LEZYNELEZYNE Matrix Saddle Tagger, Stealth Bicycle Airtag Seat Mount Case, Lightweight, Durable Composite Matrix, IPX7 Waterproof, Hidden Airtag Holder for Bikes

Easy to install and should work with most saddles, but it is not that difficult for a thief to remove. Nothing wrong with the product, but if you can remove the speaker of the air tag it adds discreteness.

Works as described. Easy to use.

This is a good for an under saddle air tag mount. It is difficult to see and nice construction.I personally prefer the mounts that are even harder to see such as inside the tire; under bar tape or under a water bottle cage. The bike thieves are getting smarter but they are still dumb.Unfortunately none of those options worked on this bike so this was the best solution.Hopefully the bike isn’t stolen and if it is; hopefully the thief isn’t smart enough to remove the mount or the saddle.

This is the best airtag saddle mount I could find. It has a few simple large parts and is relatively easy to attach with a single screw. You do need to take care that the rubber gasket is in the proper place to seal. With your saddle still on your bike, you can first seal your airtag between the two disk portions with a twist lock while making sure the rubber gasket is in its proper place. Then use the screw and rail clamp to attach to your saddle rails. You will need a screwdriver that can hold the special security bit -- I have several so no issue for me but some people might not have the necessary tool to hold the bit. Depending on your saddle mount design you could have the airtag pointed backwards or with a few you could have it pointed forwards and much more hidden.With the rubber gasket I'm confident that this product is water tight.I tried a different design from another manufacturer but it was super hard to attach without flipping your bike upside down or removing your saddle entirely to install on the rails then reinstalling the saddle because the other design had lots of tiny parts that were hard to keep in place whereas the Lezyne design parts are much fewer and much larger and much easier to handle.

Just ok. It holds the AirTag securely and mounts to the bike seat frame as intended. Unfortunately, the clamping force from the single screw in the middle isn’t enough to keep the plastic tight on the bike’s seat rails. If discovered, a thief could just rip it off by hand because the plastic has enough flex that it won’t stay clamped.

Great air tag solution for bikes

Bought this for my 2022 Trek Roscoe 6 and it fit perfectly. I have tried the water bottle mounts, but this is the better solution. Very well built and water tight.

It is pretty discreet. And waterproof under the saddle. My iponly worry would be that if detected someone can snap it and get rid of it. Overall still happy with the purchase.
