Dongles

Here you will find tuning dongles for e-bikes — small modules that you connect to the motor or controller to adjust the speed limit. The selection focuses on common e-bike motors such as the Bosch BES2 and Brose, with dongles from Polini, among others.

Check which motor brand and generation is in your e-bike; dongles are motor-specific and not interchangeable. Please note that using a tuning dongle may affect the type approval of your e-bike.
