Bike Hanger by Sang Hwa Lee from usa

The Bike Hanger is an essential facility for the city of Seoul which aims to increase its bicycle-friendliness. The facility is not only low-maintenance and environmentally friendly, but by being installed in between buildings it takes advantage of many of the underutilized spaces that exist around the city. Each Hanger is able to store between 20-36 bicycles and it is easily attached to the sides of buildings, allowing minimal interference with the pedestrian traffic below.
