I went to Thick Bikes today to get a simple bike to ride to work. I was worried about going in because bike stores can be intimidating if you're not _really_ into bikes.
I drove up and there was ample parking in the lot in front of the shop (Score! How often does that happen on the south side?) I stepped out of my car and was greeted by Dan (I think that was his name) who was friendly and helpful and not even a little condescending. He knew what I needed and recommended a very reasonably priced bike. He helped me pick out a rack for the back of the bike and assured me I could install it myself (though the shop would do it for $8). All in all I was very happy with the service, and the bike seems great (though I haven't taken it on a serious ride yet).
They also appeared to have some higher end bikes, road bikes and lots and lots of accessories and parts. Also, the owner of the shop (who is a transplant from Brooklyn) does custom work etc.
Welcome to Pittsburgh, Thick Bikes!
