Which parts of the Bosch drive system can riders repair themselves?

If an eBike fitted with a Bosch drive system develops a defect related to our eBike drive, we recommend consulting a professional bicycle retailer specializing in eBikes. The retailer will have all the right special tools such as a software diagnosis tool to identify the exact problem. Even ambitious bicycle repair enthusiasts may not be able to repair the defect and there is a significant risk that unprofessional repairs will compromise the safety of the overall system.
