I want to thank everyone on this thread that provided useful information on Airtags and Tiles.

I was unaware of those devices and I think I am going to get one of the Tile options this coming spring. (Nobody will be stealing a bike from me during winter here in the north country.)

I was not interested in paying a subscription for a cell connection for a tracker. Thus, the Tile option interests me. I do not use an Apple phone, thus the Airtag is not an option.

I was interested in more info. A couple other articles I read are listed below, the second one is paywall but it might open for you, not sure if the first is paywall or not:

Hmmmmmm. Not sure where the best place to hide something like that on a bike is.
