Apple's AirTag is marketed for lost item tracking, but can it truly serve as an anti-theft tool when installed on high-end road bikes worth hundreds of thousands? The footage begins with the unboxing of the AirTag and its concealed installation on a bike, delving into the core principles of the Find My Bluetooth broadcast network in real-world operation. Through scenario simulations, the video tests the location update delays when a thief rides away with the bike, the anti-stalking alert mechanism, and signal dead zones when no iPhone devices are nearby. Facing these practical limitations and tracking bottlenecks, how effective can this compact locating device really be for bike theft prevention?
