So, now my motor is sounding strained at slow speeds. I've taken it apart and cleaned it according to how everyone says to do it. Its still sparking around the carbon brushes and making a buzzing sound at low speed and it seems to be not getting enough electricity from the pedal until its pushed almost all the way down. Is this a pedal problem. The motor is really quiet with the belt off of it.
Also, how easy is your wheel supposed to turn when the motor is attached to it via the belt? Mine seems awefully slugglish. I've oiled everything I've possible could. I'm starting to think this machine wants to be loud, but I want it to be quiet as a mouse.
