This may or not help; today's MTB ride, per my friend's Strava set up, was 12 miles, 3200' of ascent, (about 8 mph average). He @ 150 pounds used 20% of his Bulls (Brose motor) 600 a-h battery. Me @ 180 pounds riding a BBS02 and 52V, 6 a-h battery used 25-30% of the capacity. Theoretically he could travel 50-60 miles, me 30+. We pedaled moderately most of the time and without the motors on flat or downhill areas, but as vigorously as possible on the climbs.
