The "Bike Hanger" essentially works like a manually-powered ferris wheel, or a dry cleaner's rack: bikes hook up to the wheel, and are spun up onto the side of the building for storage.
As The CityFix reports, the concept is "currently being developed for Seoul and London, though the project's low maintenance cost, dedication to using recycled materials and ability to save sidewalk space make it an alluring investment for any city."
