Electric bike how to detect problems with controller?

If you suspect that there is a problem with the controller of your electric bike, there are a few common signs to look out for. One of the most noticeable indications of a controller issue is a loss of power or a decrease in performance. This can occur if the controller is not properly communicating with the motor, or if there is a malfunction in the controller itself. Other signs to watch for include unusual noises, such as clicking or buzzing sounds, as well as warning lights or error codes that may appear on the bike's display. If you notice any of these symptoms, it is important to consult with a certified technician who can diagnose and repair the issue for you. Additionally, regular maintenance and tuning of your electric bike's system can help to prevent problems and prolong the life of your bike.
