The first bicycles were made of wood. After that, manufacturers used steel tubes. But the steel ones cost too much. The people in poorer countries want to have cheaper ones. Izhar Gafni had an idea to make a cardboard bicycle able to support the weight of a human being. After three years hard work, he succeeded in creating this special bike. It is made of cardboard and 100% recycled materials. It costs less than $12. The cardboard bike can hold a rider weighing up to 485 pounds. And if you don’t want to have it any more, you could just throw it into dustbin. And this will do no damage to the environment because it is easy to recycle. When talking about his design, Izhar says, “It’s strong. It’s durable. It is cheap. What I like about it the most is: it’s made out of recycled cardboard. 小题1:What was the first bicycle made of ?
