I ride my MB on the road all the time. I'm not in any shape to go off roading anymore and the MB is all I have. My DH has put smoother tires on my bike to help the resistance since I don't ride much off road, but they are still also big enough that I can ride off road some without worrying about getting an instant flat. My avg speed right now is anywhere from 10 to 11, but I ride a lot of hills out here where I live and dont' expect a lot of speed. I am more interested in getting fit and losing weight anyway though.
