These days more and more hub motors are used for ebikes.We also call them electric bike motors.For e bike motor,it’s an important key product.It seems bike engine.

We know gasoline engine.The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine, the expansion of the high-temperature and high -pressure gases produced by combustion apply direct force to some component of the engine. This force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy.

Gasoline engine will let co2, so2 pollute environment and be bad for health.

For electric bike motor,it uses battery,one kind of clean energy.
Hub motor is make up of rotor winding,magnet,hub,axis,bearing,hall sensor…

Hub motor electromagnetic fields are supplied to the stationary windings of the motor. The outer part of the motor follows, or tries to follow, those fields, turning the attached wheel.

About motor speed,power..we can customize it according as customers’ actual need by change gauge of the coil wires and/or the turns number of the coils and/or the height of magnet

There are some parts of hub motor.
