Main highlights

Unique use of original rim magnets. No additional speed sensor required. Very high-quality tuning module made in Germany. You can freely configure the speed limit between 25 km/h and 45 km/h. The installation is simple and is done via plug and play by plugging into the motor. No smartphone or PC is required, the module works immediately after installation on the motor thanks to the automatic initialisation.
Note: when tuning is activated, from approx. 21 km/h is too low and a distance is too low. This is necessary to permanently avoid tuning detection.
Compatible with software version 16.19.0 and all software versions before it. Please do not perform any further software updates of the e-bike afterwards, as this may lead to incompatibilities. Once installed updates can no longer be undone, even by the dealer.
Compatible with e-bikes equipped with a Bosch Performance Line CX motor (BDU37 & BDU38) and a rim magnet. Important: this tuning only works on e-bikes with rim magnet. Models without rim magnet are not supported. E-bikes with ABS system are also not supported. The matching module for Bosch engines in front of the Smart System can be found under the following link: https://www.amazon.de/dp/B09MJFJ2L6?ref=myi_title_dp
Additional functions: activatable dynamic mode, leads to significantly smoother control at the speed limit. Switching the tuning on and off, as well as the infinitely freely selectable speed limit between 25 km/h and 45 km/h, is carried out via the support levels on the display/control panel.
