Israeli inventor Izhar Gafni says he ready to mass-produce a 20-pound bicycle made of cardboard. There are no metal parts. The chain is actually a car’s timing belt and the tires are made from reconstituted rubber. The cost? Twenty bucks.

From Endgadget:

Izhar…spent 18 months just folding the material every-which-way in order to discover a strong enough design, and now he claims his technique is almost ready for mass production. His maintenance-free bike uses a “secret” mix of organic materials to make it waterproof and fireproof, and is then lacquered to give it a friendlier appearance.

“It’s strong,” Izhar says. “It’s durable. It’s cheap.”

This video about Izhar’s project is a great look into a maker’s mind at work.
