i'm looking for a bike for my girlfriend who is 5'1". I found a 38-cm Schwinn Sprint Road Bike 10-Speed Lugged Steel on craigslist for $125. I may or may not convert it to a fixie. Not too familiar with the Schwinn Sprint. Is this a good quality schwinn or a cheapo one? How much should this bike be worth? Thanks for any help.
