That's actually a fairly interesting bike.
I'm using one for a commuter now.
It has a longish wheelbase, a decent geometry, room for rack & fenders
and it has the ashtabula bottom bracket (one piece crank) which I happen to quite like for utility bikes. They're easier for me to overhaul, a little narrower (keep pants out of chain, more comfortable to ride), and easier to adjust with a leatherman and a crescent wrench than a 3 piece crank.

Schwinn only had these made like this for a couple of years and then it became basically indistinguishable from the contemporary LeTour.

The only thing is the stem, which is a little bit of an odd size. However, the fork could be replaced and a standard 1" quill used.
