i wanna be discrete. thanks for the note tho.Do a google search for AirTag mounting bracket. Cycliq has a neat mounting bracket for use on a bike. But Amazon has a lot of brackets, one of which is integrated into water bottle cage.
yes yes, that's it. i forgot about that hole.They have sticky pads that are designed to go on the inside of suitcases:
Put one of those on the back of the seat (nice smooth surface to stick to) so the tag is fitting inside one of the frame holes.
