Got 27 miles from my 504 battery yesterday, about 3800 elevation was quite a bit of climbing on dusty Shale, and roots could get more as Trail felt a bit too much tbh.
I find on flat fire roads when ya pushing on, And over the limit the gearing poor, just end up spinning,this is the time I like to save battery power but still got the legs to push, Deadmeat gave some good advice on this on the BLEvo post whilst mocking my grammar, ?guy seems to no his stuff.
