The invention provides a self-electricity-generation bicycle, and belongs to the field of bicycles. The self-electricity-generation bicycle comprises a frame, a front wheel and a rear wheel. The front wheel and the rear wheel each comprise an inner hub and an outer hub. A front fork and a saddle are fixed to the inner hub of the front wheel and the inner hub of the rear wheel respectively. The frame is connected with the front fork and the inner hub of the rear wheel. A chain wheel is connected with a rear axle free wheel through a chain. A concentric reducing gear arranged on the rear axle free wheel is meshed with inner teeth on the inner circumference of the outer hub of the rear wheel. The inner hubs and the outer hubs of the self-electricity-generation bicycle are connected through bearings. Each outer hub rotates around the corresponding inner hub. An electric generator rotor with a magnet is arranged on each outer hub. A stator with a coil is arranged on each hub. The bicycle is firm, durable in use and capable of ensuring night riding illumination.
