1. General remarks and safety instructions
The establishment of the completed assembly set or the sIMPLEk Pro, within the scope of the St O, is forbidden
and not accepted. The use is only provided for closed-off public traffics as well as for private grounds and race
courses. No liability is accepted for current or future damage caused by commissioning of the assembly set. Use
at your own risk.
The sIMPLEk-Stick is compatible with the following E-Bike engines:
•Bosch (Classic-, Active (Plus)- und Performance-Line (CX))
•Yamaha (PW, PW-SE, PW-X, GIANT SyncDrive)
•Impulse (2.0, E O-RS)
•Brose
•Shimano
The sIMPLEk Pro Tuningmodule, obstructed in a compatible E-Bike, causes the suspension of the factory-integrated
speed regarding the support of the motor. Thus, the establishment of the completed assembly set, within the scope
of the St O, is forbidden and not accepted. The use of the sIMPLEk Pro Tuningmodule is only provided for closed-
off public traffics as well as for private grounds and race courses.
Please note that the technical characteristics of your e-bike may not be designed for the use of tuning measures
without further technical adjustments. The use leads to the warranty loss of the e-bike. If the e-bike concerned has
an operating license, it will be extinguished.
Regarding the installation of the E-Bike, please make sure not to damage any cables while installing the protection
cover of the motor. Thus, you can prevent electrical shorts which could lead to major cable bruises or fires.
Liabilities for any damages will not be assumed (directly or indirectly) that may arise by activating the completed
assembly set. Use at your own risk!
Please put on a suitable helmet at all times!
2. Installation
Before you start with the installation, remove the battery of your E-bikes!
The sIMPLEk is upstreamed in front of the original sensor. For this purpose the motor cover has to be removed.
Depending on the engine version you need additional tools.

2.5. Installation based on an engine version Impulse
The necessary disassembly work to get to the connector of the speed sensor and for the plug coupling or insulation
displacement terminal vary depending on the e-bike manufacturer.
In the case of head-side integration of the motor into the frame, access to the cable harness is often achievable
without disassembly work. If this is not the case, the motor must be removed to install the sIMPLEk.
The sIMPLEk Pro plugs should be inserted between the plug connections in picture 23. This is the plug connection of
the speed sensor (2-pin assigned, motor side light red, gray and sensor side black and red) and a 4-pin connector (4-
pin on both sides: white, yellow, brown, light green).
Using a screwdriver, disconnect the two plug connections from picture 24 and now connect the sIMPLEk plugs to
the previously disconnected plugs (picture 25). Make sure the plug connections are correctly seated (audible click
sound when snapping into place).

3. Handling
The sIMPLEk includes 3 operation modes: [1] 1:1-Modus
[2] Tuningmode
[3] Calibrationmode
A change from one operating mode to another is achieved if in each mode the e-bike is switched off immediately
after the start and then waited at least 5 seconds and then restarted.
Attention! E-bikes without a display or speedometer: In this case, no calibration is necessary. When using the
module for the first time, you must inform the module that there is no display by driving off immediately or spinning
the rear wheel.
Attention! BRO E engines: When changing the operating mode, it is necessary to switch the e-bike to deep
sleep mode when it is switched off. This is achieved by holding down the power button on the control unit or on the
battery for at least 3 seconds. With some firmware versions, switching off to deep sleep mode can only be achieved
by briefly removing the battery. This also applies to the switch-off processes during calibration.
Attention! Bosch Gen4 engines: We strongly recommend running the automatic route compensation
after each trip to counteract the "anti-tuning measures".

3.1. 1:1-Mode
After the E-Bike will be running longer than 15 second in the tuning-mode or 1:1-mode and switched off, the Ebike
will always start in 1: 1 mode. During this mode the E-Bike behaves as if it was not modified.
3.2. Tuningmode
In order to start the tuning mode, the e-bike has to be switched off immediately after starting in 1: 1 mode (Brose:
press and hold the power button for at least 3 seconds or remove the battery briefly), wait at least 5 seconds and
then switch it on again. So proceed as follows:
1. Switch on E-Bike → [display shows 0,0


, 1:1 Mode]
2. Switch off the e-bike after it has started up completely (BROSE DeepStandby!), wait 5 seconds.
3. Switch on E-Bike → [display shows 10,0


if calibration is correct, tuningmode]
10,0


is displayed on the speedometer to signal that the tuning mode is activated. The actually travelled speed
remains readable during the tuning-mode. Up to 20


, it is issued 1 to 1. Above 20


(mph) the speed will be
displayed over the second number and decimal place. If the speedometer does not have a decimal place, the
displayed speed is accordingly less accurate. Examples:
22.7


→ 27


23.5


→ 35


24.8


→ 48


Automatic route compensation
In order to compensate for the difference between the distance actually driven and the distance displayed, the
maximum speed driven is displayed on the speedometer after about a minute of standing still until the distance has
been covered. As soon as the difference has been compensated, the speedometer drops back to 0.0 km/h and the
e-bike switches itself off after a while. If the e-bike is switched off beforehand, the sIMPLEk saves the difference and
catches up later. As a result, the maximum speed and the distance traveled/total distance are correctly displayed.
Reset maximum driven speed
The maximum driven speed, which is displayed to compensate for the difference in the distance covered, is reset by
restarting the calibration and either carrying it out completely or aborting it by driving off. If the calibration is aborted
by starting up, sIMPLEk jumps into 1:1 mode. The maximum speed is now reset.

3.3. Calibrationmode
The calibration has to be carried out once and has to be shifted during standstill and with an inserted rechargeable
battery pack. On first start, the calibration will be automatically called up. It consists of two sections. At first it will
be grossly calibrated, then more precise.
In the first section of the calibration, an increased speed will be displayed on the speedometer. Switch off the E-Bike
as closely as possible at 10.0


(Brose: press and hold the power button for at least 3 seconds or remove the battery
briefly), wait at least 5 seconds and then switch it on again. If you switch on again, precised calibration will be start.
You can see the speed on the speedometer which comes closer in small steps to 10.0


and can fall in the meantime
repeatedly to 0.0


. As soon as the 10.0


will be displayed for the first time, again switch off the E-Bike (Brose:
press and hold the power button for at least 3 seconds or remove the battery briefly). Thus, the calibration is
completed. In short:
1. Switch on the e-bike → [Display shows slowly increasing speed, calibration stage 1]
2. Switch off the e-bike at approx. 10.0 km/h (BROSE: DeepStandby!), wait 5 seconds
3. Switch on the e-bike → [Display shows slowly increasing speed and keeps dropping towards 0 km/h,
calibration stage 2]
4. Switch off the e-bike at exactly 10.0 km/h (BROSE: DeepStandby!), wait 5 seconds
Cancel calibration: If you move the E-Bike during the calibration mode, the calibration will interrupt and the sIMPLEk
will goes back into the 1:1-mode. In this case a calibration does not take place.
Carry out calibration again: To start the calibration mode manually, the e-bike must be switched off immediately
after starting in the tuning mode (Brose: press and hold the power button for at least 3 seconds), wait at least 5
seconds and then switch on again. So proceed as follows:
1. Switch on the e-bike → [display shows 0.0 km/h, 1:1 mode]
2. Switch off the e-bike after it has started up completely (BROSE: DeepStandby!), wait 5 seconds
3. Switch on the e-bike → [display shows 10.0 km/h with correct calibration (otherwise a different
constant value), tuningmode]
4. Switch off the e-bike immediately (BROSE: DeepStandby!), wait 5 seconds
5. Switch on the e-bike → [Calibration stage 1]
etting the speed limit for motor support: The speed limit can be adjusted by calibrating at a speed other than 10.0
km/h. The table below shows the calibration values and the associated speed limits. It should be noted that the
reduction in support begins when the speed limit is reached and ends approx. 6 km/h later.
