The invention discloses a wall-mounted type double-layer bicycle parking system. The wall-mounted type double-layer bicycle parking system comprises parking modules A with power, parking modules B without power, a bicycle locking module and a steel wire rope for linking among the parking modules A and the parking modules B, wherein one parking module A and the two parking modules B at the two sides are connected through the steel wire rope to define a parking device A; one parking module B and the parking modules A at the two sides are connected through the steel wire rope to define a parkingdevice B; the parking device A and the parking device B are alternatively distributed and mounted on a wall; each parking module A comprises a guide rail A, a drive slide rod, a supporting rod, a supporting rod slide block and a lifting mechanism; and each parking module B comprises a guide rail B and a driven slide block; the drive slide block of each parking module A and the driven slide block of each parking module B are linked through the steel wire rope; while the parking device A is used, the parking modules B can be lifted, and therefore, mutual interferences are effectively avoided, and a bicycle storage space utilization rate is increased.
