The frames themselves aren't 32" -- Wal-Mart is perpetuating the horrible and misleading ractice of using wheel sizes to denote the scale of the frame -- 24" bikes for kids, 26" bikes for bigger kids and adults, 29ers for larger adults, etc. My guess is that since the 36" wheel size is somewhat impractical, they're trying to find out if there's a market for something in between 29" and 36".
