If you haven't ridden in a long time, and are basically starting again at 52, I suggest you start with a bottom of the line bike from someplace like Academy and make sure you like riding and will stick with it before you invest a lot of money. It is not as easy as you remembered, and it would be a shame to spend a lot of money only to find you don't want to do it. Then, if you do like it and stick with it you can upgrade.
