An ultralight trike is a type of powered hang glider where flight control is by weight-shift. These aircraft have a fabric flex-wing from which is suspended a tricycle fuselage pod driven by a pusher propeller. The pod accommodates either a solo pilot, or a pilot and a single passenger. Trikes grant affordable, accessible and exciting flying, and have been popular since the 1980s. Trikes are referred to as "microlights" in Europe. Such aircraft are also known as 2-axis microlights, flex-wing trikes, weight-shift-control aircraft, microlight trikes, deltatrikes or motorized deltaplanes,
