Figures on this page are fixed. The live report at /uk-bike-theft-report updates continuously; cite an issue when the number must not move.
Methodology
- A check is one frame number submitted to the free Cyclesite stolen-bike checker during the calendar month, excluding cached re-reads and inputs that were not frame numbers.
- Bikes are counted by distinct frame number. The flag rate divides distinct flagged bikes by distinct checked bikes; it is never computed from check events.
- A flagged bike matched a stolen-bike registry or a theft report filed on Cyclesite. A clear result means no match was found in the sources consulted, which is not proof a bike was never stolen.
- The flag rate is published only when the month has at least 100 distinct bikes and at least 5 flagged; otherwise it is withheld.
- Makes come from the registry record for the frame, most often inferred from the serial number's manufacturer format, and are listed only with at least 10 bikes.
- Issues are written once and never recomputed. Corrections, if any, are published as a note, not as a changed number.
- National figures are official statistics for England and Wales, taken from the published crime tables and frozen into this issue at publication. The recorded and survey counts cover one period and the value figures a different, earlier one; both periods are stated beside the numbers. They describe the country, not Cyclesite traffic.
