That would be a cool urban neighborhood bike for knocking around coffee shops and festivals. As a bike, though, it's just a far inferior product to the Via or the Public. I ride an old bike much like that one and a new aluminum hybrid. Although the new one is a low end bike, it's just way better. Industry standards have improved in certain ways that make a decent bike much more ridable today.

A new steel bike would be even better, but that happens to be exactly what you're looking at.

For a first or only bike, for you, I would say never mind the cool vintage Schwinn. Get one later as a knockabout cruiser. Definitely not as part of a fitness routine unless you have no choice.
