Does anyone know where I can find out how pedal assist actually works. I have tried Google. My pedal assist has five magnets in a circle that pass a sensor. The magnets will only work in one direction and all the magnets are positioned the same north pole on one side and south pole on the other side. The speed that the magnets pass the sensor adjusts the speed of the motor. Logic says that if I put 5 more magnets in the same circle positioned north and south the same as the others all spaced equal that the sensor would think the wheel is going twice as fast. The opposite is true and I can't figure why?
