The Hub-drive motor is built directly into the hub of the wheel. It is usually placed on the rear wheel of electric bikes. The hub motor and the stator are connected through a gear reduction system. Motors like to turn at a fast speed, much faster than your bike wheels can turn, so gearing is required. Each time its case rotates, the internal gear rotates many times at a faster speed.
This allows the motor to work at a faster and more efficient speed, while also allowing the wheels to spin at a relatively low speed. The main point to get across is that the gearing inside the hub reduces the fast speed of turning, allowing the wheel to turn at a more suitable speed. Tampa Bay applies a 52V geared hub motor to their electric bikes, ensuring that their products are powerful enough to ride anywhere.
