How it works
In conjunction with <eBike Lock>, the smartphone
works in a similar way to a key for the drive unit.
The <eBike Lock> is activated by switching off the
eBike. As long as the <eBike Lock> is active after the
function is switched on, this will be indicated by
the LED Remote control unit flashing white and by a
padlock symbol on the on-board computer.
Note: <eBike Lock> alone does not provide ade-
quate theft protection; it is simply a supplement to a
mechanical lock. <eBike Lock> does not provide any
form of mechanical lock for the eBike. Only the assis-
tance from the drive unit is deactivated. As long as
the smartphone is connected with the eBike via
Bluetooth®, the drive unit is unlocked.
If you wish to give other users temporary or per-
manent access to your eBike or you want to take
your eBike to a service, you will need to deactivate
the <eBike Lock> in the eBike Flow app in
the <Settings> menu item. If you wish to sell your
eBike, you will also need to delete the eBike from
your user account in the eBike Flow app in the <Set-
tings> menu item.
When the eBike is switched off, the drive unit will
emit a "Lock" sound (i.e. an audio signal that is played
once) to indicate that the assistance from the drive
unit is switched off.
Note: The audio signal will only be played if the eBike
is switched on.
When the eBike is switched on, the drive unit will emit
two "Unlock" sounds (i.e. an audio signal that is
played twice) to indicate that the assistance from the
drive unit is enabled again.
The "Lock" sound helps you to recognize whether
<eBike Lock> is activated on your eBike. The audio

signal is activated by default, but it can be deacti-
vated in the eBike Flow app in the <Settings> menu
item by selecting the lock symbol under your eBike.
Note: If you are no longer able to set up or switch off
<eBike Lock>, please contact your bicycle dealer.

Software updates
Software updates must be started manually in the
eBike Flow app.
Software updates are transferred from the app to the
operating unit in the background as soon as it is con-
nected to the app. During the update process, the
green flashing of the battery charge indicator of the
eBike battery (3) indicates the progress. The eBike is
then restarted.
You can control the software updates via the eBike
Flow app.
