Abstract

The invention discloses a bicycle structure which comprises a frame and a front wheel. The frame comprises a hollow axle, a rear axle bracket fixed to the rear end of the hollow axle and a middle axlebracket fixed to the front end of the hollow axle, the hollow axle is arranged in the length direction of a bicycle, a rear axle is fixed to the rear axle bracket, a rear hub is installed on the rearaxle, a front axle sleeve rotationally sleeves the hollow axle, a slide bar is arranged at the rear end of the front axle sleeve, a rear axle sleeve is slidably installed at the rear end of the frontaxle sleeve through the slide bar, the hollow axle is internally provided with a hollow inner cavity, a first motor and a battery are installed in the hollow inner cavity, the battery supplies electricity to the first motor, and an output end of the first motor is connected with a screw. According to the bicycle, by means of creative structural design, a necessary chain in a traditional bicycle transmission structure is removed, the structure is simplified, a variable-speed control structure is arranged in a hollow pipe fitting, and the structure is further simplified.
