Hi all, I'm new to the forums and biking in general. Im looking at 2 bikes and looking for advice on which to choose. I am about 5'5 and havent ridden a bike in years but am in good shape and very active. Im looking for a multipurpose mountain bike. I will be using it for flat terrain as well as offroad trails. While I wont be entering any races, my buddies and I are pretty competitive. Also would a 15 or 17' frame be better? Any help would be appreciated.
