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.

The Invoxia Bike Tracker is a real GPS and cellular tracker disguised as a rear reflector that bolts to the seatpost. It alerts your phone on movement, reports location on its own network rather than relying on passing phones, and works for iPhone and Android. The catch is a subscription after the included period, and battery life measured in weeks rather than a year, since it has to transmit. For owners of expensive e-bikes who park outside regularly, a true GPS tracker paired with a strong lock is the most effective recovery setup short of insurance.
Best for: High-value e-bikes parked outdoors · Android users who cannot use AirTag · Riders who want motion alerts

This is the lock to buy when the bike costs more than the rent. The Fahgettaboudit Mini uses an 18 mm hardened steel shackle with a double-deadbolt crossbar, which puts it in the small group of locks that shrug off bolt cutters and force attackers to use a grinder and time. The mini shackle is deliberately small so there is little room to fit a jack or pry bar. The trade-off is that small opening: you will not lock both frame and wheel to a fat pole with it, and it is heavy enough that many owners leave it at the office rack and carry something lighter for quick stops.

The Knog Scout does two jobs: it is a motion alarm that screams when the bike is moved, and it is an Apple Find My device so you can locate it like an AirTag. It bolts to the bottle-cage bosses with security screws and is controlled from the Knog app. The alarm is loud enough to make a thief reconsider a quick grab, and it arms and disarms automatically as your phone comes and goes. It is iPhone-only for the Find My function. Rechargeable via USB-C. It works best as a layer on top of a real lock, not a substitute.
Best for: iPhone users who want alarm plus location · Bikes parked briefly outside shops · Tamper deterrence
