I was about to write about what I saw as far as pedaling but he covered it, lol. I am not a strong peddler either, just big batteries and time. Did 95 last wed and then 75 yesterday , each trip used 2 batteries, different speeds and different terrain. on the 95 miles trip i did 60 on 1 battery and came back the same way but faster and got 35 miles on the 2nd both depleted. It is about how much effort your motor makes, either your input or the terrain which give different speeds, the worst is trying to go fast up hill
