is tuning authorized?
No, tuning is prohibited. If you nevertheless use a tuning kit or manipulate your Bosch eBike system in any other way, you lose your guarantee and warranty claims on the purchased bicycle. Through improper handling of the system in general, you reduce the service life and risk damage to the Drive Unit and the bicycle. In addition, you endanger your safety and that of other road users, thus risking high personal liability costs and even the possibility of criminal prosecution in case of accidents which are due to tuning. For this reason, Bosch eBike Systems instructs all eBike riders and providers to refrain from tuning.
