For years I have ridden a Montague folding bike. It has served me well, but I rarely take it apart and fold it up. Once in a while I will take it into the woods as there is plenty of that here on Cape Cod. We also have a sandy soil and most dirt roads have a large sand component. That being said, here in Falmouth and the western end of the cape, one can find some rather knarly trails. I'm thinking about buying another bike, a mountain bike, that will be more durable than the Montague. However, my bike seems rather solid. What say ye?
