How do a hub motor and a mid motor work, and what different between both of them?
A hub motor is the easieast way to achieve electric bikes, the output from it is transfered directly to the wheel, and becuase it doesn't interfered with a rider's interested, so that the electric bike provides a comfort way for riding experience.
Compareing with the hub motor, a mid motor requirs intelligented design to a bike frame to be compatible with the motor and simultaneously mantain it's engineered properties. The main difference between hub motor and mid motor is that mid motor transfers power through chain wheel, cassette and finally to the wheel, but hub motor transfers power directly to the wheel. It means that a rider would need to pay more attention to what gear ratio the cassette applied on, or the rider would find some frustration in riding the electric bike.
