E-bikes: inner rotor vs outer rotor - what is the difference?

E-bike motors split clearly by inner-rotor and outer-rotor designs, with differences in noise, efficiency, cost and applications, according to a comparison by Chinese drive-system maker Bafang cited by BikeBiz. Bafang said inner-rotor motors tend to be quieter and smoother, while outer-rotor motors offer simpler structures and cost advantages. It said each design should be chosen based on purpose and overall product design, stressing integration with controllers, batteries and other components.
