I track my Brompton TLine by embedding an AirTag in the Frame Plug

在金属管内部，无线信号应该被屏蔽不少。

thanks for the tire lever trick ... how easy would removing the battery?

It is pretty easy to take the battery out. Press down on the polished stainless steel battery cover of your AirTag and rotate counterclockwise until the cover stops rotating.
