Engineers in the Czech Republic have built a bicycle that can fly.
The demonstration does beg the question “Why a bike?”. Once those big, knobby tires are lifted off the ground, aren’t they rendered more or less moot? According to the project website, the central concept was to create a flying vehicle that could easily be ridden to a more suitable takeoff site and then be capable of a 3 – 5 minute flight. In order to offset the extra weight added by all the rotors, they could be used to help propel the bike along the ground, besides allowing it to fly.
