British inventors claim world's first flying bicycle

A pair of flight enthusiasts, John Foden, 37, and Yannick Read, 42, have devised a two-wheeled bike -- christened the XploreAir Paravelo -- that transforms into an aircraft. The British inventors say it is the world's first fully functional flying bicycle.

The machine can travel at speeds of up to 15 miles per hour on the road and 25 miles per hour in the air, reaching altitudes of up to 4,000 feet.

The flying bicycle looks like a conventional bike connected to a lightweight trailer, which houses a giant fan, fuel for the contraption's engine and the flexible fold-away wing. Both the airframe and bike are made from aircraft grade aluminum. 

The bicycle can be disconnected from its trailer for inner city use, then docks to form a 'para-trike' for take-off. In order to fly, the bike and trailer are fastened together, the wing is unfurled and an electric starter fires the biofuel-powered 249cc motor. Tired Tour de France competitors might want to consider this option before taking on a particularly daunting hill climb. 

The Paravelo needs a long stretch of open ground, clear of obstructions for takeoff. Once airborne, it can stay in the air for up to three hours. Once it's in the air, the flying bicycle's inventors say that it controls like a conventional fan-powered paraglider.

The bicycle is small enough to be taken on public transport, and the entire vehicle can be stowed in a garage or carried up stairs and stored at home.
