The Cambridge Cycling Campaign provides information about keeping your bicycle safe.

Register your bicycle’s frame number

If you have had your bicycle stolen and think you know where it is, the police will need evidence that it's yours. The best evidence is the frame number – find yours and write it down somewhere safe.

Find the frame number on:

• Seat mast
• Rear stay bars
• Upper cross bar
• Rear forks
• Lower cross bar
• Hanger bracket near sprocket

You can register your bike with Immobilise, a free register of ownership details for personal or business possessions.

Together with the police's National Mobile Property Register and CheckMEND websites, Immobilise an effective tool in helping to reduce crime and recovering personal property.

Bicycle registration on Immobilise only takes a couple of minutes. All you need is your bike's make, model, identifying number code(s) and a few photographs.

Your bicycle might have been removed, not stolen

If you leave your bike for a significant length of time, particularly if it isn’t locked to a cycle rack, we might consider it to be abandoned and remove it. We might also remove it if it’s causing an obstruction.
