RUPP (Swinemuende, Germany) 1928 - 1932
Two models were produced: one with a 198cc ohv-engine (own design) and a 498cc model with a (for that time) very modern "Kuechen" engine with 3-valve OHC valvetrain (see picture).
I don't know if your PC (or MAC?!) can show the german letter ä, ö, and ü.
I replace these letters in the text: Swinemünde is now Swinemuende and KÜCHEN is KUECHEN

rupp 36 spoke hub
I recently found a 36 hole conical rear motorcycle hub. marked Rupp PN33184-5 and the backing plate is marked 33186-7. i cannot find anything from the rupp minni bike folks. i was wondering if this would fit a german rupp. it was laced to a 18in Akront rim with a continental road tire on it. i can send pics if they would help. any info would be greatly appreciated.
I have done a little more research and im about sure this isnt anything the Rupp of ohio folks ever produced. Please let me know what you think.
I somehow doubt that they are from the German Rupp, either. The design is very much like that of scramblers of the late 60s and 70s. A strong clue is the fact that the brake drum and sprocket are on the same side, an unusual feature. There appears to be some writing on the brake arm - does this give any further clue, or is it just a part number?
I'll put money on it being a Maico.
