My goodness, it looks like something from 1969, but it sure is clean. Those spoke reflectors are a bit suspicious; I don't think they had any such thing at that time. But maybe they were added later.

I can't tell you much about that bike, though. Roadmaster is a name that's been around a while. These days they are foreign made, bargain basement bikes. If that's authentic, then it might be American made and perhaps of similar quality to the Huffys and Murrays of the time. Which isn't exactly terrible, just not high end.

Pretty neat find, in any case.
