The Contortionist: the ultimate fold-up bike

Fold-up bikes are great in theory but irritating in practice – once you've folded them up you've got this huge lump to drag around. Dominic Hargreaves' Contortionist bike could solve that.

The 24-year-old's design features a frame which fold up into the wheels. When the bike is folded, the wheels will still roll meaning you can easily pull it on to the train or get it on to the bus.

Vaccuum designer magnate and serial inventor James Dyson has called the design "ingenious". In fact, The Contortionist is up for the James Dyson Award for new inventions which is worth £10,000 in prize money.

Even if The Contortionist doesn't nab the prize, Hargreaves plans to start selling the bike for £400 from next year. I'd buy one, would you?
