Diamant historical snippets
1903-1935 Diamant Fahrradwerke (Elite-Diamant), Brand-Erbisdorf 1
Established as a bicycle producer in 1885 by the brothers Friedrich Wilhelm and Wilhelm Friedrich Nevoigt, the factory was located near Chemnitz. The company name in later years became Elite-Diamant and motorcycles were marketed as both Diamant and Elite. Diamant is now the oldest bicycle firm in Germany
Motorcycle and tricycle production began early in the century using Fafnir and their own V-Twin engines. This was curtailed in 1907 or 1908.
In 1926 Diamant resumed production with 350cc single-cylinder models powered by OHV engines from Kühne - these are regarded as the best machines the firm produced. These were designed by Franz Gnädig, who was previously a partner in the famous K.G. Krieger-Gnädig firm.
Diamant was purchased by Opel in early 1928, but the two firms parted company in 1930, Diamant becoming Elite Diamant AG.
Diamant built motorcycles powered by 75cc and 100cc Sachs two-stroke engines until 1935.
During WWII the factory employed a great deal of slave labour, mostly from the Soviet Union. The company was nationalised in 1952 and under the DDR continued to produce bicycles, some of which were quite advanced. They won the bicycle world championship in 1959 and 1960. Sometime after the collapse of the Soviet Union the company was acquired by a Swiss concern, which was later purchased by the Trek corporation in the United States.
A report on the Paris Salon of October 1922 reads:
"La Francaise Diamant - Probably the neatest machine of its type in the Salon. Frame embodies welded tank. Two-stroke engine with integral reduction gear, final drive by enclosed chain, 1 to 1 ratio. A lady's model on similar lines is also shown."
1. Some sources give a closing date of 1940.

1938 had a 98cc Sachs
Hello, my name is Mohammed Javid Hussain, I find your website where is some info about DIAMANT motorbike. I live in Sharjah United Arab Emirates and Indian National. I would like to know everything about DIAMANT motorbike, coz my father had DIAMANT about 40 years ago which was declared crowd puller bike one and only piece in India in such emasculate condition. The Sport of 1938 had a 98cc Sachs and came in different styles, but few details are known, during the war they even made a wood burning engine. And I have few awards winning collection of other motor bikes like MILITARY TRIUMPH, TWIN TRIUMPH, and I have little pictures of DIAMANT, some documents, and small ornamentation hand from motorbike. If you have some other info about DIAMANT or pictures please send it to me.

Your note has been posted on the Diamant page at the European Motorcycle Universe web site. We just noticed that the link to your site no longer works. Is there a new link? Or could you send me the info and photos and I could post them on the page?
January 6, 2003
That's right, that my old link no longer works.
There is new link, to new page, unfortunately only in polish language.
There is some information, and story (How can I start adventure with Diamant motobikes), about Diamant motobikes, and also AWO-SIMSON-SPORT, which I have now. And some other info, about other old motobikes.
If you want, I send you these information which I have, but they are not many, like the photos.
The new link is http://www.motocykle.krakow.prv.pl 
Thanks for the interest this problem.
With best whishes
