Fly Bikes: No Longer Sci-Fi—British Inventors Make Them a Reality

You can actually buy a flying bicycle. It sounds like science fiction, but British inventors John Foden and Yannick Read have created one: the XploreAir Paravelo. Combining a foldable bicycle with a lightweight trailer housing a biofuel-powered fan engine, it can take flight with a long enough "runway," reaching speeds of 25 mph and heights up to 4,000 feet.
