- For
- E-bike owners diagnosing display and motor faults
- Worth noticing
- The reference covers 178 codes across ten named systems, including Bosch, Bafang, VanMoof, and Shimano STEPS.
Field notes
The reference divides its material by both manufacturer and display family, with separate entries for systems such as S866/S830, KT/Kunteng LCD, and Tongsheng TSDZ2. It also provides a parallel symptom route for owners who have no visible code, covering failures from charging and startup to pedal assist and throttle operation. The page explicitly separates basic checks from dealer-needed faults and warns that opening motors or batteries can void warranties.
