Introduction

A lot of crime is against bicycles．About 150，000 bicycles are stolen every year and most are never found．You can prevent this from happening by following a few careful steps．

Basic Security

Do not leave your bicycle in out﹣of﹣the﹣way places．Always lock your bicycle when you leave．Tie it to lampposts or trees．Take off smaller parts of the bike and take them with you．

Locks

Get a good lock．There are many different types in the shops．Buy one that has been tested against stealing．Ask for a suggestion from a bike shop．

Marking（作标记）

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 your postcode and your house or flat number．This will provide a simple way to recognize your bicycle．

Registration（登记）

There are a number of companies which will mark your bicycle for you．They will then put your registration number and personal information in their computers，such as your telephone number，email address or QQ number．Then if your bicycle is found，it will be easy to find you．

Finally

Keep a record of the bicycle yourself：its make，model，color and registration number．You can also take a photograph of it．This will show that the bicycle belongs to you．
