A crowd-network tag and a SIM tracker fail in completely different places · review
A holder that hides a tag inside the fork steerer of a mountain bike, fitting internal diameters of 32 to 38 mm (1.26 to 1.50 in) and doubling as a plug against dirt.
Our conclusion The best-hidden option here, if your fork takes it. Measure the steerer's internal diameter first.
egmatec’s plug puts the tag somewhere nobody looks, and solves a second small problem while it is there.
Injection molded, made in Germany. Simple, secure and hidden mounting of an AirTag or SmartTag2 in a mountain bike fork. A single version for steerer internal diameters of 32 to 38 mm (1.26 to 1.50 in) — if the tag fits into the opening, the holder fits. Usable as a plug to prevent dirt collecting in the fork steerer.
A thief checking a bike for a tracker looks under the saddle, in the bottle cage and at the bar ends. The inside of the fork steerer is not a place anyone thinks about, and it needs the bike partly dismantled to reach.
Your fork has to have an accessible open steerer of the right internal size. Many mountain bike forks do; many road forks do not, and some are filled by a star nut or expander plug that is doing structural work. Check before ordering, and do not remove anything holding the headset in preload.
A genuinely useful secondary function. An open steerer collects grit and water; a plug keeps both out.
Like every crowd-network tag, it has no GPS and no SIM. It reports when another phone passes. In a city that works; on an empty road it does not.
A listing is not an offer: the reference exists on these stores, availability changes daily.

8.4 × 3.9 × 1.1 cm (3.3 × 1.5 × 0.4 in) · ABS · bottle boss mount · screws and key supplied
A concealed AirTag holder that mounts under or in place of a bottle cage, in ABS, supplied with two 25 mm (0.98 in) M5 screws and an Allen key.

An under-saddle AirTag holder in ABS, stated to fit almost any saddle across mountain, e-, road and city bikes, and compatible with both AirTag generations.

A working 85 dB bell with an AirTag concealed inside it, for 31.8 mm (1.25 in) handlebars only, supplied with the tools to fit it.
