Stereo bicycle library

The invention discloses a stereo bicycle library. The stereo bicycle library comprises a first circular rail, a plurality of transport mechanisms and connecting members, wherein the first circular rail is fixed above the ground; each of the transport mechanisms includes a first transport vehicle, a first hoist and a chain, wherein the first transport vehicles move along the first circular rail; the first hoists are mounted on the first transport vehicles; rollers of the first hoists are wound with the upper ends of the chains; one ends of the connecting members are connected to bicycles, and the other ends of the connecting members are detachably connected to the chains; and each of the chains in the stereo bicycle library can be connected to a plurality of bicycles through the multiple connecting members, and the first hoists can hoist the multiple bicycles in sequence through the chains, so that the utilization rate of the vertical space is improved, and the technical problem that the bicycles occupy a larg
