The invention discloses an automatic degradation variable-level variable-speed transmission bicycle, and the bicycle comprises a bicycle support; a middle shaft is installed on the bicycle support, a middle shaft chain wheel set is installed on the middle shaft, and the middle shaft chain wheel set is composed of three chain plates different in size. A rear axle of the bicycle is provided with a tower footing, a sun gear is fixedly installed on the tower footing, a planet carrier is arranged on one side of the sun gear, and a planet double-gear sub-gear is installed in the planet carrier. The bicycle is easy to start, capable of running at a high speed, diversified in function and reliable in running; the maintenance is convenient; the cost is low; the bicycle is energy-saving and environment-friendly, has a good market prospect, and brings great convenience to a bicycle rider. The characteristics of the first-stage transmission device and the second-stage transmission device are integrated, the bicycle can be easily started and climb a slope and can be ridden at a high speed, and the second-stage transmission state can be automatically converted into the first-stage transmission state in the riding slowing-down and parking state, so that it is guaranteed that the bicycle has better riding experience.
