Neumann-Neander designed and built a series of unusual prototype and racing motorcycles with lightweight pressed-aluminum beam frames from which the motors hung, and unique pivoting forks that used a spring box near the steering head.
In 1926 he founded Neander Motorfahrzeug GmbH in Düren and went into production, using a pressed-steel frame that was cadmium plated instead of his aluminum prototypes.
These novel frames housed a variety of motors, from small 122cc Villiers two-strokes to 350cc and 500cc single-cylinder engines by Küchen, to large v-twins by J.A.P.
The Neander motorcycle had futuristic styling, with a curved, padded leather seat behind an egg-shaped fuel tank, and very clean lines.
With excellent handling from the pressed-steel frame, Neanders won quite a few races, and have a very comfortable, stable, and predictable ride.
