Ive been riding brakeless for the past 2 months and I live in a town such as yours, hills and flat terrain. Im pretty good at keeping a slow pace down hills but I know if an emergency situation arised I would have to dodge it because I wouldnt be able to stop, which could be good or bad. My new bike is coming pretty soon and I opted to keep a front brake on. Not to use but just to have in case of a true emergency stop. I popped my chain going downhill, and brakeless the other day. Lets just say it scared some sense into me.
