The invention discloses a tree-like spiral bicycle garage, mainly comprising a first-layer parking device, a center rotation mechanism and a second-layer parking device, wherein the first-layer parking device and the second-layer parking device are connected through the center rotation mechanism, so as to realize rotation of the second-layer parking device and dispatch of bicycles on the upper andlower layers. In the parking device, the gravity of the bicycle and the frame is balanced by a balancer and a fixed pulley, so as to help the user erect the bicycle and lift the frame; and a three-point fixing mechanism on the parking device prevents the bicycle from toppling over. The frame is placed spirally around the center shaft and staggered from the bicycle handle skillfully and naturally,so as to make full use of the space. With a simple and compact structure, the tree-like spiral bicycle garage disclosed by the invention changes existing bicycle parking way, can realize erecting andstoring/taking of the bicycles with different specifications and dimensions on the upper and lower layers, has the characteristics of high space utilization rate, safety, no maintenance and the like,and is suitable to be applied and popularized to the places such as communities and schools.
