Manifesto Architecture proposes a new vertical structure for bicycle storage for underutilized facades. "The bike hanger" will be made of recycled materials - metal, plastic and carbon frames. Each hanger can hold 20-36 bikes. The mechanics are powered by the cyclist at the base of the installation. "The human generator" helps turn the wheels within the structure, rotating the bikes until the owner's bike is released. Installations are schedules for Seoul and London.
