Summary

This mount has been designed to conceal an airtag under a bike saddle, between the metal rods usually found under it.

Why another bike saddle mount for airtags

I know, there are numerous designs out already, exactly like this one, but all of them are too large for my own bike saddle (a Xiaomi QiCycle). So I decided to make a new one that can be easily changed to fit any saddle size.

Also, it's designed to be lightweight (only 2 bolt & screws are needed to secure it) and to let the airtag's top cover be free to not muffle its ringing.

Harware needed

2x M2x8mm
2x M2 bolts
1 Apple Airtag (obviously)

Changes

2022/08/23 - Removed the sort of “lock” on the holder, as it was indeed too frail and didn't help much to secure the mount. As it stands after 2 weeks of use, the screws are largely enough to keep both parts together.

How I Designed This

How to modify this design for your needs

You'll need an Onshape account to do so (it's free). Once created, just click on the link below and copy the document.

You can change all the parameters if you want, but i'd rather stick to only change mount_spread and mount_diameter. The first one defines the space in mm between the 2 metal rods under your saddle, and the second the diameter in mm of each rod.

For new onshape users, here's a quick video below showing you how to modify those.
