Preventing Cycle Theft

In Gloucestershire bicycles are one of the most targeted items by thieves.

Don’t give a thief a free ride …. Register your bike (for details, please see our poster )

There are a number of free on line registration services that are quick and easy to use. If your bike is stolen and found by the police then a quick check will confirm you as the owner.

Security mark your bike

There are a number of options for security marking your bike.

A UV marking system is an effective way of both marking your valuables and sending out a strong message to thieves.

A colourless liquid solution is simply dabbed onto the uneven surfaces of your valuables. It can be used to code all sorts of items such as cycles as well as the various cycle components, jewellery, ornaments, electrical items and even your motor vehicle. Each bottle contains a unique chemical ‘code’ which is registered to you – conclusively proving ownership.  It cannot be easily seen by the naked eye and is almost impossible to remove.  The liquid glows under ultraviolet light making it easy for the police to detect.

Keep a note of the serial number 

All bike frames are given a serial number. This is normally located underneath the bike and should be written down or photographed and kept somewhere safe.

Involved in Bike Racing Events?

Thieves will specifically target these events as they know that competitors will probably own an expensive mountain bike often costing thousands of pounds. They are probably targeting the expensive components on your bike rather than the bike itself so marking the frame is probably not sufficient.

There are some precautions that you should take including:

  • Don’t advertise details of your races on social networking sites.
  • Be aware of suspicious vehicles following you home after events. If you believe you are being followed dial 999 and try and drive to an area where there are lots of people around.
  • Don’t leave your bike unattended or unlocked.
  • If you sign a petition of any kind in a known cycling area put down your telephone number rather than your address.
  • Insure your bike.
  • Make sure your bike is secure at home.

For a free home security assessment please ring 101 and ask to speak to your local officers.

Think about bike security.

Places to avoid:

How to lock you bikeDark Alleys

Even if your bike is locked, a thief will have an ideal opportunity to break through your lock.

Butterfly Racks

Avoid parking which only allows you to secure your front wheel to the stand. Even if you don’t have quick release wheels, it’s very easy for a thief to detach your wheel and make off with the rest of your bike.

Short Posts or even tall posts that a lock can fit over the top of. 

Your bike will be lifted over the top. Even if there is a sign at the top that your lock can’t fit around, bear in mind that a very determined thief could unscrew the sign and lift your bike over, so it’s not a good idea to leave your bike locked to sign post overnight.
