Weight is very relevant going uphill. Where I ride we routinely do rides that climb thousands of feet. We have one rider who only weighs 130lbs and he has never used more than half his battery on any of our rides. For those rides, weight correlates closely with battery use. Flat or downhill then weight is not important. You are right that height is irrelevantI'm just in from a 20mile off road ride with my 18yr old. I rode my Eeb simply because it was closest to the door and ready to go so I rode the entire route with the bike switched off.
I'm a good bit heavier than you and under 6ft. Not that I've any idea why our weights or heights are relevant.
