RMW

[Greybeard]

Ruhrtal Motorrad Werke GmbH (R.M.W.) in Neheim-Ruhr was formed in 1925 after the death of one of the partners in the original firm, Bleha.

Under the RMW marque motorcycles were built using engines produced in-house along with Siemens & Halske engines supplied by Mabeco of Berlin. By 1927 they were producing 600cc Mabeco-engined V-Twins, copies of the Indian Scout.

In 1933 another plant was opened in Sauerland which built machines under the Phönix (Phoenix) label, a marque which became very successful - so much so that the RMW models were rebadged as Phoenix. These were fitted with engines from Sturmey-Archer, Moser, MAG, Küchen and Bark of 198cc to 496cc.
