserting or
removing it from the holder. Never attempt to insert or
remove the battery pack while riding the bike.

Do not charge or use your eBike in any area with a po-
tentially explosive atmosphere, such as at a fueling
area, or in areas where the air contains chemicals or
particles (such as grain, dust, or metal powders).
Obey all signs and follow all instructions.

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.

Note down the manufacturer and the number of the
key. In case the keys are lost, please contact an autho-
rized Bosch eBike dealer. Please provide the name of
the manufacturer and the number of the key.

Do not paint any components of the Bosch Drive Sys-
tem as this may cause premature failure of the com-
ponents.
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).
Please contact an authorized bicycle dealer for service or
repairs to the eBike.
After Sale Service and Customer Assistance
