Professor Lutz was later acknowledged for the work he had done relating to jet engines and two-stroke engine technologies and became a respected figure in aviation research. Professor Lutz died in 1974 and now his personal Lutz P53 moped has become part of the Städtisches Museum Braunschweig collections.

In the beginning, the company developed an efficient bicycle engine that could be easily installed in the frame of any bicycle's brands at that time. The engine was a 58cc 2-stroke as authorities limited new designs to less than 60cc.

The engine was also used to power wheel-chairs, lawnmowers, pumps and all manner of stationary machines. It's noted several other companies including Goebel, Delius and Adria used this engine. As a result, some 2,000 of these 48 cc (b/s 40/39.5mm 49.3cc) machines are sold in 1951.

And then, Lutz GmbH developed several motor scooters, examples of which competed in the ADAC Deutschland Rundfahrt reliability trial. Besides that, Lutz also developed and marketed the moped.

Its first scooters appeared in 1949 wore basic lightweight bodywork construction made it rather similar to the early Italian machines and named 'Lutz R3 Hummel' using a 58 cc 2-stroke engine.

In 1950 the company got into trouble because it gave the standard vehicle name of the 'Hummel,' and the compatriot company DKW raised objections due to feeling have more right to the name, as a result, the Hummel name should be removed.

The following year Lutz produced a larger scooter named 'Lutz Autobahnroller' with a 175cc engine and designed by W. Lieb in a bizarre round-shaped. It was similar in appearance of the smaller model by retained the two-speed gearbox and used 8-inch wheels. The Autobahnroller engine claimed able to spew power up to 7 horsepower and made it could run-up to the speed of 80 kph.
