Update to show how variable it can get
Yesterday I set off with a full charge - first time out for 3 weeks due to weather and illness (not Covid!!) so I was feeling a bit unfit
Hence I put the assist up to Tour from Eco
I also changed my route to avoid a bit that gets very muddy in winter - so that adds in "The Big Hill



" - long steep drag for a mile and a half
Overall I did 24 miles and dropped from 5 bars to 3 bars
Today I went out again and did 17 miles - back in Eco mode and no hills to speak of
I ran out of electrons 100 yards from home - can I judge it or what!!!!
so - battery had been sitting around for 3 weeks - so possibly drained a bit but not much
a bigish hill
total 41 miles
In summer have done things like that and got back with 2 bars left. I always seem to have a shorter range in winter when the battery gets cold
Of course, everything else is also cold and there is a lot more mud and stuff around so oily bit won't lubricate as well so friction could be higher and chains and stuff could have more gritty stuff which also doesn;t help
But in my mind the temperature makes a difference of at least 10% at times
