The Matrix Saddle Tagger is a simple and straightforward holder for an Apple AirTag and is a smart addition to any bicycle. It is made from our lightweight, extremely durable composite matrix material and is neatly and discreetly attached under the bike seat by clamping it onto the rails. The installation is easy and secure with a waterproof, IP67-certified twist-lock design, held in place with an included TR25 safety bolt that also clamps it firmly to the saddle rails. Once installed, the hidden tagger can be used with Apple's "Find My" network to locate a lost or stolen bike. The tagger has also been tested and verified for the use of ultra-wideband signals. Apple AirTag not included.
