Battery Charge Indicator - Bosch Intuvia BUI255 Ergänzung Zur Originalbetriebsanleitung

Switching on/shutting down the on-board
computer
To switch on the on-board computer, briefly press the on/
off button (5). The on-board computer can also be switched
on when it is not inserted in the holder (if the internal battery
is sufficiently charged).
To switch off the on-board computer, press the on/off but-
ton (5).
If the on-board computer is not inserted in the holder, it
automatically switches off after 1 minute to save energy if no
button is pressed.
If you are not going to be using your eBike for several
u
weeks, remove the on-board computer from its
holder. Store the on-board computer in a dry environ-
ment at room temperature. Regularly recharge the on-
board computer's battery (at least every 3 months).

Battery charge indicator

The battery charge indicator (i) displays the state of charge
of the eBike battery, not that of the on-board computer's in-
ternal battery. The state of charge of the eBike battery can
also be checked on the LEDs of the battery itself.
Each bar of the battery symbol on the indicator (i) repres-
ents approximately 20 % of the capacity:
The eBike battery pack is fully charged.
The eBike battery pack should be recharged.
The LEDs of the battery charge indicator on the
battery go out. The capacity for assisting the
drive has been used up, and assistance is
gently switched off. The remaining capacity is
made available for the lighting and the on-
board computer. The indicator flashes. The ca-
pacity of the eBike battery is enough for about
two hours of lighting. This does not account for
other consumers (e.g. automatic gearbox, char-
ging external devices at the USB port).
If the on-board computer is removed from the holder (4),
the last displayed state of charge of the battery is saved. If
an eBike is powered by two batteries, the battery charge in-
dicator (i) displays the state of charge of both batteries.
OFF
If an eBike has two batteries inserted into
it and both batteries are charged on the
MPH
KM/H
bike, the charging progress of both bat-
teries will be indicated on the display
(the left-hand battery pack is being
charged in the illustration). You can also
tell by the flashing indicator on the bat-
tery which of the two batteries is being
charged.
Setting the assistance level
On the operating unit (9), you can set the level of assistance
you want the eBike drive to provide you with while pedalling.
The assistance level can be changed at any time, even while
cycling.
Bosch eBike Systems
Note: In some models, the assistance level may be preset
and cannot be changed. There may also be fewer assistance
levels available than stated here.
The following assistance levels are available as a maximum:
– OFF: Motor assistance is switched off. The eBike can only
be moved by pedalling, as with a normal bicycle. The walk
assistance cannot be activated at this assistance level.
– ECO: Effective assistance with maximum efficiency, for
maximum range
– TOUR/TOUR+:
TOUR: Steady assistance, long range for touring
TOUR+: Dynamic assistance for natural, sporty cycling
(only in conjunction with eMTB)
– SPORT/eMTB:
SPORT: Powerful assistance, for mountain biking and
cycling in urban traffic
eMTB: Optimum assistance whatever the terrain, rapid
acceleration when starting from a standstill, improved dy-
namics and top performance (eMTB only available in
combination with the drive units BDU250P CX, BDU365,
BDU450 CX and BDU480 CX. A software update may be
required.)
– TURBO: Maximum assistance even at a high cadence, for
sporty cycling
To increase the assistance level, press the + button (12) on
the operating unit repeatedly until the required assistance
level appears on indicator (b). To decrease the assistance
level, press the – button (11).
The requested motor output is displayed in the indicator (a).
The maximum motor output depends on the selected assist-
ance level.
When the on-board computer is removed from the holder
(4), the assistance level that was last displayed is saved; the
motor output indicator (a) remains empty.
Interaction between the eBike system and gear-
shifting
The gear shifting should be used with an eBike drive in the
same way as with a normal bicycle (observe the operating in-
structions of your eBike on this point).
Irrespective of the type of gear shifting, it is advisable that
you briefly reduce the pressure on the pedals when changing
gear. This will aid gear shifting and reduce wear on the
powertrain.
By selecting the correct gear, you can increase your speed
and range while applying the same amount of force.
For this reason, follow the gear change recommendations
provided by the indicators (g) and (h) on your display. If in-
dicator (g) is displayed, you should change to a higher gear
with lower cadence. If indicator (h) is displayed, you should
select a lower gear with higher cadence.
Switching bike lights on/off
On the model on which the lighting is 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 using the bike
light button (2).
