Tracedwn Cage — Hidden Bike Tracker Water Bottle Cage, No Subscription
A fully functional gloss-black bottle cage with the tracker built into the base mount — invisible from every angle. Your bike just looks like a bike.

Why hidden wins
Security through invisibility.
A tracker only works if no one finds it. Tracedwn hides inside the parts your bike already has — so nothing looks like tech, and nothing gets removed.

FAQ
Questions, answered.
Do I need a subscription?
No. Tracedwn uses the Apple Find My network — no SIM, no app, no monthly fees, ever.
Which phones does it work with?
Any iPhone with Apple Find My. Add the device once and locate your bike straight from the Find My app.
How long does the battery last?
About 12 months. Install it once and you won't think about it again for a year.
Will a thief find the tracker?
Unlikely. Nothing on the outside says "tracker" — it looks like an ordinary reflector or bottle cage, so it doesn't get removed.
