Cardboard Bicycle Costs Just $30, Don't Leave It Out in the RainAddyDugdale6/28/08 3:00pmFiled to: Phil bridgeUltimate green machineCardboard bikeBicycleecoGreentransportBikecycle52EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkA 21-year-old student from the UK has designed a cardboard bicycle that he has dubbed "the ultimate green machine." 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.AdvertisementPhil 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".The bike is still at prototype stage, and Mr Bridge says he still needs to finalize the design. "The prototype does work but it is still quite limited and there are a few problems," he says. Rain, however, is not one of them, he claims.
