In 1951, it began manufacturing motorized utility tricycles with 50–100cc engines and an unconventional design in which the solo wheel was located at the rear.
Mego subsequently designed and built a large number of 50cc moped and motorcycle types and light 50cc three-wheel trucks, using mainly Sachs engines, as well as bicycles.
Mego's moped and motorcycle models, featuring innovative designs, included the 50S series, the EK, the Libra, the Viva and the particularly novel GP50 Carrera.
Since 1992 the company also branched in a new venture, creating subsidiaries in Japan, the Dominican Republic, Venezuela, and China, marketing and selling motorcycles.
A world headquarters of Nipponia was subsequently established in Athens responsible for design, engineering, marketing and quality control for motorcycles built in Shanghai, China.
