I remember the Itera plastic bicycle from the 1980's. It was promised to be feather light yet stronger than a steel bicycle but ended up heavier than steel and flexible enough to be difficult to ride. I'm really supportive of alternative bicycle materials and design. Rideable bicycles have been made of wood, bamboo, steel, aluminum, titanium, magnesium, beryllium, carbon composite and ceramic metal matrix. Building a bicycle out of any new material is a difficult engineering exercise. No mater how green the cardboard bicycle is it won't change the world if nobody wants to ride it. I'd rather mate the cardboard frame with conventional wheels to make it practical even if it turns out more expensive and less theoretically green.
@GIANT-STEPS: You're correct, and I agree, but the idea is to make as "green" a bike as possible. While he doesn't come clean on the subject of the chemical make-up of the (epoxy?) coating he uses to treat the cardboard, he does say it's biodegradable and the tires are old automobile tires that have been reused as the bike's tires.
In the end, the cause is more a laudable one than an effort to provide a long-term solution or product. I think it's great! For $20, I can figure out if I like cycling enough to spend $2,000, or more, on a really nice bike. Plus, once the bike "breaks down," (supposedly) it's all recyclable. I really like the idea of that!

The only thing that troubles me is the solid tires. The best way I've found to make a bicycle ride badly is to put solid tires on it and the better solid tires are made of urethane instead of rubber. If I could modify it for pneumatic tires it would be worth a try.

Yeah man, love the idea, thinking out of the box (heh, heh). Seriously, though, anything getting more people out on affordable bikes is a good thing. With solid tires, though, I would expect the ride to be a little bit harsher than most.
