Used mountain bike for $75. Ride it for a year. Sell it for $75.
Where I live, people put them on the curb. I have in the past. Not worth the trubble to do craigslist for $50.
Edit: I would amend this to say you need to have bike fixit skills to make this work, but if the bike shifts/brakes on a test ride, it's probably OK
