Just bought the lectric xp 3.0 w/ extended battery. It will not go faster than 17.5 ish throttle only. Even on the 100 setting. Cust serv. said to drain battery and recharge. What a Pain. I drained (rode 15 miles) until no power to wheel and error code on screen. Still 17.5 tops. Now what? Back to customer service. later tonight Just went 18.5 after I changed setting from 100 to 32. I managed 26 on pas 5. I cant believe I have a bike that goes 18.5. I changed back to 100 from 32. Still 18.5 throttle only. Tires at 34 psi. My xp 2.0 went 21.5 on setting 100 with throttle only. The voltage is full or nearly at 54 volts. Does anyone have an answer ? Thanks.
