Manufactured by Oberursel AG and then by Horex-Columbus. 1921-1924
Designed by Fritz Kleeman, son of the owner Freidrich, their first product was an auxiliary bicycle engine of 63cc which was in direct competition with the AMI, who took them to court and lost.
In 1923 Fritz created a 250cc OHV engine and renamed the company to Horex-Fahrzeugbau AG, marketing the new machines as Horex.

The Gnom marque was derived from the engine built by Oberursel of that name. It was built under licenced by a French company, Société Des Moteurs Gnome, which later became Gnome et Rhône.

The brothers Richard and Hugo Gruhn each had their own motorcycle firm, both based in Berlin.
1. Richard Gruhn founded his company 1906 and built motorcycles and engines until the early to mid-1930s. Gruhn engines were fitted to ABC GmbH, AMBAG and other motorcycles.
2. Hugo Gruhn operated from 1920 to around 1927 producing frames and chassis components for motorcycle manufacturers. He also marketed a lightweight motorcycle kit which included engines from Cambra, Hanfland and Diag. DKF is listed as using engines and chassis from Gruhn, so it is quite possible that both brothers supplied components for that firm.
N.B. Tragatsch says Richard's machines had "no sporting image". GTU says completely the opposite.
