The Mosquito was conceived in 1946 in the design offices of Garelli, a Milanese company founded in 1919 by Adalberto Garelli, a brilliant engineer and pioneer of the two-stroke racing engine. The idea was simple and revolutionary: to design an auxiliary engine so compact and lightweight that it could be fitted to any existing bicycle without modifying the frame or the drivetrain. The result was the Mosquito, a 38cc single-cylinder two-stroke engine mounted on a cradle attached to the frame, driving the front wheel via a small friction pulley. A solution of remarkable mechanical elegance, produced in millions and exported worldwide.
The 38-B version is the direct evolution of the original 38-A. Garelli refined the mechanics, improved reliability and perfected the mounting details – corrections based on early user feedback that made the 38-B a more accomplished and robust proposition than its predecessor. Still 38 cm³, still the same friction principle, but executed to a higher standard.
1950 was the Mosquito’s heyday. The machine was at the heart of a Europe rebuilding itself and rediscovering freedom of movement at a time when this small engine represented far more than a mere mechanical accessory for many.
