I am trying to purchase a bike for my boyfriend. He would be using it for casual riding. I found a Schwinn continental (1974) 10 speed (25" frame, 34" standover) and a Ross Euro Tour 5-speed (24" frame, 33" standover)from the 1980's. Judging from the seller's photos they seem to be in similar condition. I have attached the photos that the seller provided. There was also a Ross Gran Tour 10 speed but I think it may be too small. It has a 31" standover and my boyfriend is about 6" 2. All of the bikes are priced around $100 which seems high but I do live in NYC. I would greatly appreciate any input. I don't want to get ripped off and I would like to make the best decision. Thanks.
