I ride a variety of terrain with varied wind speeds. I'm about 200 pounds. Decidedly average fitness. Use Giant's Syncdrive which is a PW, and Syncdrive Pro which is a PW-X.
On flat terrain with stop-go traffic on Eco and some cargo, I'd say about 100 km with about 30% left in the tank from 90+%. The assist cuts out at 15.5 mph, so I never go faster than that with assist. It's very efficient and goes quite far. Not too fast, though.
Using the US-spec PWX, assist is palpably stronger on Eco as well, and I go up to 20 mph, but on what is supposedly also a 500 Wh battery, the range is shorter at maybe 70km from 90% to about 20%.
Range on Sport on the PW goes down to as short as 30 miles (48 km) with rolling terrain or moderately steep climbs. Off-road, I can kill the battery in 28 km on really tough terrain with very challenging climbs.
