Monark, a manufacturer of bicycles and motorcycles that like Husqvarna and Crescent and many others Swedish manufactured their first moped according to the new law that came 1952. Their "monarped" was very much like a motorcycle with the the tank in the "right" position and a telescopic front suspension. Monark most often used Ilo engines but Pilot, Nsu and Husqvarna (more?) was used also.
The name monark was used several years after 1963 when Monark, Crescent and Husqvarna joined in MCB. However in the period 1963-1968 almost all models used Husqvarnas E-engine.
