How to hide an Apple AirTag on your bicycle

How to hide an Apple AirTag on your bicycle

Apple's AirTags are an economical tracker system that works with your mobile phone or computer to help you find lost or misplaced items, like car keys or a purse. Cyclists have noticed that AirTags can be used to help track and recover stolen bicycles, and have begun hiding them on their bikes.

At just $29 each or 4 for $100, AirTags are economical enough that you can install one on every bike you own. Let's take a look at some of the various ways to mount or hide an AirTag on your bike for theft prevention and recovery.

Mount an AirTag under a water bottle cage

If your bike has the standard two-bolt braze-on for water bottle cages, you can mount an AirTag right underneath the bottle cage. Although it's visible, it's also bolted to the bike, which might slow down a thief who tries to remove it.

A few enterprising riders have started designing 3D printed or molded plastic mounts for this purpose, such as this model from Etsy.

Hide an AirTag inside the steerer tube of a suspension fork

Looking for a less visible way to mount an AirTag? How about hiding one in the bottom of the hollow interior of a suspension fork steerer tube?

Stealth Tag™ from spencer3dprints is designed for just that. This 3D-printed gadget comes in various sizes to suit suspension fork models from Fox, and Rockshox. Unfortunately, this design won't work on forks where the bottom of the steerer tube is closed off (like ENVE cyclocross forks) which rules out this option for most rigid carbon models.

Hide an AirTag under a Specialized saddle

The same seller as the Stealth Tag for suspension forks also sells a version specific to Specialized Power and Romin saddles. Super clean look, since it uses the bolts built into the saddle for mounting. 

Don't have a megabucks saddle? On Etsy, you can find a version designed to work on other saddle models. The mounting isn't quite as clean as the Specialized version, but it should work on just about any make/model of saddle.

Seatpost-mounted reflector and AirTag holder

Reflectors are a common sight on bicycles, so a thief might overlook an AirTag hidden inside one. This clever seatpost-mounted combo reflector, also from Etsy, is inexpensive and stealthy. Serious cyclists probably use a flashing taillight, not a reflector, but it might be OK for more casual use, or you can run the reflector and flashing light side-by-side.

Stash an AirTag inside a saddle bag

If you prefer a low-tech, low-cost way of carrying an AirTag on your bike, simply drop one inside a saddle-mounted bag. A saddle bag can quickly be removed and discarded, but if the thief doesn't check inside, the AirTag might be missed.

Hide an AirTag inside your tubeless MTB or gravel tire

Muc-Off has created an AirTag holder attached to the portion of a tubeless valve that sits inside your tire! Now that's stealthy. Due to the width of the AirTag, you'll need a wide, higher air volume tire to accomodate the shape, which rules out narrower road and cyclocross tires. Cool idea nonetheless.
