During World War 11 Norbert Riedel had designed a two stroke starter engine for the first **LUFTWAFFE jet fighters.After the war he moved into motorcycle design,he’s first design was the Riedel R100.The American army desperately wanted his jet starter engines ,so gave him the production tools and equipement which could be used for motorcycle production.His R100 was design with some restraints in place. ie it had to be cheap,easy to build,and he only had about 75% of the raw materials he needed(all of Germanys steel works were bombed by the RAF)The frame and fork tubing is all the same diameter. The egg- shape(ellipsoid) engine 99cc and 4.5BHP.The cylinder and the head were one piece.The transmission had no neutral,the clutch lever could be held withdrawn by a clip!.Only one front fork leg and the rear leg is also the exhaust pipe,3 speed handlebar gearchange(engine goes up and down with the rear wheel)Around Christmas 1947 Riedel started the first test drives
In1948 Riedel found a production factory in IMMESTADT(Bavaria).IMME is a German word for BEE,and the logo and name for the motorcycles were found.Production started in 1949,but only 80 were made in the first year.In 1950 numbers had reached 1,000 a month ,although the motorcycles were selling well! there even plans to make the Imme in London under licence!! the works had some financial and warranty problems and the IMME AG went out of business.The numbers of R100 built was around 12,000 today they are very rare bike in Germany(update December 2014,just seen about 23 running*** look at video, you will notice same riders about 3 times held at a Treffen in October 2014) and only 1 in the UK.Riedel had designed a new egg- shaped twin 150cc engine,plus a scooter named the ‘Till’ and had planned a comeback with an improved version of the IMME.But in 1951 the factory was shut down again.
Later Norbet Riedel worked for Triumph and Victoria in Nurnberg one design was the Victoria ”SWING’ which had a electric operated gear box having 4 push buttons on a panel attached to the lefthand handlebar.He died tragically in a avalanche whilst skiing in 1964, aged 50 years.

In Germany there 2 clubs devoted to the Imme, http://www.imme-freundeskreis.de(circle of friends) and a club in the town Immestadt called DER IMME SCHWARM e V so the picture above is a swarm of IMME’s. (bees).Note the leader of the pack is riding one of the last versions of the R100 with its separate exhaust system from the frame.
Immestadt,is a small town in the southwest of Bavaria set amonst the Bavarian alps.One of the bergs that overlook the hamlet is the ‘Grunten’ the plaque is to commemorate that someone actually rode a IMME to the top of the 1738meter high berg.
