Hm the 14.4 Zero I'm on did 100 miles yesterday with 15% remaining. Admittedly I rode like a nun for half of the journey (55mph max), but the first half was normal 60-65mph in between towns and villages.

And like I have said before, my 2018 Zero S with Power Tank (with a
claimed 16.6 kWh) once went 150 miles on a single charge, which included two 1500-foot elevation uphill and downhill slogs at 35 mph and then a 55 mph run against a headwind up the coast highway to home (which gobbled up the last 50% SOC).
Most of my Zero riding now is back and forth to my daughter's home located 38 miles away. About 20 miles is usually around 65 mph, including a couple of 500-foot elevation rises, with the other 18 miles consisting of stop-and-go, being ridden at a average of 40 mph, between stops. When I am riding against the wind on a cold morning (40 degrees F) I will arrive at her home with the display showing as little as 62% SOC. But on a morning with no wind and a temperature of 55 degrees F, I will see 72% SOC. On the return trip, typically with a moderate to stiff side wind and the temperature around 70 degrees F, I will usually arrive home also with 72% SOC, but that ride usually includes more aggressive throttle action and more stop-and-go. Between my weight, and a full top box and seat pack of stuff, the additional weight, over and above the bike's 452 pounds, is typically about 180 pounds.
The only odd thing I really notice lately, which may or may not have anything to do with a slightly degraded battery, is that the first 2% SOC is going away noticeably faster than it used to do.
