I have an ebay 1000w motor, running 18s lipo with the hua tong and my top speed is 78kmh, had a tail wind though. 0-20kph is ok, 20-55kph is very quick, 55-65 still pretty good. I can hit 70 kph most of the time even up some light hills. 60kph is very easy to reach. ive now upped the voltage to 20s and its a bit nicer again. i run 8ah packs, milage can be up to 50ks or as little as 13 if i hammer it lol. Going for 24s next but i need to tame the throttle as it is jerky as hell. I ditched the thumb controller for a lcd twist throttle with speed display. I set up cruise, it works very well, if i dont use it, the slightest bumps give me a nice torque surge. I cant stand whist accelerating, it forces me to sit. Does no pop wheelies unless i pop it slightly and then it will mono quick!, also up steep hills it wants to mono.
