hi, folks, great site, lots of info here, appreciate that.
I grew up on a Rupp Roadster 2,in the mid seventies. lost track of that one...bummer.
I have a grandson and I want to build his first bike.
I thought of another Rupp, I'd still like to find one I could bring back to life. I found this instead:
I think it's a Rupp knock off, not home made, though. Being a mechanical engineer, I can tell.
My question is, anybody ever seen one of these?
The big distinguishing difference is the only way I can see to adjust the secondary chain is a slot at the rear wheel pivot, or a chain tensioner that is no longer there.
From the manufactured design I think it is American made.
Thanks for the help in this
