I’ve also learned that I can’t stand battery operated motion sensors!
Have you found any plug-in motion sensors that you use instead? It looks like they are generally much more expensive than the battery powered ones, which doesn’t make any sense to me.
Try dyna beads or any other brand dynamic balance beads. You pour them into the tire through the valve stem and that’s it. When the wheel is turning they naturally move around to the light spot and balance the wheel. I’ve used them in many bikes and they work great until you get to track day speed (120+ mph).
