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.
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.
