Wheel-hub motor is placed at the center of the automobile’s wheel. It transfers the motor’s power directly to the wheel to propel the vehicle.

Mid-drive motor uses the vehicle’s chain drive to transfer the motor’s power to the rear wheel. It stops the vehicle completely if the chain breaks or jams.

Wheel-hub motor produces less mechanical stress on the vehicle as compared to their belt counterparts.

A mid-drive motor puts a lot of force on the chain and cogs, requiring more attention to mechanical wear and tear.

As an independent drive system, the wheel-hub motor keeps all its components inside a motor casing. Hence it require little or no maintenance.

Because of the increased number of moving parts in a mid-drive motor, its overall maintenance cost increases.
