Jean Fuchs
Fahrbau Jean Fuchs und Co. Erkelenz
Located at Hindenburgstraße 30, Erkelenz (now Kölner Straße), in addition to building motorcycles Fuchs sold petrol and ran a driving school. He was well-known as a sporting cyclist and motorist in the 1920s.
Fuchs engines of 114cc were first advertised in the latter half of 1922. Villiers engines were fitted to some models, and it is likely that engines from Snob and Struco were also utilised.
Motorcycle production appears to have ceased around late 1925 , but the business continued until perhaps 1935.
A Fuchs motorcycle with a 169cc two-stroke engine has been displayed at Rheinisches Feuerwehrmuseum in Erkelenz-Lövenich.

Joka
Manufactured by Joseph Kanzler GmbH, Motorradbau, Großenhain / Saxony, in 1925.
Type IV used an Esbe two-stroke engine, and later that year models with 130cc and 175cc engines from Adma appeared. Another model was built using a Villiers 172cc two-stroke and a Jardine gearbox.
The trade press announced that the Joka would have more sophisticated engines from Küchen and Kühne for the 1926 season, but there is no evidence that production continued into that year.

Jonus
Marketed by Joseph Nussbaum & Co. GmbH, Köln, 1924-1925.
It is believed that the Jonus machines were built by Alfred Wiseman of Birmingham, quite possibly obtained from NV Snob Motor-Cycles of Schiedam, Netherlands.
Jonus Models:
A snippet on German racing during that period states that "Carl Jurisch ...two days before the start of the first Deutschlandfahrt in 1924... the gearbox of his Bekamo broke. He quickly procured a 350cc Jonus from England… and won a gold medal in the difficult winter race."
In 1927 Joseph Nussbaum & Co was a Rudge-Whitworth dealer, and in 1929 was selling Matchless and James motorcycles.

Jüngerkes
Josef Jüngerkes opened a bicycle shop in Viersen around 1909 and by 1913 was also retailing motorcycles.
He began racing in 1923, riding Villiers-powered Fuchs motorcycles. He had 13 wins on the Fuchs in 1924. In 1925 he was competing using his own brand name, Jüngerkes, and several other men also rode these.
Most were equipped with 150 cc engines, and in 1926 a Villiers 175 model appeared. That year he began racing a DKW, and there is no further reference to his own brand. In 1929 the firm began retailing Dixi products (possibly Cyklon) along with P&M motorcycles and Villiers engines. Postwar, the firm serviced Ilo machines.
