The electric power-assisted bicycle is technically characterized by comprising different types of small variable-frequency direct-current and alternating-current motors and generators, different types of gears, inner and outer gear rings, a chain, a transmission shaft rod, a crank and a bicycle fork frame, and various components and parts including a sensor, a chip component, a power battery, an inverter, a transformer, a rectifier, a microprocessor, a commutator, a controller and a junction box are preferably symmetrically/asymmetrically arranged on the two sides of the frame and at different positions of a wheel rim and a bearing according to design requirements. The wheel rim of the electric vehicle runs through manpower pedals or a motor electric crank gear disc, a chain, a gear belt, a transmission shaft rod, a front wheel rim bearing gear and a rear wheel rim bearing gear.
