What to Do if Your Bike Is Stolen
By Samuel Pfeiffer, Founder of SafeOrStolen · Updated September 24, 2026
Short answer: Find your bike's serial number, file a police report, and log it on SafeOrStolen so anyone who checks that serial sees it was reported stolen. Then watch local marketplaces and send any match to police rather than meeting the seller.
Where to find your bike serial number
The frame serial is usually stamped under the bottom bracket. If the bike is gone, look for it in your records.
- Your receipt, warranty card, or the shop that sold you the bike.
- An existing bike registration or SafeOrStolen record.
- Photos of the bike, especially of the underside of the frame.
- E-bikes: the manufacturer app or account may list the frame, battery, or motor numbers.
Steps to take now
Work through these in order. Speed matters for tracking, blocking, and insurance, and the identifier is what police, carriers, registries, and insurers ask for.
1. File a police report
Cost: Free
Report the theft with the serial number, make, model, color, size, photos, and any distinctive parts.
What it tells you: You get a report number registries and insurers can reference.
2. Log the item on SafeOrStolen
Cost: Free with an account
Add the item, its identifier, and your police report number at /report-stolen. SafeOrStolen checks its own stolen-item reports whenever someone runs that identifier.
What it tells you: Anyone who checks that identifier on SafeOrStolen sees that it was reported stolen. It does not notify police, carriers, insurers, or other registries.
3. Check your insurance
Cost: Depends on your policy
Homeowners, renters, or dedicated bike insurance may cover theft. Have the police report number and receipt ready.
What it tells you: What is covered and what proof the insurer needs.
Mistakes to avoid
- Meeting a seller who has your bike or trying to take it back yourself.
- Posting your serial number publicly without also reporting it to police and registries.
- Waiting to report; resale listings can appear quickly.
Keep records and follow up
- Keep a single file with the police report number, officer or agency name, identifier, photos, receipt, and every call reference number.
- Write down dates and times of each call, claim, and report.
- Watch marketplaces for your item and send any listing to the investigating officer instead of contacting the seller.
- Update your report and registries if the item is recovered, so it is no longer shown as stolen.
Do not try to recover an item yourself or confront anyone who has it. Give the information to police. Call emergency services only if someone is in immediate danger.
Log it on SafeOrStolen. Add the item and its identifier to SafeOrStolen's stolen-item reports, so anyone who checks that identifier on SafeOrStolen sees it was reported stolen. This does not replace a police report.
Report a stolen itemWhere SafeOrStolen fits
SafeOrStolen is a stolen-item verification hub for buyers and sellers covering phones, vehicles, license plates, serial-numbered electronics and power tools, firearms, and bicycles. For theft victims, the useful part is the report: once your item is logged, a buyer who checks its identifier on SafeOrStolen sees it was reported stolen. SafeOrStolen does not file police reports or contact carriers or insurers for you.
SafeOrStolen checks its own stolen-item reports, public web results, and AI notes. Guns are also checked against police theft and loss reports from 34 states plus live Ohio records, bikes against a national stolen-bicycle registry, and paid phone checks search the lost and stolen phone blacklist. It does not search NCIC, DMV or insurance records; those are separate checks described in this guide.
Buyers can save the result with their other due-diligence records. After a clean check, sellers can share a Proof of Clean Purchase: a permanent, timestamped verification record. It is not a title, guarantee of ownership, or legal document.
