A bicycle made almost entirely of cardboard has the potential to change transportation habits from the world’s most congested cities to the poorest reaches of Africa, its Israeli inventor says.
Izhar Gafni, 50, is an expert in designing automated mass-production lines. He is 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.
“Making a cardboard box is easy and it can be very strong and durable, but to make a bicycle was extremely difficult and I had to find the right way to fold the cardboard in several different directions. It took a year and a half, with lots of testing and failure until I got it right,” he said.
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.
Once the shape has been formed and cut, 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.
In testing the durability of the treated cardboard, Gafni said 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.
