Peugeot, Bianchi, Raleigh, Free Spirit, Nishiki, Gitane, and others...
If the Free Spirit bike is complete and usable, it is a good bike. Think of it as basic transportation.
I have a couple of really nice 12-speed Free Spirit road bikes, including an Aero. As Department Store bikes go, they are not bad. Better than Huffy !!
In some areas, like the big Canadian city nearest me (Toronto) where any vintage road bike that is made in France or Italy disappears as soon as you walk away from it, no matter how securely chained & locked, a Sears Free Spirit has the advantage of at least still being there when you return for it.
I have found those models to be a step up from the average department store bike and nice as a casual neighborhood or recreational rider. Worth the time for a little clean up and new set of tires - IMHO.
