Know this…

  • Check your insurance documents – often insurance companies will set out the ways in which your bike needs to be protected in order for them to pay out.
  • Look for ‘Thatcham Approved’ or ‘Sold Secure’ ratings when choosing security products.
  • When chaining up your bike, keep slack out of the chain to keep it (and the lock) off the ground – this makes it a lot harder for thieves to attack it.
  • Parking your bike in a public place can help, but don’t rely on harassed shoppers to take much notice of a bike alarm, or even a balaclava-wearing hoodlum wheeling a bike into onto a trailer.
  • A disk-lock is a handy deterrent, but a thief can always pop the wheel on a skateboard to make it easier to roll your bike into a van.
  • Always use the best possible security you can, but a massive chain will only secure your bike if you actually use it.
