Cardboard BikeA student from Sheffield Hallam University developed a kind of cardboard bicycle. It all started when Phil Bridge, of Stockport, realized that a typical bicycle is too expensive. The frame of the unique bicycle is made of cardboard and costs only 3 Pounds. With the wheels and chain added, the price of the whole bike will be at most sold at 15 Pounds, which he thinks to be cheap enough for everyone to buy, and can also prevent being stolen.
