FAQ
(further Help you can nd at support.maintronic.de)
I have done the installaon exactly like shown, but the
switchoverpoint is not percepble?
ANSWER:
Distance and Posion of the magnet aecng the
switching me of the speed sensor. The shorter the
switching me, the sooner is the switchoverpoint and
conversely. Try to turn up the pedal by hand while the
engine is turned o ll 50km/h and watch the speedo-
meter.
If the switchoverpoint is below 12km/h or over 28km/h
or not at all please contact your specialist dealer or the
Sx2 Support >>> sx2@maintronic.com
How can I inuence the switchoverpoint?
ANSWER:
If the speed sensor with the magnet is moved into the
axis direcon, the switching speed increase.
Conversely the speed sensor with the magnet is moved
outside to the re direcon, the switching me is shor-
ter and the switching speed is lower.

The best soluon is to connect the cablekit directly be-
hind the speedsensor plug inside of the engine termi-
nal.
It is located behind the stone chip cover of the engi-
ne which is screwed on with 3 Torx screws. At rst the
crank crank has to be removed. For this reason the fol-
lowing special tools are required: 8mm 5-hex key to un-
lock the crank screw, Isis crank puller for dismounng
the crank. And a Torx T20 key for the chip cover screws.
Once the crank and the protecve cover are removed
you get access to the speedsensor plug(1). The next
step is to unplug the speed sensor plug (1) from the en-
gine carefully.
Connect the Sx2 Tuning-Dongle parallel to the speed-
sensor. Please take care of the polarity. Red to red (3)
and black to black (4). The orange wire (5) is connected

For connecng the wires with the blade connectors
insert each wire (without stripping) of the Sx2 Tuning-
Dongle cable into the one-sided openings of the blade
connectors (2).
The related wires of the speedsensor and the + wire
of the control unit Intuvia (6) are inserted into the
through-opening of the blade connectors. Now press
down with your hand the blade connectors (2) rmly.
Compress with a pliers as possible parallel.
Once the terminals are crimped, the speedsensor plug
(1) should be reconnected to the engine and the chain
applied to the chain wheel.
Now the pedal has to be turned up slowly by hand and
the speedometer should be checked for funcon. If the
speed is shown on the display repeat the procedure
with a plugged Sx2 Tuning-Dongle into stereo jack so-
cket (5). Unl the switch point is reached, the shown
speed jumps to the half speed.
Aer that, assemble the hood and the e-bike together.
The cablekit should be mounted in a way to protect
the connectors from splashing water and mechanical
damage.

connected cablekit.
FAQ
(further Help you can nd at support.maintronic.de)
I have done the installaon exactly like shown, but the
switchoverpoint is not percepble?
ANSWER:
Distance and Posion of the magnet aecng the
switching me of the speed sensor. The shorter the
switching me, the sooner is the switchoverpoint and
conversely. Try to turn up the pedal by hand while the
engine is turned o ll 50km/h and watch the speedo-
meter.
If the switchoverpoint is below 12km/h or over 28km/h
or not at all please contact your specialist dealer or the
Sx2 Support >>> sx2@maintronic.com
How can I inuence the switchoverpoint?
ANSWER:
If the speed sensor with the magnet is moved into the
axis direcon, the switching speed increase.
Conversely the speed sensor with the magnet is moved
outside to the re direcon, the switching me is shor-
ter and the switching speed is lower.

Fehleranalyse
If the cablekit is connected but the dongle has no operaon,
it´s possible the cablekit does not have the right connecon or
the voltage is not enough.
To make sure the connecon is ok, the present voltage and cur-
rent can be checked with a measurement device.
Please note !!! The magnet of the speedsensor may not ex-
ceed over the Sensor during the measurement.
Voltage measurement:
Therefor is the best way to take a 3.5mm stereo jack with two
male connectors and measure according to the below connec-
on diagram.
Between the p and the front ring has to be +5VDC. The p of
the jack is Ground.

Current measurement:
A current between 5mA and 10mA are necessary. The currrent
is measured also between p and front ring. The p of the
3.5mm jack is ground.
Important: The measument device has to set on the funcon
current and the + measurement line plugged into the provided

If your eBike with Bosch engine has already light ins-
talled and the light funcon on the control computer
is enabled, one of the two exisng light cables need to
be connected to our Sx2KB-Plus power switch cablekit.
To use the opon, the Sx2 Tuning-Dongle with the light
switch on and o.
For this purpose, the insulaon need to be removed
about 10-15 cm behind the plug from one of the two
light cables.
Please take care not to damage the single wired.
The insulaon of the two wires has to be removed ap-
prox. 1 cm.
Connect the twisted wires to the terminals on the termi-
nal block (terminal designaon 1).
Please observe polarity:
red = posive pole; black = minus;
Either the front or rear light can be connected. It is only
important to connect the light cable to the input with
the (1) (to the right of the speed sensor connecon (S).
To connect cables to the terminal block, use a screwdri-
ver to push the white lever, as shown in the picture
below, to the le in the direcon of the opening and
insert a stripped cable into the opening. Then push the
lever to the right again. Check cable for ghtness.
Both wires (+ red and - black) must be connected. If the
cable for the light is connected to the terminal block
(terminal designaon 1), the speed sensor with the in-
sulaon displacement terminal can be connected accor-
ding to the operang instrucons.
Finally, put the plug back into the engine compartment.
Kink the cables and
twist the wires.
