Tips: Hub motor vs. Central motor

Central motor		Hub motor
Advantages	Disadvantages	Advantages	Disadvantages
Central motor has better torque and better climbing performance.	Relatively more expensive	Hub motors are cheaper than central motors.	Excessive unsprung weight, uneven weight distribution (especially the front wheel hub).
Central motor has better overall performance.	The drivetrain is more prone to wear.	There are more options for gear in wheel motors, suitable for customization.	The front drive requires a larger torque arm and a more powerful in wheel motor.
Central motor has low center of gravity distribution.	Lack of a complete transformation plan, currently central motor is mainly applied to a complete set of electric bicycles.	The wheel hub motor can be driven forward and backward, using AWD (all wheel driver) system.	The climbing ability of the hub motor is relatively weak.
Central motor provides higher top speed through gears.	Central motor uses more electricity.	The strain on the wheel hub motor drive system is small.	Hub motors consume more power at higher speeds.
