I must digress fellows. Some say the distance they are placed, closer to the axle or closer to the rim does not matter. I say it must. I say this because my motor cannot do over 20 MPH. I notice top speed closer to the rim is 19 and closer to the axle is 21 mph. If the positioning along the spoke is not the cause I do not know what is. Try it for yourself. Both times the distance from sensor to magnet was measure by a nickel. A nickel is exactly the right width.

It'sJustMe, yeah, I read the book. I have been using it for months.. I just wanted to re-adjust it better than guessing.
