Let's assume that Used means Pre-Owned. I have acquired pre-owned bicycles that were, quite literally, unused. Let's assume that used refers to how much use the bicycle has actually seen over the years.

Vintage is the bicycle's age and a general rule of thumb is the older a bicycle is the more vintage points it gets with vintage road bicycle enthusiasts. Who define classic...

Classic is a perception issue. The Volkswagon "Beetle" was not considered a classic in its day but it certainly is today. In fact, the "Beetle" or "Bug" all but created a class of car all by itself - the sub-compact.

The vintage racing bicycle, or touring bicycle or Ten Speed is classic in the sense that they are all pretty much the same in general design and appearance. Their style and appearance created a class of bicycles. Those that are the most classic are the ones that did their jobs the best, be those jobs be to win races, cover long distances or whatever. A bicycle that frequently wins big name races becomes a classic in the eyes of the collector because it was successful at its intended purpose. A bicycle that lends itself well to commuting becomes a classic because it does its job well. Hence the fame of the lowly Peugeot UO8, a really great bike to ride anywhere around town or out on the open road.

As a collector of high end or special issue Canadian vintage road bicycles, I see many of my mounts that are both classic and vintage in nature. Any person who is focused on the Italian racing bicycles might not see my bikes in the same light. Perception if the key to figuring out what is classic.

So if it is a pre-owned bicycle in like new condition and the older its vintage, the more enthusiasts will want it, then it is a example of a classic vintage bicycle. And it will cost lots of money to purchase one these days. Unless you...

Mention to every person you encounter, in the next couple of weeks, that you are looking for "an old Ten Speed bicycle, the kind with skinny tires and curved down handlebars"(important description). Betcha get one and for a paltry sum. If so, let us know how you did.

By the way, this is all just my opinion.
