Science Buzz Phil Bridge, a young design student from the UK, has created a cardboard bike. While he has yet to finalize the design, citing that there are still a few problems to work out, he expects that the final product will look much like what is pictured below. With a frame made entirely of cardboard (the wheels are standard rubber and metal), the bike can support anyone up to 168 pounds. The bike costs $6 to make and is expected to retail around $24. Purdy damn cool, and the shit’s green as hell.
