3D Cabin AirTag Bike Mount Holder Bracket Attachment (Bolts Included) for Standard Bottle Cage 64mm Bicycle Cycling Accessory Black

Shipping time is respectable, as I got mine within a week even though it came from UK (to US). It's not the most sleek-looking gizmo you will see and craftsmanship is only OK but it does what it's supposed to: form a bike-mountable protective shell around your Apple AirTag for a very good price. The mounting holes line up perfectly with my road bike (Specialized) so no problem there.The only thing I don't like is that it's a bit bulky, the two half shells together measure almost exactly half an inch thick (AirTag is about 0.3" thick), which is the reason two mounting bolts are included.Still, it's one of the first to the market and a well-thought-out product. I give it 4 stars and hope there are future improvements.Update: see photo. Bolt holes completely disintegrated after a bumpy ride through city streets. Not recommended unless you only ride on smooth tarmac.

It does work as promised, holding an AirTag securely and fairly unobtrusively. Plus the bolts are long enough to also hold my water bottle cage firmly.I do have a concern about water leakage inside it during rain or washing the bike, however. No rubber gasket or O-ring is provided. Water getting trapped inside might not be good for the AirTag. Unless the surfaces of the holder’s plastic materials self-seal sufficiently.A minor issue is that the English instructions do not appear to mention or show that the AirTag disk has a ridged side and a smooth side. The holder is built to receive the ridge when the AirTag is properly oriented.But some owners may not notice this subtlety, and miss that the holder is not closing fully, and so possibly damage the AirTag or holder when tightened. And leaving a gap for water to enter more easily. A note in the instructions saying which way the Apple logo should face would be more clear (it’s on the ridged side).

Not much too this -- but it works. Protects and hides the Airtag under the bottle cage. Even if someone knew it was there, it would take a tool and some time and effort to remove.

I added a square of inner tube on top of the airbag, and a bead of food grade silicone around the edge before closing the two halves.I plan to also run a thin bead of adhesive sealant along the seam.

Perfect fit, both onto the bike and for the AirTag

It’s a great idea but it’s not ready for prime time

The design is a little rough but this gets the job done.

I was looking for a way to discreetly hide an AirTag under the seat. The size and shape of this were perfect.

Someone’s got the right idea with these - they’re 3D printed so some budding designer somewhere has a good future ahead of them. But I would still say this is more at a prototype stage. The accuracy of the spacing of the bolt holes isn’t perfect - it means the bolts are held in tighter I guess, and harder for criminals to remove, but it was w bit of a squeeze getting it all in. The holder is also bulky as hell - sitting wuite tall above the frame, meaning that when I put my bottle cage on top, I had to get a smaller bottle in order to fit my frame. There’s a lot of material which would be removed to slim down the profile, which I may try and do when I get the opportunity. Otherwise it’s a really good solution and doesn’t block the signal compared to storing an air tag in the frame/seat tube etc. I also bought some M5 torque head security bolts for it too so that it’s harder for any thieves to get the thing off if they spotted it.If this was a little slimmer, fit the tag a bit more snug used perhaps a sliding gap for the bolts as opposed to just holes, and perhaps had a soft gasket or seal, then this would be a groundbreaking product that I can’t see anyone putting up a good argument not to buy it!

A great idea but... don't buy if you have an e-bike with batteries in the down tube. The bolts were 35mm in length and were far too long - I had to use a Dremel to cut the bolts down to length and remove the burrs. If you cannot cut the bolts down you're out of luck or need to buy others elsewhere.Feedback for the seller - offer several bolts of varying lengths.

Fits the air tag perfectly, Was a bit concerned that the relatively thick plastic would hinder the “find my” feature but upon testing it in the open air, and again in the holder, there was absolutely no discernible difference in tracking distance. Perfect for the job …

Works well and robustly made. "Does not rattle" is not quite true but easily fixed. A small amount of insulation tape on the airtag makes it just a fraction thicker and solves the issue. Product design with rubber or something similar on one of the inside surfaces would solve this. Otherwise is noticeable when riding offroad trails.

The best part are the average-quality bolts! The 3d printing is of poor quality, is unnecessarily thick with absolutely no sealing (not even a lip on one part & recess on the other). Not only that, the Airtag rattles! IMO - awful junk!
