The invention discloses a shared bicycle stereo garage which mainly comprises a rope winch, a synchronous shaft, a driving motor, a lifting rope, a fixing rope, a fixed bottom plate, a plurality of sets of rack columns fixed on the fixed bottom plate, frame lifting slide blocks arranged on the rack columns and bicycle storage racks fixed to the frame lifting slide blocks. Each layer of bicycle storage racks can respectively store a plurality of shared bicycles respectively, the driving motor is controlled to work through a control system, the driving motor drives the rope winch to rotate, therope winch rotates to adjust the length of the lifting rope so as to control the lifting of of the bicycle storage racks, and multiple layers of stacking and storage of shared bicycles are achieved. The shared bicycle stereo garage is simple in structure and convenient to use, the construction difficulty is small, and the problem is effectively solved that urban public space and sidewalks are occupied by shared bicycles parked disorderly. In addition, the manufacturing cost is low, the floor space is small, and the garage capable of accommodating 60 shared bicycles has the manufacturing cost of less than 10,000 yuan and takes up a dozen of square meters of floor space.
