A group of Czech engineers and designers have successfully test flown via radio control a proof of concept hybrid bicycle/multi-copter, the FBike, at an exhibition in Prague, Wednesday. The group says they hope to perform a manned flight at a future date. Early design specifications made available last year included lithium-polymer batteries powering six electric motors together capable of producing 50 kW of power. Thrust is delivered by two sets of counter-rotating blades mounted fore and aft, and two stabilizing rotors on the left and right side. The design includes most of the limitations a skeptic might anticipate, including limited flight times (currently estimated at three to five minutes), limited redundancy, and limited real-world usefulness as a bicycle due to its roughly 200 pound weight. ... All of which may be of little concern to the bike's designers.
