A hub motor is an electric motor that is integrated into the wheel hub of a vehicle, such as an electric bicycle or scooter. This design allows the motor to directly drive the wheel, providing efficient power transfer and reducing the need for complex mechanical components like chains or gears. Hub motors are popular for their simplicity and ease of installation. There are two main types of hub motors: geared and gearless. Geared hub motors use internal gears to increase torque, making them suitable for hilly terrains, while gearless hub motors offer a smoother ride and are often quieter. Both types contribute to the growing popularity of electric vehicles, including those powered by batteries from companies like Tesla.
