A power wheel is provided. The power wheel includes a wheel, a power-driving device, and a power supply for the power-driving device. The power supply and the power-driving device are fixed on the wheel. A power supply device such as a rechargeable battery is set in the wheel to fully utilize the space in the wheel. The power wheel is applicable in an electric bicycle, so that a body design of the electric bicycle is not influenced by mounting conditions of the rechargeable battery device, and a body structure of the electric bicycle is greatly simplified, thus being beneficial to the design and production of electric bicycles having varied types. At the same time, the power wheel device having the rechargeable battery set in the wheel enables the gravity center of the electric bicycle to be depressed, thus keeping the balance of the electric bicycle.
