Are you concerned about high gas prices? This could be a revolutionary invention that could bring a new twist to an old means of transportation. Izhar Gafni has perfected a bicycle made almost entirely of cardboard. Gafni is an expert in designing automated mass-production lines. He is an amateur cyclist and for years had toyed with the idea of making a bicycle from cardboard.

After 18 months, with lots of testing and failure, Gafni got it right. Once the shape has been formed and cut, the cardboard is treated with a secret concoction to give it it's waterproof and fireproof qualities. Then it is coated with lacquer paint for appearance.

Once the bicycle is ready for production, the bicycle will include no metal parts. Gahni and his business partner Nimrod Elmish say they plan on the cardboard bikes to be made on a largely automated production line and could be sold for about $20. The bikes need no maintenance and no adjustment. A car timing belt is used instead of a chain and the tires do not need inflating and can last for 10 years. An urban version of the bike will have a mounting for a personal electric motor.

They hope to have the planning complete for the first production lines in six months.
