Cardboard bicycle

Cardboard bicycle

A Cardboard bicycle is really interesting you can carry it every where you go and it's pretty easy to commute with it. I really hope it is really durable as mentioned by the inventor.

Izhar Gafni, 50, an expert in designing automated mass-production lines. He is also an amateur cycling enthusiast who for years toyed with an idea of making a bicycle from cardboard.

He told Reuters during a recent demonstration that after much trial and error, his latest prototype has now proven itself and mass production will begin in a few months.

Cardboard, made of wood pulp, was invented in the 19th century as sturdy packaging for carrying other more valuable objects, it has rarely been considered as raw material for things usually made of much stronger materials, such as metal.

He said that first the shape of the parts should be formed then cut. Then the cardboard is treated with a secret concoction made of organic materials to give it its waterproof and fireproof qualities. In the final stage, it is coated with lacquer paint for appearance.

Gafni said to test the durability of the treated cardboard he immersed a cross-section in a water tank for several months and it retained all its hardened characteristics.

Once ready for production, the bicycle will include no metal parts, even the brake mechanism and the wheel and pedal bearings will be made of recycled substances, although Gafni said he could not yet reveal those details due to pending patent issues.

The bicycles are not only very cheap to make, they are very light and do not need to be adjusted or repaired, the solid tires that are made of reconstituted rubber from old car tires will never get a puncture, Elmish said.
