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.

A smart bicycle is disclosed, which includes a battery module, a controller connected to the battery module, and a linkage device that is configured to electrically adjust the height of the saddle and/or the handlebar under the control of the controller. The smart bicycle effectively overcomes the inconvenience of manually adjusting the height of the saddle and/or the handlebar, improves comfort for riders of different body types, and enhances safety during riding.

The present invention provides a self-powering warning device comprising a driving wheel and a fixing component. The driving wheel has at least one powering module and at least one light-emitting module provided therein; the powering module can generate an induced voltage for driving the light-emitting module, and the fixing component can be mutually assembled with the driving wheel and provided on a vehicle, so as to rotate the driving wheel when the vehicle travels and drive the light-emitting module, thereby generating the induced voltage for providing an electrical energy to the light-emitting module, and thus generating an illuminating and warning effect.

A mobile induction and power-generation device includes a disc-shaped magnet, a block magnet, and a coil. The block magnet has at least one magnetic pole set each having two adjacent magnetic poles with opposite polarities, and the at least one magnetic pole set moves along a movement trajectory relative to the disc-shaped magnet. The coil is disposed adjacent to the disc-shaped magnet or the block magnet, is induced by an alternating magnetic field generated by the movements of the disc-shaped magnet or the block magnet, and generates an induction current due to the alternating magnetic field.
