How To Track Your Bike With An AirTag
A hidden tracker won't stop a theft, but it is the single thing most likely to get the bike back afterward — police recover bikes from live Find My locations regularly. It only works if it's genuinely hidden, mounted so it doesn't rattle, and kept charged. Here's how to set one up properly, on any bike.
Pick a tracker
If you or anyone in your household uses an iPhone, an Apple AirTag is the strongest choice in Australia — it piggybacks on the Find My network, so millions of other people's iPhones anonymously relay its location whenever one passes near it. On Android, a Tile or a Chipolo works the same way on a smaller network. One tracker is enough; two, hidden in different places, means a thief who finds the first still hasn't found the second.
Choose a genuinely hidden spot
A thief who spots a tracker will throw it away within minutes, so the obvious clip under the saddle is close to useless. Better places: dropped down inside the seat tube (on a strong string taped under the seatpost so you can pull it back out), inside a hollow handlebar end under the bar plug, behind a bottle-cage boss, or sealed inside a saddlebag or a bar bag you always leave on the bike. On an e-bike, the battery cavity or a bag over the rear rack both work.
Mount it so it can't rattle
A loose AirTag knocking around inside a frame is annoying on every ride and audibly advertises itself to anyone handling the bike. Wrap it in a turn or two of foam tape or a purpose-made silicone sleeve, or use a seatpost mount designed to hold an AirTag. It should sit snug and silent.
Register it in Find My or the Tile app
For an AirTag: open Find My → Items → Add Item → Add AirTag, hold it near your unlocked iPhone, and name it something like "Bike". For a Tile: open the Tile app → Add a Tile and follow the pairing steps. This links the tracker to your account so only you can see its location.
Test the range, and set the alerts the way you want
Walk 20 or 30 metres away and confirm the bike's location updates. On iPhone, decide deliberately about "Notify When Left Behind" — handy for a bag, but for a bike you park on purpose every day it just nags you, so many people turn it off for the bike tag specifically.
Keep the battery fresh
An AirTag's CR2032 coin cell lasts roughly a year; a Tile's varies by model. Put a yearly reminder in your calendar to swap or recharge it. A flat tracker is worse than no tracker, because you believe you're covered when you aren't.
Know how to share the location if the bike is stolen
If your bike is taken, open Find My → select the bike tag → Share Item Location to generate a link, and give that link to police — it lets them follow the bike's live location without needing your phone. Add the same link to your bike on SpokeID (Edit Bike → Tracker Share Link) ahead of time, and it's automatically attached to your police report if you ever mark the bike stolen. Don't go after the bike yourself — hand the location to the police.
