I assume this is without the range extender?I did a range test this morning and I’m a little surprised. I got 15.5 miles with 1600ft of climbing before the bike went dead. I’m thinking that I weigh at least 215 pounds with my gear & hydration pack. I had the power turned all the way up- 100/100. Im not gonna lie, I milked it a little. I think the reason might be that when the battery gets to 40% or so the bike starts to lose power and that last 40% goes a little further because the battery can’t discharge at a high enough rate anymore to power the bike 100%. It kills me that Specialized built the ultimate SL chassis and fitted it with a shit-burger of a battery.
What were you hoping for? Full power is always going to be a big drain, efficiency will be lower at higher power and those numbers seem pretty reasonable to me. Dial the assist back to 70% (which would be like full power on the old version) and I am guessing you would get about 20miles and 2000feet, which (for your weight) seems about right.
Add the range extender and you would get 23miles and 2400feet (at full assist).
