My riding weight is around 91 kg. Same bike as you. Without riding your trails, I am only guessing, but
I struggle to get around a 70km (44 miles) 'double Pass' circuit with nowhere near 6600' of climbing. Tyres on advice from LBS = 25 front, 28 rear. Mostly unsealed roads, and mostly 40% power assist ( power level 2/5) when climbing..If you are climbing steepish technical stuff, on a 500 Wh battery, I think 25 miles may be all you can expect.
Incidentally, the manuals that come with the bike claim up to 110 kilometres on a full battery. To get that, I would have to be riding on a smooth tarsealed highway, slightly downhill, with a howling gale up my backside.
