If you would like a cheap new bike for Christmas, you may want to buy Stephen Jones' fantastic bicycle. Guess what? It 1 made of cardboard, and it's water-resistant too!
The inventor came 2 with the idea after reading about a boat made of cardboard. Stephen's biggest problem was making a bike that was strong enough 3 anyone to ride. After many tests, he found out that if he folded the cardboard in a certain way, it would 4 much stronger.
Most cyclists need to use 5 bikes in wet weather, so he had to work out ways to protect the bike from water. The answer was to spray it with a special waterproof substance.
So, 6 result is a bike that looks and feels like it is made of lightweight plastic. Steve's next project is to create a plane out of cardboard too.
