Setting The Assistance Level - Bosch Purion BUI215 Original Operating Instructions

– The wheels of the eBike are locked (e.g. by applying the
brakes or hitting an obstacle);
– The speed exceeds 6 km/h.
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.

Setting the assistance level

You can set the level at which the eBike drive assists you
while pedalling on the on-board computer. The assistance
level can be changed at any time, even while cycling.
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

quired assistance level appears on the indicator (i). To de-
crease the assistance level briefly
If the display is set to TRIP, TOTAL or RANGE, the selected
assistance level will only be superimposed briefly (for ap-
prox. one second) on the display when switching over.
Switching bicycle lights on/off
On the model in which the bike lights are powered by the
eBike system, pressing the button + for a medium length
of time will switch on the front and rear lights simultan-
eously. Pressing the button + for a medium length of time
will switch the lights off again.
The lighting symbol (h) is displayed when the light is on.
Check that your bike lights are working correctly before
every use.

this saved status accordingly after a restart.
Switching the bike lights on and off has no effect on the
backlighting of the display.
