You're looking at quite a size difference between the first two and the second two. If you are big enough for a 58, I think the chrome one is the coolest looking. If you have to go smaller, I would say the white one. An issue I can think of with these older bikes is that 27 inch tires and tubes may not be as readily available?? I haven't really shopped for them though, so I don't know.
Haha, the only thing I hate about that guy is that the bars on all his bikes are facing way upward. If you get one, adjust it so the lower section of the bars is parallel to the ground please.
