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".

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.

Made of carbon composite, the handlebars, stem and fork are all one piece, with the ergonomic seat post and saddle integrated into the frame. Handlebars connect to frame via a pivot, and the seat even has a hole in it in case you get taken short while cycling to keep you cool while you work the pedals.

The Y-frame shape means that the Oryx is shock-proof and keeps you in contact with the road at all time, and there is a one-sided fork and chain-stay. The crank is designed like a ring and mounted inside the frame on a couple of ball bearings, and the wheels detach from the bike at the push of a button, a useful time-saver for competitions.
