If you do not reactivate walk assistance within 10 s, walk as-
sistance automatically switches off.
Walk assistance is always ended if:
– the rear wheel jams,
– the bicycle cannot move over ridges,
– a body part is blocking the bike crank,
– an obstacle continues to turn the crank,
– you start pedalling,
– the (9) button or on/off button (1) is pressed.
Walk assistance has a roll-away lock, i.e. even after walk as-
sistance has been used, rolling backwards is actively curbed
by the drive system for a few seconds, and you cannot push
the eBike backwards or can only do so with difficulty.
The push assistance function is subject to local regulations;
the way it works may therefore differ from the description
above, or the function may even be deactivated completely.
ABS – anti-lock braking system (optional)
If the bicycle is equipped with a Bosch eBike ABS, the ABS
LED (4) lights up when the eBike system starts.
After moving off, the ABS internally checks its functionality
and the ABS LED goes off.
In the event of a fault, the ABS LED (4) lights up, together
with the orange flashing assistance level LED (5). You can
acknowledge the error with the select button (2); the flash-
ing assistance level LED (5) goes out. While the ABS LED (4)
is lit up, the ABS is not in operation.
For details on the ABS and how it works, please refer to the
ABS operating instructions.

on/off button (1). Release the on/off button (1) as soon as
the topmost bar on the battery charge indicator shows the
pairing process by flashing blue.

you must be logged in as the user.

count on the eBike Flow app using another smartphone and
unlock then the eBike.

How it works
In combination with the <eBike Lock>, the smartphone
functions similarly to a key for the drive unit. The <eBike
Lock> is activated by switching off the eBike system. As long
as the <eBike Lock> is active after the function is switched
on, this will be indicated by the operating unit LED Remote
flashing white and by a padlock symbol on the display.
Note: The <eBike Lock> alone does not provide adequate
theft protection; it is simply a supplement to a mechanical
lock. The <eBike Lock> does not provide any form of mech-
anical lock for the eBike. Only the assistance from the drive
unit is deactivated. The drive unit will be unlocked for as long
as the smartphone is connected to the eBike via Bluetooth®.
