Frame winner

A final-year student at Brighton University has won a top design award for finding a way to stop bikes crashing to the ground when they are leaning against walls.

Jamie Douglas has designed the Ninety Bicycle with a 90^o rotating handlebar that flattens the bike's profile into a single linear form, making it more secure when propped up.

Douglas said: 'The idea came to me after three years of living in student accommodation and bashing into handlebars of bikes propped up in narrow corridors. I collected quite a few bruises. The new design tucks the handlebars flat. It prevents many collisions and stops bikes falling over. I ride the bike all the time and it works.'

The Ninety Bicycle, which bridges the gap between folding and fixed frames, also includes a new security system - a lock concealed inside the seatpost that complements the chain guard. It doubles as a D-frame locking device.
