"I was about to buy a Trek for £800. The check came back stolen. It saved me a fortune — and potentially a criminal charge for handling stolen property."

How It Works
Three steps to protect yourself from buying stolen property or being caught with a flagged bike.
-
Find the serial number
Look under the bottom bracket — the part of the frame where the pedal cranks attach. Most bikes have it stamped or etched there. It's typically 6–12 characters long.
-
Enter it above and search
Type or paste the number into the checker above. We'll search 7.5 million registered bikes and cross-reference with national police databases in seconds.
-
Act on the result
A clear result means you're good to proceed — but still ask for proof of purchase. A stolen flag means walk away immediately and report the seller to police.
What We Cross-Check
Every search queries multiple sources simultaneously for maximum accuracy.
Stolen Reports
Cross-referenced with national Police Crime Reports and BikeRegister's live stolen database.
Ownership Record
Verify that the person selling actually owns the bike through registered ownership data.
NMPR Database
The National Mobile Property Register used by all UK police forces — not just BikeRegister.
Insurance Flags
Check for outstanding insurance claims or suspicious transfer activity flagged on the asset.

"My bike was recovered because I'd registered it here. The police found it within a week — I honestly didn't expect to ever see it again."
