(can you see the AirTag above? It's hidden under the water bottle.)
6 months in: How's the bike AirTag holder?
Physically, how is the AirTag bike mount doing?
I haven't had to touch it it at all, but visually it looks great. I'm confident that there's been no water ingress due to the weatherproofing gasket. I forget that it's there most of the time. I also don't really notice it because it's hidden under the water bottle cage.
When do I use the AirTag with my bike?
I find myself using the AirTag when I have left my bike parked somewhere for a while and just want to make sure the bike is still where I left it. For example, if I'm dining somewhere, sometimes I'll check the FindMy app sometime during the meal just to make sure. But other than that, thankfully, I haven't needed to use it much. (Three of our bike-riding-friends have had bikes stolen recently and they still can't ride with us now. So maybe that makes me a little more concerned about bicycle theft than most?)
What's the next bike AirTag holder milestone?
Apple cites "more than a year" of battery life, so at some point I expect to get a low battery warning at some point in time. If your AirTag battery is low, you will be able to see the "Low Battery" notification in the FindMy app.
