hi everyone, here's the problem. i was riding at about 26 MPH and suddently the buzzer went off on me. At the same time i felt i lost thrust! i stop for a second or two, the buzzer stop and i was able to keep on going at a lower speed. i just change the impeller not long ago so i don't think is the impeller. anyone know what might have happened. thanks for all your help. Daniel
