Electric bicycles are becoming increasingly popular forms of two-wheeled electric transportation for both commuting and pleasure riding. The two most common electric motor styles used in today’s electric bicycles are hub motors and mid-drive motors. Which one is best for your needs? Read on to learn more and find out!
Hub motors, which place the electric motor in the center of a bicycle wheel, are certainly the most common form of electric bicycle motors.
Mid-drive motors, which house the motor closer to the center of the bicycle and transfer the motor’s power to the rear wheel via the bicycle’s chain drive, have become much more common over the last 2-3 years, and are cutting significantly into the hub motor’s lead as the king of the e-bike motors.
Both have a number of unique advantages and disadvantages, so choosing the right motor for you will largely depend on your requirements and which advantages seem more useful to your needs.
Bike Torque Compare:
When you get a bike with same torque(100NM) hub motor&Mid drive motor, the bike with Mid drive motor will have more torque, Why?
Hub motor: When you use the bike with pedal assist or Throttle only, the bike rear wheel get direct torque from the hub motor, so the bike torque=100NM.
Mid motor: When you use the bike with pedal assist or Throttle only, the bike get the power from Mid motor chain wheel to rear sprocket, so when your bike have a front 40T chain wheel&rear 10T sprocket, The bike torque is 40/10*100NM=400NM.
