(Mass Appeal) – Biking is not only a great form of exercise, but it is also a wonderful way for families and friends to spend time together, especially with all of our local rail trails. But, before you head out you need to make sure your bike is in good working order which is why we’ve invited Sean Condon, Owner of Speed and Sprocket Cycle Works, a mobile bike shop, here to Mass Appeal to show us some basic bike maintenance.
