Firm from Czechoslovakia design velocipede with six propellers that can make brief hops off the ground and stabilize itself in all three axes while in flight. Theoretically, the FBike (it’s called the “FBike”) uses two main lift fans along with two side-mounted propellers to enable vertical take-offs and landings and three-axis control. It’s all electric, but the battery system is minimal: expect just three to five minutes of flight time at 30 miles an hour. Maximum speed, not specified as aerial or terrestrial, is 50 km/hr (31 mph). The bike still weighs in at a hefty 85 kilograms (187 pounds) without a pilot – too heavy to be licensed as an ultralight in the U. S. Maximum loaded weight will be 170 kg (374 pounds), something drivers will not want dropping from the sky onto their car roofs.
