  "textContent": "A wheel hub capable of being coupled to an axle of a wheel such that the wheel hub is rotatable around the axle. The wheel hub includes a housing adapted to be rotatably supported on the axle, a motor including a stator (42) and a rotor (40) , and a battery module (32). The stator(42) is adapted to be fixedly connected to the axle. The rotor (40) is connected to the housing via a transmission mechanism (19) . Both the battery module (32) and the motor are located inside the housing, but the battery module (32) is placed external of the motor. Since the battery cells are located outside of the motor in the wheel hub, there is provided great flexibility to the number of battery cells installed in the power wheel.",
