Wheely Good

Fold-up bikes are a very good thing and a blessing to commuting cyclists but even the trusty Brompton is a tad unwieldy digging into people's thighs on the train and looking a little like a baby Transformer in mid-transform. So thank heavens for young design talent because Dominic Hargreaves - yes, the one who wants to park up your wall - has designed a fold-up bike so nifty, the entire frame fits inside the diameter of the wheel and can be pulled along by the handlebar - a whole new twist for the concept of the wheely. "The Contortionist" bike is in the running for the Dyson Award for student designers and it's certainly sleek, clever and efficient (watch a demo here) but we can't help liking the funky Locust better, even though it doesn't exist in the real world yet.
