Inserting and removing the on-board computer
(see figures A–B)
To insert the on-board computer (5), first fit the lower part
into the holder (4) and then press it forward until you can
feel the on-board computer engage. Ensure that the on-
board computer is firmly engaged.
To remove the on-board computer (5), press the release
mechanism (9) and remove the on-board computer up-
wards.
Remove the on-board computer when you park the
u
eBike.
It is possible to block the release mechanism with a screw.
To do so, remove the holder (4) from the handlebars. Place
the on-board computer in the holder. Screw the enclosed
locking screw (18) (M3 thread, 5 mm long) from below into
the thread provided in the holder. Fit the holder back onto
the handlebars.
Please note: The locking screw is not designed to prevent
theft.
Operation
Starting up the eBike system
Requirements
The eBike system can only be activated when the following
requirements are met:
– A sufficiently charged eBike battery is inserted (see oper-
ating instructions for the battery).
– The on-board computer is properly fitted in the holder.
– The on-board computer battery must be sufficiently
charged.
Switching the eBike system on/off
The following options are available for switching on the
eBike system:
– Once the on-board computer and the eBike battery are
fitted, briefly press the on/off button (3) on the on-board
computer.
– With the on-board computer inserted, press the on/off
button on the eBike battery (bicycle manufacturer-spe-
cific solutions are possible when there is no access to the
battery on/off button; see the operating instructions from
the bicycle manufacturer).
The drive is activated as soon as you start pedalling (except
if you are using the push-assistance function or if the assist-
ance level is set to OFF). The motor output depends on the
settings of the assistance level on the on-board computer.
Bosch eBike Systems
As soon as you stop pedalling when in normal operation, or
as soon as you have reached a speed of 25/45 km/h, the
eBike drive switches off the assistance. The drive is automat-
ically reactivated as soon you start pedalling again and the
speed is below 25/45 km/h.
The following options are available for switching off the
eBike system:
– Press and hold the on/off button (3) on the on-board
computer for at least 3 seconds.
– Switch off the eBike battery using its on/off button (bi-
cycle manufacturer-specific solutions are possible when
there is no access to the battery on/off button; see the bi-
cycle manufacturer operating instructions).
Note: This puts the Nyon (BUI350) into a standby mode.
– Remove the on-board computer from its holder.
If no power is drawn from the eBike drive for about
10 minutes (e.g. because the eBike is not moving) and no
button is pressed on the on-board computer or the operating
unit of the eBike, the eBike system, and therefore also the
battery, will switch off automatically to save energy.
Nyon (BUI350) goes into standby mode as a result.
Standby Mode
You can put your on-board computer into a standby mode,
which enables the on-board computer and system to start up
more quickly.
Standby mode can be activated as follows:
– To do this, press the on/off button (3) on the on-board
computer for at least 1 second, but no longer than
3 seconds.
– Wait 10 minutes until the system switches off.
– Switch the battery off using the on/off button on the bat-
tery.
Pressing the on/off button (3) on the on-board computer for
at least 1 second ends standby mode.
Standby mode ends and the on-board computer automatic-
ally switches off if the state of charge of the on-board com-
puter's battery is less than 75 %. In any case, the on-board
computer switches off at midnight (00:00) at the latest.
If Nyon (BUI350) cannot be switched on or does not work
properly, press and hold the on/off button (for approx.
15 seconds). This may correct the malfunction.

Power supply of the on-board computer

If the on-board computer is in the holder (4), a sufficiently
charged eBike battery is inserted into the eBike and the
eBike system is switched on, then the on-board computer
battery is powered and charged by the eBike battery.
If the on-board computer is removed from the holder (4),
the power is supplied by the on-board computer battery. If
the on-board computer battery's charge is running low, a
warning message appears on the display.
To charge the on-board computer battery, slide the on-board
computer back onto the holder (4). Note that if you do not
charge the eBike battery straight away, the eBike system will
automatically switch off after 10 minutes of inactivity. If this
happens, the on-board computer battery will also stop char-
ging.
