See the 'world's fastest racing bike' which you have to lie on your stomach to pedal

This unusual contraption is a whole new angle on cycling - as it's a bike you ride while you're lying on your STOMACH.

The Bird of Prey is a semi-prone bike that allows you to keep your head up and see the road in front.

In development since 1991 by California-based architect John Aldridge, The Bird of Prey is more aerodynamic than a sit down bike as the shape of the rider reduces wind resistence.

The website explains: "The rider’s body is supported on the hips placing the body in a position that allows the rider to push and pull on the pedals in a fast spinning action."

Your hips are supported by soft “catcher mitt”, leather covered supports. Your elbows are supported by the aero bars at front and feet are clipped into the pedals at the rear."

The Bird of Prey also uses all standard bike parts and accessories.

On the market for around £6,871, the Bird of Prey was hand-built by master bike builder Russ Denny.

The bike is similar in style to an Englishman's invention from 1972.

Patrick Thomas, from Laleham, Middlesex, made himself this nine foot long bicycle which he rode lying on his stomach.

Pat, 72, claimed the bike gives him extra speed because there is less wind resistance
