The invention relates to a running bicycle which comprises a bicycle body, a transmission assembly arranged on the bicycle body and tires connected with the bicycle body; wherein the tires comprise afront wheel and a rear wheel, the bicycle body comprises a handrail and a frame body for containing the transmission assembly, the handrail and the frame body are connected in sequence, and the transmission assembly comprises a plurality of rolling shafts and caterpillar bands wrapping the rolling shafts. The rolling shaft is arranged in the frame body, the transmission assembly drives the rear wheel to rotate sequentially through a crawler gear, a transmission gear, a power gear and a rear wheel gear which are arranged at one end of the tail rolling shaft in a sleeving mode, and the diameterof the power gear is larger than that of the rear wheel gear. Compared with the prior art, it can be guaranteed that when the roller rotates by one circle each time, the effect that the tires rotate by several circles can be achieved; therefore, it is guaranteed that sufficient power is provided for the bicycle to move forwards, and interestingness of the running bicycle is improved.
