Regarding the sensor moving around:
Yeah, that's the only downside to this method. One does have to be mindful when installing and removing wheels.
I tried some super sticky industrial strength double sided tape..didn't work. That's a lot of potential force from the wheel, depending on the speed, leading to contact between the magnet and the sensor. I'm not sure if anything would stop it, aside from permanently gluing the magnet to the wheel, in which case you're gong to rip the sensor off the fork or do some other form of damage. I just don't like anything that can move that easily attached to my bike and so close to moving parts.
