    A smaller sprocket on the back wheel or higher voltage but the control unit might not like it or same sprocket bigger back wheel. Remember it makes it harder to take off and might kill the motor but I wood try anything

    Will 36 volts fry the controller?

    And how much speed do you think I'll gain going from a 55 tooth sprocket to a 44 tooth?

    It is about 1 mph per tooth reduction. If things are not optimal maybe 0.75 mph gained.
