A bicycle built out of cardboard.

A bicycle made from cardboard that costs only $9-$12 to build sounds unlikely. But, as surfaced on the blog Kottke, designer Izhar Gafni got it in his head to make just that. After three years to perfect the design, the Alfa was born.

It looks like a bike, rides like a bike, and at 20 pounds, can hold a rider of up to 485 pounds in weight.
And hey, when you're done with it, you could practically throw it in the recycle bin. The design itself is made of cardboard and 100% recycled materials.

As described on the Giora Kariv Productions video, "Izhar cardboard bike project," Gafni first had the idea when he heard of a canoe crafted from cardboard. Although engineers told the bike enthusiast it was impossible, Gafni realized that like origami or tearing phone books, "You fold it once, and it's not just twice the strength, it's three times the strength."

The video was made six months ago and is starting to get some attention on the Web. The short film follows the ingenious design process, from figuring out how to use the cardboard, to creating a clunky prototype that looks like a UPS shipment with wheels, and finally to the finished prototype. You can see Gafni take it for a spin in the video at the 4:39 mark.

The designer says of his creation, "It's strong, it's durable. It's cheap. What I like about it the most: It's made out of cardboard."

It certainly got our attention.
