How to make your bicycle safe?

A number of crimes(罪行) are against bicycles. About 150,000 bicycles are stolen every year and most of them are never found. You can prevent this from happening by following a few careful steps.

Basic Security

Never leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lamp posts or trees. Take off smaller parts and carry them with you, for example lights and saddles (车座).

Locks

There are various types of locks. Buy one that has been tested against attack. Ask for a suggestion from a bike shop owner.

Marking

The security marking of your bike can act as a prevention of being stolen, which can also help the police find your bicycle. Your postcode and your house or flat number should be included and clearly recorded. This will provide a simple way to recognize your bicycle.

Registration (注册)

There are many companies that will offer the security marking to your bicycle. They will then store your registration number and personal details in their computer database(数据库). If your bicycle is found, it will be easy to contact you.

Attention

Keep a record of the bicycle by yourself: its production place, model and registration number. You can even take a photograph of it. This will prove the bicycle belongs to you.
