First, three Czech companies teamed up to make a prototype of an electric bicycle that made its first successful remote-controlled, five-minute flight Wednesday in Prague.
Weighing 209 pounds, the hefty looking mountain bike has two battery-power propellers in the front, two in the back and one each on the sides. Due to its weight, a dummy rode in the saddle for the test.
Milan Duchek, technical director of Duratec, a bicycle frames maker, says more powerful batteries will be needed before a human takes a two-wheeled flight.

The next somewhat crazier and DIY experiment — outfitting a woman’s bicycle with rocket power — was done by Colin Furze, who according to his website, is a plumber in the U.K. who hosts a YouTube channel with some of his interesting engineering feats.
The latest he describes as “an old womans [sic] bike built for shopping turned into a bomb inspired safety hazzard [sic].”
