Paul Wackwitz of Crefeld (now Krefeld, near Dusseldorf) built 106cc four-stroke bicycle attachment engines supplied separately or complete with bicycle frames. His business was established in 1904 or possibly earlier, and was listed at several addresses in Crefeld over the years.
The Wackwitz appeared in local racing results in 1923, and the brand was offered by a nearby dealer in 1924. The company experience financial difficulties in 1925, and little more was heard of it before it was dissolved in 1929.
