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. Installation and operating video under the following link: https://www.youtube.com/watch?v=MXWPQhByYSc&t=388s&ab_channel=VOLspeedEbikeTuning
Please check for compatibility before purchasing. Compatible with e-bikes that use the Bosch Smart System, you can see this by means of the displays installed by the Bosch Smart System: Kiox 300 / Kiox 500 / Intuvia 100 / Purion 200 / Purion 400 as well as the control units: System Controller, Mini-Remote, LED Remote. See picture 2 (selection guide) not compatible with other Bosch engines or Bosch smart systems with rim magnet or ABS system. The right module for Bosch engines in front of the smart system under the following link: https://www.amazon.de/dp/B09MJFJ2L6?ref=myi_title_dp
Note: When tuning is activated, a speed is displayed from 21 km/h and a distance that is too small is measured. The mileage is therefore too low after using the tuning.
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.
Additional functions: activatable dynamic mode, leads to significantly smoother control at the speed limit. Individual activation code adjustable. The tuning is switched on and off, as well as the freely selectable speed limit between 25 km/h and 45 km/h, is done via the buttons on the control panel.
