Obviously the Mosquito was designed and built
in Italy. However, it was also built under license
in France and Britian. After the Velosolex and
the VAP, it was the 3rd most popular French
At age 22, Adalberto Garelli received a degree
in engineering and dedicated his work to developing
and perfecting the 2-stroke engine for Fiat.
He quit in 1911 due to Fiat's lack of enthusiasm
for the 2-stroke engine, and continued his own
engine design between 1911 and 1914 which resulted
in the 350cc split-single. Garelli worked for
other motorcycle manufacturers from 1914 to
1918 during which time he won a competition
organized by the Italian Army to design a motorcycle
with which he used his 350cc split-single engine.
After WWI Garelli began to produce motorcycles
in his own factory. The Garelli 350cc split-single
stayed in production until 1926 and made a major
impact in racing. By 1928 his motorcycle interest
was waning and his factory began producing military
equipment leaving motorcycle production completely.
After WWII, military equipment was no longer
needed and Garelli introduced an engine called
the Mosquito. The Model 38A began in 1946 as
a clip-on engine for a bicycle frame. The concept
was a huge success over two million of the engines
were sold worldwide. Power was delivered to
the back wheel via a friction wheel and was
able to reach a top speed of 20mph.
They opened a branch in France too. In 1952,
an endurance run illustrated the reliability
of the Mosquito, with continuous use for 55
days. The Mosquito Model 38B. introduced in
1953, was a 48 cc engine; while the final attachment
engine, in 1955, had a special automatic transmission.
