Brief History of the Simplex Marques
Italy, Holland, USA, Australia and England all had Simplex brands.
The Dutch Simplex was made betwween 1902 and 1968. Early machines were fitted with Fafnir, MAG and Minerva engines, Motosacoche in the early twenties, and from the mid 1920s utilised both Blackburne and Bradshaw power units. In the late 1930s they also used Villiers (including a watercooled version) and Sachs twostrokes..
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 an 1950 using his own OHV engines of 149cc, 174cc, 210cc and 496cc, and after the war similar machines 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 its many years since I saw the last one.

Simplex Ala d'Oro WANTED
Hello, I live in USA and I am looking to buy a 1930-36 Simplex Ala
175-210cc motorcycle made in Turin, Italy. Please contact me at: whhpost
Hello, I 've sent a scanned image of a restored '37 210cc Simplex Ala d'Oro. This is exactly the model I'm looking for. I hope you can use it.
The bike in the image was from an Italian dealers website ( http://www.motoold.it ). The bike was sold in 2004, I think. These are pretty rare machines, even in Italy where almost all of them still reside. I think they never made more than 300 a year in the 30's ... if 20-30 still exist, I'd be surprised.
I am looking for this bike because it had an attractive and compact unit-construction engine which was modern for its day. Italian motorcycles in the '30's were in many ways more advanced than British machines.

message: Simplex made motorbikes from 1899 (?) to about 1950, by then actually considered mopeds. They were at one point the largest motorbike factory of holland. Simplex was based in amsterdam and also made cars. (Not to be confused by the german and us simplex).
