This bike hanging on the wall is actually a shelf and it is called Bike Shelf and is designed by Chris Brigham for Knife and Saw. The San Francisco-based designer got the inspiration for this shelf after visiting several friends living in small spaces in New York. He noticed that their bikes were always in the way, in the hall or leaning against another piece of furniture. Chris Brigham realized that there were no intelligent solutions to the problem.
This shelf is made out of solid walnut or ash and is suspended from a square steel rod mount. The Bike Shelf management system provides a compact storage solution for bicycles while its flat top surface acts as a shelf for keys, books or bike accessories. I think this idea is so genius, and a great solution to a problem that a lot of people have. Why not find something that looks great and is functional at the same time? (A specially if you own a cool, yellow bike that you wouldn't mind hanging on your wall...)
