Apple AirTag (with hidden bike mount)

An AirTag is not a GPS tracker — it relies on nearby iPhones to report its location through the Find My network — but in a populated area like the Dallas suburbs that network is dense enough to locate a stolen e-bike surprisingly often. The trick is hiding it: under the saddle in a purpose-made mount, inside a bell-shaped mount, in a reflector housing or under a bottle cage. Thieves know to look, so pick a mount that is not obvious. Battery life is about a year on a coin cell. Android users should look at Tile or a Google Find My Device tracker instead.

Best for: iPhone owners · Urban and suburban parking · Pairing with a good lock
