I would put that bike in the "wouldn't waste my time" pile. It's probably hi-ten, so it's wicked heavy and weak. The bars on that bike say "cruiser", not "ride me fast", so I'd bet the geometry is probably slack as hell (can't really tell from the photos). Add to that the cottered cranks, steel rims, and chainguard, and that bike officially qualifies as the era's low-end hybrid.
