Model

Your Brompton is easy to fold. Unfortunately, that also makes it easy to steal.

This small mount hides an Apple AirTag underneath your saddle — out of sight, secured with anti-theft screws, and weighing just 5.4g. If your bike goes missing, you'll know exactly where it is.

How it works

The mount screws directly into the threaded hole already built into the underside of the original Brompton saddle. No drilling, no modifications. Drop your AirTag in, secure the cover with the included screws, and you're done. The folding bike logo faces outward — that's the only visible sign anything is there.

Important: this mount only works with the original Brompton saddle, which has a threaded hole underneath. Check the underside of your saddle before ordering — if there's no threaded hole, this won't fit.

Key features

  • Anti-theft screws — can't be removed without the right tool
  • 3D printed nylon — lightweight (5.4g) and durable
  • Includes everything you need — mount, 4 screws, 3 nuts, 2 tools, plus a spare set of screws and nuts
  • No modifications needed — uses the existing threaded hole in the Brompton saddle
