Welcome. At 5' 0", unfortunately it will be very tough to find many stores that have bikes you'll be able to test. I'm also 5'0". I was lucky to be able to test 2 bikes when I was looking. One was a Trek Lexa and the other a Specalized Dolce. The thing about this is I live on the NC coast, the Lexa I tested I was 5 hours away in Charlotte, the Dolce was over 2 hours away in Raleigh. (Happened to be in each city for other reasons so was lucky to be able test each one). What I learned was that I need a men's bike because I felt to cramped on the WSD bikes. I have shorter legs with a longer toros/arms. Definitely find a shop that is going to work with you and is concerned about what you need. Another brand to check out is Felt. Felt's WSD line is the WZ line. I bought an F series bike (which is a men's line that there is no WSD version of). I love the bike and it fits me wonderfully.
