I was interested in the terrain aspect. I have a rechargeable electric lawn mower, and if, due to rain, or laziness, I mow the lawn when it is really long, that really taxes the battery. I was wondering if people live in hilly or mountainous terrain and if hills (fighting gravity) really suck the life out of the battery.
That's pretty incredible, at that city speed you were averaging just 90wHr per km, or about 150 whr per mile, much less than the 250 - 280 people were getting, and I was expecting over 300 whr per mile. 90 whr per km is exceptional.
Hope you were near home when the warning light came on, lol. Nice job!
