Hmmmm. 7 speeds are supposedly way too many for most people, but I guess those very same "most people" fit perfectly well into just two frame sizes? My recent bike shopping experience suggests otherwise. I can hardly think of a single factor more important than fit for long term riding enjoyment. There may well be one, but it's not springing to mind. I guess if you happen to fit one of the two sizes that's great.
Anyway, this is the type of bike my wife would really love. I'll point it out to her in case she is of a mind to upgrade her cheap box store single speed cruiser at some point. Of course, at least she knows that one fits.
