Your bike can be reached, wherever you lock it up.
A ShieldTag on your frame or scooter deck means anyone can flag you down about it — blocking a rack, an alarm going off, a bump — without your phone number ever showing.

Questions
Does this help if my bike is stolen?
ShieldTag isn’t an anti-theft or recovery device — it only relays a message when someone can see and scan the tag. Pair it with a good lock, not instead of one.
Is my phone number ever visible?
No. Messages relay through ShieldTag in both directions — your number is never shown.
What does it cost?
Anonymous messaging is free, forever. A physical tag is a one-time purchase from $6.99; paid plans add photos and more starting at $1.99/mo.
- ShieldTag is not an anti-theft or GPS tracking device — it relays a message only when a visible tag gets scanned.
