Go to the Goodwill/ Salvation Army store and see if anyone has donated bicycles. I live a traveling lifestyle and find some amazing bargains on bikes in those places as well as in pawn shops. Bikes take up a lot of floor space so they tend to sell them below their worth. Try looking at those places that are closest to the richest neighborhoods you can find, as the people donating them probably didn't get their stuff at "Wally World "to begin with.
