high quality 4" 4inch waterproof hub motor wheel

A hub motor is an electric motor that turns a wheel without the use of a transmission. This is accomplished because a hub motor is built directly into the wheel's hub, which is the point around which the wheel rotates. This bypasses the need for a transmission, so hub motors are more efficient, especially at high rates of speed. It is common to find a hub motor on an electric bicycle.

Hub motors, as an idea, have been around since the late 19th century. They originally were conceived for use in automobiles, but modern hub motors are used almost exclusively on electric bicycles. Motorized bicycles are more common in Asia than in other parts of the world, but they have continued to grow in popularity elsewhere because of technological advances. Some motorized bicycles are manufactured, but it can sometimes be cheaper for a hub motor to be installed on a bike as an aftermarket add-on. There are many conversion kits available, including kits for modifying a Chinese hub motor to fit a bicycle of American dimensions.
