    Is there a method that will magnetize one spoke so the speedo transmitter can see it. I've thrown sensors off the wheel so often there's got to be a better way.laff

    Nothing permanent unless you remove the spoke first. I magnetize my screwdrivers with this.

    OR
    If the spoke is placed into the center of a coil of wire, and then a large amount of DIRECT CURRENT is sent through the wire, the item can be magnetized. The orientation of its poles will match the orientation of the field generated by the coil.

    Somehow I doubt you could get the magnetic force on a single spoke strong enough...

    When I used a bike computer on my motorcycle which had non-spoke rims, I used JB Weld to hold the magnet on. Never threw the magnet over the course of thousands of miles and hitting 100+ MPH on the track. Maybe the same would work for you?

    A little dab of silicone adhesive works great and you won't have a lump of hard, difficult to remove goop on your spokes.
    Sorry, I hate JB Weld.

    Just a dab of blue lock tight. My spoke magnets have done fine for me. Once a blue moon might lean the bike somewhere or something? Never caught it in the act? To see it got re-clocked somehow? Very very rare for me tho.

    Most of the time just put them on right from the packaging. Have seen that coating on bike bolts like these before tho from the factory. Like with brake and rotor hardware.

    I put a new worksman wheel on front and didn't want to lose my magnet. I used JB Weld neatly---I don't expect it to be an issue--ever---dance1
