Frame size
I am looking for a bike for my wife. We are kind of new to biking. We started riding last summer on some Wal-Mart bikes and just about totally wore them out in one summer so we are looking to upgrade. I am hoping to find an eighties model schwinn or something similar, but I am confused about frame size. My wife is about 5' 6". I was wondering if someone could give an idea about what size of frame she would need.
