That is obvious. I can't say for certain that my hills are an exact match for what he dealt with but they look and feel steep. Of course the worse the gradient becomes the more this bike struggles, but I was out for a ride last night and the final part of the circuit takes me up a very steep hill. There was a fellow slowly inching his way up the worst part in what must have been the lowest gear. Oh how I chuckled as I flicked it to full assist and went sailing past.The gradient is also important. How steep is your hill?
