How does the Hub motor versus mid drive work when not using the boost?

A: The mid drive motor (crank motor) is providing a boost to the crank torque, the power is transmitted by the chain to the rear freewheel. The bike transmission gear ratio affects the torque and speed. Also the freewheel sprocket lets the wheel freely roll with no drag.
The geared hub motor has a clutch inside which engages the motor when motorized and free wheels when motor is not providing a torque. The brushless geared hub motor does not have any drag when riding as a normal bike; it feels just like 2 free ball bearing.
