A Brief History of the Marque
1925-1933 Deutsche Industriewerke AG, Berlin (D-RAD)
1920-1925 Derad Aktiengesellschaft, Berlin (Derad)
The D-Rad machines developed under the direction of Martin Stolle in the thirties were extremely successful machines that were used in competition by Franz Heck, Franz Seelos, Max Polster and Paul Bülow.
NSU bought the D-Rad company in 1931 and continued production until 1933.
Many D-rad motorcycles were powered by their own 500cc sidevalve engine, and they also used Bark two-strokes. In 1923 they built a boxer with the engine mounted longitudinally.
They also built their own sidecars, and D-Rad sidecar taxis were in service in some German cities.
They exported to Poland, Bohemia, Moravia, Slovakia, the Balkan countries and other parts of the USSR. Total production was 44,500, a substantial figure in those times. (JF)

d-rad type r9
hello. My name is Andrei Banu and I am working with the Technical Museum Dimitrie Leonida in Bucharest Romania. This museum has a Type R9 D-Rad motorcycle that wishes to put out for display. Unfortunately we lack any info on the history of D-RAD and this model we own. Please be so kind to provide us with any info and pics you might be able to share. Thousand regards, AB
Bucharest , Romania
Thank you for responding to my request. Here you have the pics I own for the D-Rad. Also I have the same problem identifying few more
motorcycles - a Rudge and a Villiers with Buchet engine. Another one I have identifyes as a Peugeot P102B but I couldn't find any
history of the model or any data about it. These motorcycles (along with others that I already identified and gatherd some info) are
owned by the Technical Museum in Bucharest. Unfortunately they are in a verry poor shape and me and some friends (the Dacii Liberi club)
decided to do something abot that. At first we want to provide each bike with adequate tag displaying al the info a visitor might
request in a museum. The next stage would be trying to bring the bikes in a better shape and even make them run again. Unfortunately the
museum cannot provide any financial help so this second stage might have to wait until we can aquire the sponsorship required for the
materials and the tools we're still lacking for the job (if you know some people that might help us with these- not money, materials and
tools that are still in good shape that they don't use anymore( old grinders, paint gun, sand-blkast gun, anything at all) i'd apreciate
putting me in contact with them)
In this mail you have the pics for D-rad and the Rudge and I'll send you another with the Peugeot and the Villiers.
Thank you very much for any help you can give us.
If you have a query or information about D-Rad motorcycles please contact us
