The Matrix Saddle Tagger is a simple and straightforward holder for an Apple AirTag and is an intelligent 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. Installation is easy and secure with a waterproof, IP67-certified twist-lock design, held in place by a supplied TR25 security bolt that also clamps it 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.
