What is the B100R?
The B100R is an control unit with integrated LCD display on
the handlebar. Since all important information is displayed on
the high-contrast 1.4-inch monochrome LCD, a larger display
in the centre of the handlebar is not required - the B100R is a
stand-alone system.
Mounting the B100R
Figure 1: B100R mounted on handlebar
The B100R is mounted on the left side of the handlebar of
your pedelec [Figure 1]. The entire surface of the LCD display
serves as a rocker switch for the "+" and "-" settings.
Additionally, the control unit has three buttons; two on the
side and one on the top. The switch and buttons allow you to
change the settings on your pedelec, e. g. the degree of
motor assistance, at any time without taking your hands off
the handlebars.
When mounting the B100R, observe the following [Figure 2]:
Figure 2: Correct torque, avoid pressure on the housing
Torque: The B100R is fixed with a 2.5 mm hexagon socket
head screw. Please do not tighten the screw with more than
1 N m (Newtonmeter) torque.
Caution: Make sure that nothing on the handlebar such as the
handle or brake lever presses against the side or underside of
the B100R (yellow arrow). This could affect the function of the
rocker switch.
Figure 3: Best viewing angle
The display is designed with an optimum viewing angle of
25 degrees below the vertical [Figure 3]. Loosen the fastening
screw and tilt the display on the handlebar until you have
found the optimum angle for your riding position. Then
retighten the screw with a torque of not more than 1 N m.
Notes on the connection of
the B100R connector
Figure 4: Female connector and male connector
If you need to open both ends of the plug on the cable
leading from the B100R to the pedelec frame, follow the
instructions below when reconnecting the plug.
The male connector on the cable comes from the B100R
[Figure 4, right], the female connector is at the other end of
the cable [Figure 4, left].
Figure 5: Align connector markings
Caution: The ends must be correctly aligned when connecting.
Coupling and plug are provided with a mark - align the
markings correctly [Figure 5].

Figure 6: Carefully press the plug together
Caution: Carefully press both ends of the connector together
[Figure 6]. If the two ends are not aligned correctly, the plug
may be damaged.
When disconnecting or connecting, be careful to grip only the
ends of the connector, not the cable itself. When plugging the
connector together, do not bend the cable to avoid kinks and
damage.
Overview of the Rocker
Switch and the Keys
Figure 7: Rocker switches and keys
The entire display of the B100R is a rocker switch. The display
can be pressed at the top for the "+" function and at the
bottom for the "-" function. In addition, there are three
buttons for "On/Off", "Light" and "Set" [Figure 7]. The rocker
switch and the keys have the following functions:

explanation
Switching on the system
The complete system consists of the B100R and the pedelec.
To turn on the system, press either the "On/Off" button on the
B100R or the button on the battery (varies depending on the
model). The display will turn on after a few seconds.
Figure 8 shows all segments of the display. While riding, the
display does not show all segments at once - it looks more
like the screen above [Figure 7]. In the above example, at a
speed of 27 km/h, you are riding with the third support level.
The battery is not fully charged, but it is well charged, and you
have covered a distance of 65.3 kilometers on this trip.
Switching off the system
To turn off the system, press either the On/Off button on the
B100R or the button on the pedelec battery (depending on
the model). The display and your pedelec will turn off.
Auto turn off
If your pedelec is not used for several minutes, the system
switches off automatically. By pressing the "On/Off" button,
the system is switched on again.

V0.2 | 11.11.2019 14:46 7/8
1. distance travelled or range (chapter 6.5)
2. trip distance (TRP), range (R) or odometer (T)
(chapter 6.5)
3. assist level (chapter 6.7)
4. speed (chapter 6.8)
5. mph = units in miles per hour (chapter 6.6)
6. km/h = units in kilometers/hour (chapter 6.6)
7. state of charge of battery (chapter 6.9)
Note: While riding, the display does not show all segments at
the same time.
Warning: Do not let the display
distract you so much that you lose
attention to your surroundings. In
the worst case, such distractions
can result in serious injury or
death..
Lighting
Press the "Light" button (Chapter 5) to switch on the lighting.
Normally the lighting on the pedelec consists of a headlight
and a rear light. Although there is no visual representation of
the lighting on the LCD display, the B100R's backlight turns on
and remains on as long as the lighting is on. Press the light
button again to turn off the backlight.
Pushing aid
Press and hold "+" on the rocker switch (chapter 5) to switch
on the pushing aid. The pushing aid switches on the motor to
move the pedelec forward slowly (6 km/h) without the driver
having to pedal. This function can be useful, for example, if
you push the pedelec up a ramp. There is no visual indication
of the pushing aid on the LCD display; the function is stopped
as soon as "+" is released. If you pedal or drive faster than 6
km/h, the pushing aid will end.
Distance travelled, range and odometer
At the top right [Figure 8, number 2], the display shows either
the travelled trip distance (TRP), the estimated remaining
range of the pedelec (R) or the odometer (the total distance
travelled by the pedelec = T). The default setting for the
display is TRP. Press and hold the "-" key (chapter 5) to reset
the TRP counter to 0.
To change the display settings, press the "Set" button once
(chapter 5) to display range (R) or twice to display odometer
(T). Press the "Set" button again to advance the display in the
order TRP / R / T; after T the display returns to TRP.
The display will count up to 9999 kilometers or 6213 miles. If
the odometer reaches more than that, it restarts with 0.
Units
Long-push „Set“ (chapter 5), to toggle between metric units
(km/h = kilometers/hour) and Imperial units (mph = miles per
hour). The units are shown in Figure 8 (numbers 5 and 6).
Choice of assist level
You can always press "+" and "-" on the rocker switch
(chapter 4) of the B100R to change the degree of motor
assistance. This allows you to make optimum progress with
your pedelec in any situation and on any terrain. There are
four assist levels and "Off" (level 0), so a total of five levels.
The symbols for the levels are shown in Figure 9.
Figure 9: Assist levels
Level 4: highest assist level with the most power, drains
battery fastest
Level 3: second highest assist level
Level 2: second lowest assist level
Level 1: lowest assist level, battery lasts the longest
Level 0 (Off): no assistance, pedelec is like a bicycle
The motor assists only as long as you
pedal. If you do not pedal, the motor
interrupts the assistance.
Speed
The largest part of the display shows the pedelec’s current
speed [Figure 8, number 4]. To change the units (km/h or
mph), press and hold the "Set" button.
Battery state of charge (SoC)
The battery symbol at the bottom of the display indicates the
battery’s state of charge in five segments [Figure 10]. Please
note that each segment only indicates a range of 20 %, not an
absolute value. For example, if three segments are displayed,
the battery is approximately half full, but not necessarily
exactly 60 % full - the charge level is in the range of 41 % to
60 %. When the battery charge drops to 10 % or less, the last
of the five segments starts flashing to indicate the low state of
charge.
