Record the cycle's frame number (this is usually written under the cycle near the pedals) and keep other details that can help positively identify a cycle in case of theft. A photo showing these details is perfect.
Cycles are easily stolen, so remember to carry a lock and use it. If the cycle isn't parked in a safe place, some people prefer to remove the front wheel from the cycle and lock it together with the back wheel and frame, to the cycle stand or whatever you are locking your cycle to. All items that aren't fixed to the cycle or are easily removed should be taken with you (eg bike pump, helmet).
