not to add more confusion but...
....one person who is 5'2" may ride a bike with completely different geometry than another 5'2" person. It all depends on how long your legs are, now long your torso is, and how long your arms (reach) are/is.
Find a bike shop you trust (bigger does NOT mean better!) and go get fitted for a bike. A good shop will know what fits you and will work with you to find a bike that feels right.
Still, you DO need to ride lots of bikes before you know what "right" feels like.
Good luck and don't give up! -jane
