Flying cars are yet to take off - could bikes have a better chance?
Researchers in the Czech Republic have unveiled a 95kg (210lb) remotely-controlled bicycle that can hover a few metres above ground for five minutes.
Carrying a dummy rider, the electric prototype successfully took off, flew around and landed inside an exhibition hall in Prague.
The bike is powered by two battery-run propellers on the front, two on the back and one on each side.
The machine could help two-wheeled commuters avoid zigzagging through traffic jams - but it is not quite ready to hit the road - or the air above it - just yet.
The batteries only allow for a few minutes of flight before needing to be re-charged.
"Because the capacity of batteries doubles about every 10 years, we can expect that in the future the capacity would be enough for the bike to used for sports, tourism or similar things," said the technical director of Duratec Bicycles, Milan Duchek.
空飛ぶ自動車はすでにあるので、次はバイク。
バッテリー式ということもあって５分間のリミットがある。
しかし、バッテリー容量は１０年で倍の密度になっているので、１０年経てば１０分飛べるようになるというようなことらしい。
