Life
Riedel studied mechanical engineering and worked in the 1930s first for Ardie and then for Victoria . During the Second World War he developed a starter motor for the first German jet engines . The twin-cylinder two-stroke - boxer engine had a displacement of 270 cc and a power of 8 kW (11 HP) at 7,150 min -1 . It was designed as an extremely short stroke ( bore × stroke : 70 mm × 35 mm = 2: 1) so that it fit into the hub of the turbine compressor. It had an integrated planetary gear for reduction . It was produced by Victoria in Nuremberg and served as a starter for the Junkers Jumo 004 and BMW 003 jet engines .
In 1947, Riedel in Immenstadt the Riedel engines to the constructed him AG light motorcycle Imme R 100 to manufacture in series. By the end of production in 1951, around 12,000 units had been built. In December 1949 he began designing the Riedel Till scooter , which, however, was no longer in production due to the bankruptcy of Riedel Motoren AG in October 1951. An "Imme" with a two-cylinder engine was also in development.
After Riedel Motoren AG went bankrupt, Riedel went back to Victoria and developed the Victoria Swing models and the 200 cc two-stroke scooter Victoria Peggy . The "Peggy" was equipped with a new type of electromagnetic push-button circuit, electric starter, fan cooling and a rear-wheel drive unit. The "Swing" was also equipped with a push button circuit ( draw wedge ).
Norbert Riedel died in an avalanche accident in 1963.
