The single seat Airbike was designed to meet the requirements of the United States FAR 103 Ultralight Vehicles, including the maximum 254 lb (115 kg) empty weight. The tandem-seat model was intended to be licensed as an ultralight trainer or an amateur-built aircraft.
The single-seater can achieve an empty weight as low as 251 lb (114 kg) with the use of a light-weight engine, such as the 28 hp (21 kW) Rotax 277 or the 22 hp (16 kW) Zenoah G-25.
The name Airbike was chosen for the aircraft because it has a narrow fuselage and the pilot’s feet rest on rudder pedals that are on the outside of the aircraft, in a similar manner to a motorcycle
