Hello, everyone, I have one problem with my apn6s. I think that his maximum speed is limited. Is this possible? I can´t drive more then 45km/h, no matter if I driving downhill or uphill, bike can´t get over 45! Also, when I give him half gass, he reach 45 km/h, and whwn I raise up the gas, speed isn´t higher, but bike is louder. So he has power, but dont have speed. And if it is immportatn, I reach 3600km whittin a year and the half whit that bike.Please help, and if is possible send me a detail operating instructions how to resolve that problem. Thanks
