An Overview of the Simplex Marques
Italy, Netherlands, USA, Australia and Great Britain all had Simplex brands.
The Dutch Simplex was made between 1902 and 1968.
English Simplex machines were 105cc twostrokes for use on bicycles, and were made from 1919 to 1922 by Patrick Engineering
Italian Simplex motorcycles were built by Luigi Pellini between 1921 and 1950 using his own OHV engines of 149cc, 174cc, 210cc and 496cc, and after the war similar machines were produced with 148cc and 248cc engines.
There was also an American Simplex made from the late 1930s to the late 1960s, powered by small industrial engines including Clinton.

There was an Australian made Simplex also. It was nothing exciting merely being just assembled bike from the 1930's with a Villiers engine, and the usual makes of forks, wheels, gearbox, etc. To my knowledge none survive and it's many years since I saw the last one.
