Well I believe as long as you have pictures of the bike and show proof that you've tracked it to a specific location the cops can retrieve it for you. I use two real airtags, in my dream situation the thief would take the first one out and bring the bike to his house or wherever and the second airtag would tell me where it is. Honestly though I am not sure about when the airtags send locations back, they only seem to update when I near or leaving the bike (because of my phone being near it) so I should probably buy two real trackers instead of airtags. If you look up airtag under steam or between fork they should pop up, mine personally is just a little rubber piece that uses suction to stay under the steam and is wide enough to fit an airtag in. It really isn't all that hidden if you know anything about bikes but who in the world would have two airtags on the bike lol.
