Cardboard Bike unveiled

This is like the ultimate green transport idea ;)

Phil Bridge, a student at Sheffield University, created a unique cardboard bicycle which aims to reduce thefts and encourage people to go greener and use "bikes" instead of cars. About his prototype, Phil said: 'The lightweight quality of the cardboard, combined with its low cost, means it is possible to create a bargain-bike that is also less susceptible to thieves. At the moment low-cost bikes are usually very heavy, which can also put people off.'

The cardboard bicycle is is made almost entirely from recyclable material and uses interchangeable mechanical parts. It is also cheap (around £15 to be produced), can be used in most weathers, but has a life expectancy of about six months.
