Does anyone remember the old schwinn folding bikes from the early 1970's? I think it was called a runabout, and had a high seat post, high handlebars and came in green. I am trying to locate one.

The obvious eBay, craigslist. You may want to post "bike wanted" ads.

Is this it?

I vaguely remember that Schwinn model. It was intended for the older retired crowd. It was somewhat of a flop if memory serves. I modeled my Brompton after this and other 60s and 70s bikes that I owned or still own. I think that bike is superior over the older ones.
