As a precaution against theft, all junior members of the University who have bicycles in Cambridge are required to have them marked with a number. Numbers are issued by the Colleges and should be clearly displayed, preferably on the rear mudguard.
It is not advisable to leave a bicycle unlocked, and it is recommend that you take a note of the frame number. If your bicycle is stolen you are advised to report the loss to the Police Station without delay. It is, of course illegal and dangerous to ride a bicycle after dark without lights, to cycle on pedestrian pavements, and to ignore traffic lights.
