Mid-drive and rear-drive motors each have their own pros and cons for mountain bike modifications.
To repair the wheel hub motor, you need to first diagnose the fault type, and then conduct troubleshooting and repair according to the fault type. However, if the wheel hub is seriously damaged, it will need to be replaced with a new one.
Modern hub motor technology has advanced significantly, incorporating many of the same sensors and controls as mid-drive systems. Both can effectively power high-end e-bikes depending on the overall design.
The selection of an electric motor involves evaluating multiple technical considerations to ensure the best match for an application's specific requirements.
