Description
Motor assistance above 25 km/h
The tuning module ensures that the motor support of your eBike is still active at speeds above 25 km/h.
Tuning can be activated and deactivated
You can use a clever on/off sequence for your eBike to optimize the tuning
- activate, deactivate or
- only once for the current ride. After switching off the eBike, the tuning is then off.
The activated tuning is signaled via the speedometer when the eBike is switched on. This means you always know which mode is active.
Real speed modified readable
To ensure that the motor assistance also works above 25 km/h, a lower speed than the actual speed is displayed when tuning is activated:
Below 22 km/h, the real speed is displayed.
Above 22 km/h, mentally move the decimal point displayed in the speedometer one place to the right. The leading 2 on the far left then no longer has any function.
Example: A speed of 32 km/h is displayed as: 23.2 km/h
Advantage: The verifiable average speed always remains inconspicuously below 25 km/h!
Maximum support speed adjustable
You can set the speed up to which the motor should provide assistance. This ranges from 31 to 50 km/h in steps of 1 km/h.
Once the cut-off speed has been reached, the motor assistance is gently reduced.
The speed remains visible even above the set switch-off speed.
Tip: We recommend that you do not ride faster than 35 km/h with the new Smart motors with assistance. This applies in particular from version 9.13.0 of the Bosch drive unit.
Supported Bosch motors
The brand new Bosch motors with the "smart system" will be supported from 2022 (BES3). You have a smart system if one of the following control units is installed:
Smartphone Grip 
System Controller 
Purion 200 
Mini Remote 
LED Remote 
Kiox 300 / 500 
Intuvia 100
If one or more of the above control units or displays are installed, then this tuning module is compatible with them. There are only 2 exceptions. The tuning does not work if the eBike:
- has an ABS installed
- has a valve solenoid (RIM solenoid). This is a small sleeve above the valve of the rear tire.
In both cases, the slot for the speed sensor is not occupied and has a dummy plug. In this case, the magnet on the spokes or on the brake disk is also missing. Please check this before purchasing.
If you have a different display to the one shown above, then the bike is most likely not a Bosch Smart System. In this case, please select this solution: E-bike tuning for Bosch motors (Gen 1 - 4)
