The invention relates to bicycles and discloses a bicycle for solving the deficiency that a self electricity generation device of an existing bicycle is unadjustable. The bicycle comprises a bicycle frame, wheel assemblies installed on the bicycle frame, an electricity generating device, a controlling device, an electricity storage device, a braking device and a braking intensity sensor, permanent magnets and induction coil components of the electricity generating device are fixed on the bicycle frame and the wheel assemblies respectively, when the wheel assemblies rotate relative to the bicycle frame, the permanent magnets and the induction coil components induct each other for generating electricity, and the electricity generating device is connected with the electricity storage device through the controlling device; the braking intensity sensor is installed on the braking device and connected with the controlling device and transmits a braking intensity signal to the controlling device; the controlling device changes the load of the output end of the electricity generating device according to the received braking intensity signal. According to the bicycle, the output power of the electricity generating device is adjusted automatically according to different braking states, the electricity generating device can help braking and deceleration, and the slight deceleration can be achieved by increasing the load of the electricity generating device.
