The first sub-category of hub motors is divided by their placement – either in the front or rear wheel hub. There are a few e-bikes out there that use dual (both front and rear) hub motors, but these tend to be special cases. The vast majority of e-bikes with hub motors have them mounted on the rear wheel. These types are known to give their riders the feeling of being pushed from behind, though this characteristic is often subtle and easy to get used to.
The power needed to run a hub motor depends on various factors such as the motor's size, type, and intended use. Generally, hub motors require a power supply ranging from 250 watts to 1000 watts or more for electric bicycles and other vehicles.
The weather can affect the performance of a hub motor due to changes in temperature and moisture levels. These environmental factors can impact the motor's efficiency and potentially damage its components over time.
Geared hub motors have an internal gear reduction mechanism, while gearless hub motors do not. Gearless hub motors are generally larger, heavier, and more powerful, while geared hub motors are smaller, lighter, and more efficient.
