I made a topic awhile ago about trying to find a free mtb on craigslist, to use to learn.

Well, I can't find a single free mtb on craigslist.

I was thinking about maybe just buying one of the really cheap ones.

Any of these worth it?

Old gt backwoods bike- 50$

Old raleigh mtb- 30$

Old rockhopper- 75$, but I was thinking I could offer less like 25-30 dollars
