Universal inner tube for mopeds with 17 inch wheels. We use these on every Puch, Motobecane, Peugeot, Honda or Sachs we build and more.
These are 17 x 2.5in tubes but fit and work great in 2.25, 2.50 and 2.75 applications. These tubes are thick too!
We buy these direct from the manufacturer so there won't be any cardboard packaging or anything.
