Our conclusion Clever, and the best-selling holder here. Measure the bar at the mounting point first — 31.8 mm (1.25 in) is exact, not approximate.
The AirBell hides a tag inside a component the bike needs anyway, which is a genuinely good idea.
What the manufacturer publishes
Compatibility with Apple AirTag first and second generation, not included, mounted discreetly inside the bell. Fitting for 31.8 mm (1.25 in) handlebars only, described as typical of road bikes, mountain bikes and many e-bikes. Tested quality, 85 dB loudness. Tools included. Location through Apple’s Find My network via any nearby iOS device.
Why a bell is a good hiding place
It is a normal component. Nothing about the bike looks modified, and there is no extra object bolted on to attract attention. In many countries a bell is required equipment anyway, so it is a purchase that was going to happen.
The 31.8 mm (1.25 in) constraint
Take this literally. A handlebar is frequently 31.8 mm (1.25 in) at the stem clamp and 22.2 mm (0.87 in) at the grips, where a bell usually sits. Measure at the point where the bell will actually mount, and if that is 22.2 mm (0.87 in) this is the wrong variant.
What the tag does
The same as every crowd-network tag: no GPS, no SIM, reports when another phone passes. A recovery aid in populated areas.

The questions riders ask
What bar diameter does it need?
AIRBELL states 31.8 mm (1.25 in) only — typical of road bikes, mountain bikes and many e-bikes at the clamp area. Note that many flat bars are 22.2 mm (0.87 in) at the grip and 31.8 mm (1.25 in) at the stem, so measure where the bell will actually sit.
Is it loud enough to be useful?
The manufacturer states 85 dB, which is a working bell rather than a token one.

Fork steerer 32–38 mm (1.26 to 1.50 in) internal · injection molded in Germany · doubles as a plug
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.
Best for: Mountain bikes with an open fork steerer, where the most invisible hiding place is the point.
Under-saddle mount · ABS · AirTag 1 and 2 · universal saddle fit
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.
Best for: Any bike, because it needs no measurement — the fallback when the fork and bottle cage options do not fit.
