• Tracking method
  • Apple AirTag works via Bluetooth and Apple’s “Find My” (crowd-GPS) system.
  • A GPS tracker uses satellite signals and cellular/mobile data to send real-time location updates.
• Range & accuracy
  • AirTag is good for short distances (up to ~30 m) via Bluetooth; longer-range tracking depends on nearby iPhone users.
  • GPS trackers can locate moving objects over long distances reliably and continuously.
• Hidden installation / mounting
  • AirTags must be hidden carefully on the bike (to avoid detection/removal).
  • GPS trackers can (and should) be mounted inconspicuously (inside frames, under bottle cages, etc.).
• Pros & cons
  AirTag advantages: small, cheap, easy to use.
  AirTag disadvantages: limited range, not suited for real-time tracking, and its anti-stalking alerts may reveal its presence to thieves.
  GPS tracker advantages: accurate, real-time location, better theft-recovery potential.
  GPS tracker disadvantages: more expensive, higher power / battery demands.
• Which is better for protecting a bike?
  • AirTags are fine for finding lost items but are not reliable for recovering a stolen bike.
  • If your goal is theft protection and recovery, a proper GPS tracker is the better choice.
  • The article cites 3BO’s GPS tracker as an example of a solution that can provide real-time tracking and hidden installation.
• Conclusion
  An Apple AirTag is handy for everyday objects, but not suitable as a theft-prevention device for bikes. To protect and recover a stolen bike, you need a genuine GPS tracker (such as what 3BO offers) rather than a Bluetooth tag.

If you’re looking for a relatively inexpensive and easy-to-use way to track your bike, an AirTag is a good option. However, keep in mind that AirTags rely on other Apple devices to be nearby in order to provide an accurate location, so they may not work as well in rural areas. If you need a more reliable tracking solution, or if you want additional features, such as geofence alerts and crash detection, a GPS tracker is a better option.

Ultimately, the best way to choose between an AirTag and a GPS tracker is to consider your individual needs and budget.
