So I noticed something kind of weird on my middrive yesterday. I never usually check the wattage consumption readings but this time I did. At 18 mph (I know slow, but the bike trails here allow for 15 only and I don't want too much attention) my bike in third gear uses just under 350 watts. I decided to shift into fourth just to see what happens. I expected my consumption to go up trying to maintain the same 18 mph, but surprisingly it actually dropped to just over 200. This is kind of weird because I thought electric motors were supposed to be more efficient the higher they rev. Of course, as soon as I hit any minor incline I had to downshift or else the consumption would shoot up, but this was on flat ground and I kept it steady at 18. At third gear at this speed, I'm getting 17wh/mile, so in fourth I guess it's possible to get better? Any reason why I'm using less power in fourth gear you think?
