Abstract
A wheel assembly having a motor attached to a hub within the wheel assembly such that the motor powers the wheel assembly to rotate about an axle once the motor receives a predetermined amount of power. A battery system is configured to deliver power to said motor, the battery system is arranged to rotate with the wheel assembly. A sensor system within the wheel assembly provides data related to velocity and angle of orientation of the assembly. A control system within the wheel assembly receives data related to velocity and angle of orientation of the wheel assembly from the sensor system, with the control system having at least one output to from the battery system indicative of an amount of power that is delivered to the motor.
