sIMPLEk Pro Tuning Tool for E-Bikes with Bosch Drives
General remarks and safety instructions
Warnings / Note on the Road Traffic Act
Installed in a compatible e-bike, the sIMPLEk Pro tuning module cancels the factory-integrated speed limit of the motor support. Therefore, the operation of the sIMPLEk Pro tuning module is prohibited and not permitted within the scope of the Road Traffic Act. Operation is only intended on private property and racetracks that are closed to public traffic. The use of an e-bike modified by tuning measures on public roads can lead to criminal liability for driving without a license (§ 21 StVG) and driving without insurance cover (§ 6 PflVG). Tuning measures on the e-bike can lead to the loss of warranty rights and manufacturer guarantees. Furthermore, tuning measures in the event of accidents can lead to a loss of insurance cover and of accident victim assistance services. The technical nature of the e-bike may not be designed for the use of tuning measures without further measures, which can lead to safety risks.
When installing in the e-bike, make sure not to damage any cables when installing the protective cover of the motor in order to avoid possible resulting short circuits or cable crushing, which can lead to electric shock or fire, among other things.
No liability is assumed for any present or future damage (direct or indirect) resulting from non observance of these operating instructions. Use at your own risk.
Please always wear suitable protective clothing and a helmet.
Installation
Remove the battery of your e-bike before you start the installation! The module is switched in front of the original sensor. To do this, the engine cowling usually has to be removed. Depending on the engine variant, additional tools are required for this.
Installation example Classic-Line (+)
Tools needed:
- Torx 20 8 mm
- ISIS Kurbelabzieher
- Optional:
- Werkzeug
Unscrew the 8 mm allen key (image 1). Remove the crank. If you can`t remove
the crank by hand, take a crank puller.
Remove the sprocket nut with the aid of the spider-tool (image 2).
Remove the 3 Torx screws with a socket (picture 3). Now the engine cover can
be removed. Pull the plug of the speed sensor, if necessary with a flat nose
pliers (picture 4).
Close the industrial plug of the SIMPLEk at the position of the previously
unplugged speed sensor. The supplied rubber tube has to be put off the plug of
the speed sensor until the sealing blades (image 8). Afterwards the speed
sensor and the male connector have to be connected (image 8). The polarity
does not need to be considered.
Installation example Bosch Active Line up to 2017 und Performance Line
(CX) up to 2019:
Tools needed:
- Torx 20 socket wrench
- 8 mm Allen key
- ISIS crank puller
- Optional: flat nose plier
Unscrew the 8 mm allen key (image 5). Remove the crank. If you can`t remove
the crank by hand, take a crank puller. Remove the 3 Torx screws with a socket
(image 6). Now the engine cover can be removed. If necessary, pull the plug
speed sensor with a flat nose pliers (image 7).
Now close the industrial plug of the sIMPLEk at the position of the previously
unplugged speed sensor. Now connect the plug of the sIMPLEk to the position of
the previously unplugged speed sensor. The speed sensor is then connected to
the connector of the sIMPLEk (image 8). The polarity does not need to be
considered.
Installation example Active Line (Plus) from 2018 onwards and
Performance-Line from 2020 onwards
Tools needed:
- Torx 20 socket wrench
- Optional: flat nose pliers
Remove the two torx screws with the socket wrench (image 9). Now the engine
cover can be removed. If necessary,
use flat-nosed pliers to pull out the speed sensor plug (image 10).
Now connect the plug of the sIMPLEk to the position of the previously unplugged speed sensor. The speed sensor is then connected to the connector of the sIMPLEk (image 8). The polarity does not need to be considered.
Installation example Bosch Performance- and Cargo-Line CX from 2022 and
newer
Tools needed:
- 4 mm Allen key (Fully cased version Torx 20 socket wrench)
- Optional: flat nose pliers
- ISIS crank puller (only for the full fairing version)
In the case of the fully clad version, the crank must also be removed. To do
this, loosen the 8 mm allen screw (image 3) and remove the crank using the
crank puller. Loosen the screws of the engine cover (image 11 or image 13).
Now the engine cover can be removed. If necessary, pull the plug of the speed
sensor (image 12 or image 14) using flat nosed pliers.
Now connect the plug of the simplek to the position of the previously unplugged speed sensor. The speed sensor is then connected to the connector of the simplek. When plugging in, make sure you hear/feel it clicks into place.
Operation
1:1-Mode
1:1 mode is always started after the e-bike has been operated in tuning mode or 1:1 mode for more than 15 seconds and switched off. In this mode, the e-bike behaves as if it were not modified.
Tuning mode
Activating the tuning mode:
- Switch on e-bike → [Display stays at 0.0 , 1:1 mode]
- Switch off the e-bike after it has started up completely, wait at least 5 seconds.
- Switch on e-bike → [Display shows 10.0 with correct calibration (otherwise a different constant value), tuning mode]
Speed representation: The speed actually driven remains readable in normal tuning mode with the speed limit not reduced and in stealth mode even with a reduced speed limit. Up to it is displayed 1 to 1, above it is displayed via the second digit and the decimal place. Speed display example: 23.5 → 35
Automatic route compensation: In order to compensate for the difference between the distance actually covered and the distance displayed, the maximum speed driven is displayed after about one minute of standstill until the distance has been covered. As soon as the difference has been compensated, the display drops to 0.0 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.
Note Bosch Gen4 engines with current firmware: We recommend running the automatic route compensation after each trip to counteract the “anti-tuning measures”.
Calibration mode
The calibration must be carried out once. It must be carried out at a standstill and with the battery pack inserted. It is called up automatically on the first start. If the e-bike does not have a speedometer, calibration is not required.
The calibration consists of two sections. First a rough calibration, then a fine one. In the first section of the calibration, an increasing speed is output on the speedometer. Switch off the e-bike as precisely as possible at 10.0 and wait at least 5 seconds. After switching on again, the fine calibration is carried out. A speed is output on the speedometer, which gradually approaches 10.0 in small steps and, in the meantime, briefly drops towards 0.0
As soon as 10.0 is displayed for the first time (it can take several minutes), switch off the e-bike again and wait at least 5 seconds.
Carrying out calibration at first start-up:
- Switch on the e-bike → [Display shows slowly increasing speed, calibration level 1]
- Switch off e-bike at approx. 10.0 , wait 5 seconds
- Switch on the e-bike → [Display shows slowly increasing speed and keeps dropping towards 0 , calibration level 2]
- Switch off e-bike at exactly 10.0 , wait 5 seconds
Start the calibration again manually:
- Switch on e-bike → [Display stays at 0.0 , 1:1 mode]
- Switch off the e-bike after it has booted up completely, wait 5 seconds
- Switch on e-bike → [Display shows 10.0 with correct calibration (otherwise a different constant value), tuning mode]
- Switch off the e-bike after 10.0 or another constant value is displayed, wait 5 seconds
- Switch on the e-bike → [CalibraQon level 1]
Cancel calibration: If the e-bike is ridden in calibration mode, the calibration is aborted and the sIMPLEk jumps back to 1:1 mode. In this case, no calibration took place.
E-bikes without a display: 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.
Setting the speed limit for motor support: The speed limit can be adjusted by calibrating at a speed other than 10.0 The table below shows the calibration values and the associated speed limits. It should be taken into account that the support starts to be throttled from the speed limit and ends approx. 6 later.
Environmental protection and disposal
