Three companies in the Czech Republic have collaborated on a prototype bicycle that is also capable of flying.
Currently in the test phase, a mannequin is placed on the bike while it is controlled remotely like a model aeroplane.
But in the near future a human will sit on the bike, and control it from there, according to developers.
While on the ground the bike is pedal-powered, and in the air it is powered by a battery, which currently limits flight time to 5 minutes.
