Three Czech companies worked together to develop this helicopter bike that demoed for the first time in Prague today. It went through a remote-controlled five minute flight.

This 209-pound rig with its four battery-powered propeller pods isn't yet capable of carrying a real human, so the only passenger onboard was a dummy.

The bike developers say it'll need more powerful propellers before it can sustain flight with a human on it, but with that being said it'll be impractical for many reasons, one of which include the bike's crazy width and a hefty price tag.

Plus who really needs a flying bike that risks your safety? And what happens when huge winds sweep you mid flight-cycle?
