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.

If her body proportions are average, she's probably going to fit a 53cm (21") road, 16/17" mountain, or 18/19" hybrid frame with a shortish stem.

You really need to measure any frame you are considering. A size 52 in one brand could be close to a 56 in another brand. Some manufacturers measure from center of bottom bracket to top of seat tube (c-t), others measure from center bottom bracket to the intersection of the center of the top tube and the center of the seat tube (c-c). One of the most important measurements is the length of the top tube. This is measured along the axis of the top tube from the axis of the seat tube to the axis of the head tube.
Many bicycles have sloping top tubes. Top tube length on these is known as "effective top tube length" and is measured as if the top tube was level with the ground, starting with the intersection of the axis of the top tube and the axis of the head tube. Many manufacturers have geometry charts for their bikes available on-line.
I use my wife's sewing tape measure which is perfect for bicycles. It's metric on one side and English on the other, and it's cheap.
