A used folding bicycle is the most likely scenario for that to occur.

Yours is actually better than my newer model, if you want to have multiple chainrings, because yours doesn't have a brazed-on front derailleur hanger. The reason that's good is that a clamp-on front derailleur hanger offers plenty of adjustment, whereas a braze-on can't be moved and thus requires a lot more effort and expense to get a front derailleur to work.

There's one thing about the older model frame that isn't as good as the newer one. The older model doesn't have a built-in socket for a luggage truss. I didn't notice that at first because I don't use those. You can get an adapter that adds the socket, though.
