Hidden AirTag Bike Mount - Customizable

Introducing our smart and discreet AirTag holder, specially designed for bikes. This mount fits seamlessly under the frame's steering wheel bar, providing a secure spot for your Apple AirTag.

Simply insert your AirTag into the holder and push it into place under the frame. It may require some force, but small holes are made for easy removal using your nail or a flat screwdriver.

UPDATE 1/2/2026: 

• The file has been updated with support for customizing it right here in MakerWorld! No need to download and open it up in Fusion anymore. Sizing can be easily adjusted right here from the browser

• Thanks to @ExtractMan feedback, I've also added cut notches which allows more flexibility when inserting the device (and the other way around). 

  

Original description:

Originally designed for the Gazelle Paris C7, this holder may also work with other models.

Additionally, the Fusion 360 file allows for easy customization. Pay attention to the "OuterInnerCylinderDiameter" parameter (don't ask me why I gave it that name) , which specifies the diameter of the bar hole, and the "OuterCylinderHeight" parameter, which specifies how deep the mount should be pushed in before hitting something. If the filling depth is lower than the thickness of the AirTag, the Fusion file will create a thicker ring around the surface while still ensuring a snug fit without gaps (See the images below).

But I would generally recommend that you only focus on the cylinder diameter if possible.

I've also developed a version featuring small holes, enhancing the sound transmission of your AirTag when you need to locate it. In the Fusion File you can roll the History Marker one step ahead to see it.
