If you don’t want your AirTag or its mount to be visible when attached to your bike, an under-saddle mount such as the Ninja bikeTag Saddle mount is a great option. The Slottr is made from a highly durable plastic which is designed to last and prevent your AirTag from rattling thanks to its well-designed internal compartment. Maybe. The concept is pleasingly simple, and if it works, it’s a stroke of elegant genius. But, of course, it has to work. That means friction is the only thing securing it. Could it pop out when you land a drop or rattle your way over choppy trails? There’s only one way to know for sure. Still, a low-cost threshold might justify trying it out — especially depending on how much you spent on your bike. Without beating around the bush, of all the AirTag mounts I tested for this review, the AirBell is my favourite and will go unnoticed by even the most observant and experienced thieves.

The one downside of this mount is that it’s slightly more fiddly to attach due to the mounting position, but once it’s in place, you’ll have no issues. Out of all the mounts I tested for this review, I found the Woo Holder to be the easiest to use, taking under a minute to get it set up. This AirTag bicycle holder mounts to the water bottle position on your bike. If bottle cages already occupy yours, it’s no problem. If you don’t have long nails, It can be fiddly to open the Slottr, which doesn’t have a notch in the side for easy access like the Woo Mount. As stated, if a few small changes were made to the Slottr it would be greatly improved, but as it stands, I’d recommend the AirBell or Woo Holder ahead of this.A 1.5mm Allen key is supplied, which tightens a singular M2 screw, securing the Maco onto your bike’s seatpost.

Bicycle theft is depressingly common, with 77,148 bikes reported stolen in England and Wales during 2022/23. The Slottr is a fairly generic mount that performed well during our testing and is the most affordable mount found in this review. Like other bottle-mounted AirTag holders, the Slottr can fit beneath a bottle cage, making it harder for a thief to spot.Will it fit on your bicycle? Not all AirTags are a perfect fit. Make sure the one you select is not moving around or unable to properly attach to your bicycle. A Torx Pin screw would have been preferable to a Phillips screw for securing the AirBell, as it would make it harder to remove if a thief became aware of the AirTag’s presence. In addition, the Slottr is supplied with standard M4 (4mm) hex screws, meaning it could easily be removed if your bike was stolen. Well-designed, durable and discoverable at an average of 56ft. Not as far as the Slottr Tag holder, but a cleaner appearance, better design and more user friendly. My seatpost has a diameter of 27.2mm, but I found that the Maco didn’t tighten enough to secure it firmly in place, so I added a small strip of rubber padding underneath the Maco’s spacer, securing it in place.

It seems like the idea for the Stealth Tag was hiding in plain sight. Now, the Stealth Tag itself will be doing the same thing.

A Quick Audit: Is the Stealth Tag Any Good?

Also, when riding busy Urban Streets, you’ll often need to be heard to be seen, which is where the AirBell comes in handy.

Your AirTag sits inside the aluminium shell, and is secure inside by two hex screws, which do make the mounting process slightly longer.

Is it easy for thieves to remove? Some mounts come with tamper-resistant Torx screws making it impossible for thieves to open or remove them. Functioning as a traditional bike bell, hitting 85dB, the AirBell sits proudly on your handlebars, perfectly concealing your AirTag underneath and alerting others of your presence on the road.
