Wireless power transfer for integrated cycle drive systems is described. A cycle power system includes a rim that is connected to, and positioned concentrically with, a sealed housing that can rotate about an axis. The cycle power system also includes an integrated drive system disposed within the housing. The integrated drive system includes a battery and a motor for driving a cycle by causing rotational movement of the rim about the axis. Additionally, the cycle power system includes an inductive structure that is disposed within the housing, and that wirelessly charges the battery through induction between the inductive structure and remote a charging station.
