What the numbers mean

Bicycle theft is badly under-recorded. An estimated 40 to 60% of UK bike thefts are reported to police, so official crime statistics capture only part of the picture. A frame-number check works from a different angle: it cross-references a bike against a stolen-bike registry and rider-filed theft reports, so it can surface a stolen bike whether or not the theft ever reached a recorded-crime figure.

A flagged result means the frame or serial number matches a record on a UK stolen-bike database. A clear result means no match was found, which is reassuring but not a cast-iron guarantee, because not every theft is reported or registered. The safest approach is to combine a database check with the basics: proof of purchase, a look at the frame-number area for tampering, and meeting in a public place.

Frequently asked questions

Is there a UK police stolen bike database?

There is no single public police database you can search yourself. UK police forces and national stolen-bike registers share records, and you check a bike by running its frame or serial number against those UK stolen-bike databases. Cyclesite's free checker does this in seconds and needs no account.

How can I check if a bike is stolen for free?

Find the bike's frame number, usually stamped under the bottom bracket where the pedals meet the frame, then run it through a free check against a stolen-bike registry and rider-filed theft reports. If the bike has been reported stolen and logged, the check flags it. Always see the bike and its frame number in person before buying.

How common is bike theft in the UK?

Bicycle theft is badly under-recorded. An estimated 40 to 60% of UK bike thefts are reported to police, so official crime figures understate the true scale. A frame-number check works from a different angle and can surface a stolen bike whether or not the theft ever reached a recorded-crime figure.

What does it mean if a bike is flagged as stolen?

A flagged result means the frame or serial number matches a record on a UK stolen-bike database. A clear result means no match was found, which is reassuring but not a cast-iron guarantee, because not every theft is reported or registered. Combine a database check with proof of purchase and a look at the frame-number area for tampering.

What should I do if my bike is stolen?

Report it to the police as soon as you can and ask for a crime reference number, which your insurer will need. Then tell your insurer and mark the bike as stolen on the national registers, so any future check against a stolen-bike registry and rider-filed theft reports flags it. Acting quickly gives the best chance of recovery.

UK bike theft hotspots

Reported bicycle thefts within about 1 mile of each city centre in June 2026, from police open data. This counts city-centre reports and is not adjusted for population, so compact, dense cycling cities can rank alongside much larger ones.
