Bike GPS trackers
Where should a tag actually hide?
Neither of these is a tracker. Both are holders for a tag you buy separately, and the whole question is whether a thief would find it in the first minute.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
Two products in one, and the concealment is the better half: a bell on a bike is invisible because it belongs there, and in several European countries it is also a legal requirement. The constraint is real — 31.8 mm (1.25 in) bars only, which rules out the 22.2 mm (0.87 in) section where many flat-bar grips sit.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
The one that fits any bike. A universal saddle mount takes ten minutes and needs no measurement, and ABS described as weatherproof is a stated material where the AirBell publishes none. Under the saddle is the second place anyone would look, which is the trade.
No. Both are holders and the tag is a separate purchase that usually costs more than the mount. Check which phone ecosystem the tag belongs to before buying either.
They report only when a compatible phone passes within Bluetooth range. In a dense city that happens constantly; in a rural shed it may not happen at all — and the tag reports nothing rather than reporting an error.
The fork steerer, which means removing the stem to reach. The egmatec holder in this hub does that and doubles as the top cap, so nothing about the bike looks different.
31.8 mm (1.25 in) bars only · 85 dB bell · AirTag 1 and 2 · tools included
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.
Best for: Bikes that need a bell anyway, on 31.8 mm (1.25 in) bars, where one product solving two problems is the appeal.
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.
