    A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found.

You can prevent this happening by following a few careful steps.

    Basic Security

    Do not leave you bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure (栓牢)

it to lampposts (灯柱) or trees. Take off smaller parts and take them with you, such as lights and saddles (车

座).

    Locks

    Get a good lock. There are many different types in the shops. Buy one that has been tested against attack.

Ask for a recommendation from a bike stop.

     Marking

     Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It

should be clearly written and include you postcode and your house or flat number. This will provide a simple

way to identify your bicycle.

     Registration

     There are a number of companies who will security mark your bicycle for you. They will then put your

registration number and personal details on their computer database. Then if your bicycle is found it will be

easy to contact you.

     Finally keep a record of the bicycle yourself: its make, model and registration number. You can even take

a photograph of it. This will prove the bicycle belongs to you.
