Found this lovely design by Michael Ubbesen Jakobsen. I’m not a huge bike rider (I have my reasons) but this would definitely sway me on the whole going green thing when it comes to travel. Here’s the description:
The Baubike was designed by Michael Ubbesen Jakobsen and inspired by the designs of the Bauhaus. It is built starting from the square and the equilateral triangle. The back offers the possibility of different accessories depending on the role that each one wish. So far a prototype has already been seen in different rooms of the bike.
