Phil Bridge, a 21-year-old university student in the UK, has designed a cardboard bicycle that cost around $30 to make:
Supporting anyone up to 168 pounds, the frame, which costs around $6 to make, is made from the cardboard used in industrial packaging, whilst the wheels and chain are standard bike issue, and will cost around $24.
Phil Bridge, who is studying Industrial Design, came up with the idea as he was researching reasons why people don't use pedal power to get around town. "A typical round town bike can cost several hundred pounds," says Mr Bridge. "That's a large investment for people who aren't sure whether they will use it. The idea of cardboard is to completely devalue the bike".
