Researchers from several Czech companies have managed to make a bicycle soar with the aid of six electric motor-driven propellers. Looking like an over-sized quadrocopter drone, the bike was actually guided in a similar RC manner by scientists on the ground while a dummy rode in the pilot's seat. The range of the contraption was severely limited by the small batteries needed to keep the already-chunky 220 pound weight down, and the device would obviously be difficult to operate on a bike path due to its ungainly size. Still, the developers said the project was more about the fulfillment of childhood dreams than any commercial aim -- though we're not sure even our wildest ET fantasies would compel us to make the leap.
