    I have searched all over, and I cannot find an explanation of what the S12S does for PAS that is different from a controller that does not simulate torque control. Does anyone know what it actually does from a technical point of view?

    Does anyone recognize this geared-hub?

I used the photo to attempt to measure the diameter of the motor, and if the wheel was 22.5 inches (26 inch with tires), then...
