Would you not have to remove the tire to get to the devise? Mine drives me bonkers at times as it will 80% of the time come on and then after a short amount of time goes off and never comes back to bug me. Always comes on at the beginning of a ride as though it is cold then goes away. I learned to just look the other way when it is on then bingo, the light is off.I have read here, that the battery in the wheel tire pressure sensor, that is not meant to be replaced by the user, but can be in fact changed.
My question is: If you replace the battery, does the sensor have to be re-linked to the bike?
