I think it’s due to using unlimited hub motors specifically, those somehow are ridiculously efficient. On my unlimited hubs (on this build) 12S4P P42A pack on them gives me about 100 km / 60 mi of cruising at around 15 mph (if I am trying to be efficient and not use excess throttle). Good luck finding unlimited hubs though, they aren’t sold anymore and you can’t even buy sleeves for them.
