This excellent video below helps illustrate the main points about how to lock
your bike:
Tip 1 – Choose your location
Always make sure you don’t attach your bike to something that can easily be
broken, moved or lifted off. Spend that extra 5 minutes when you are out and
about to find a more secure object and your bike safety will be ensured.
Well lit area with CCTV cameras around are the most ideal
It is preferable to choose an area where other people are around and are
frequently walking past. Never leave it in an isolated place
Lock it near to other bikes – there is a decreased chance of thieves
picking your bike as there will be easier targets around
Tip 2 – Use your lock effectively
Lock the frame, front and back wheel to the object you have secured your
bike to
Make sure the D-lock is tightly fastened so it is not hanging loose
between the bike and the object you have locked it to
Face the D-lock (U-lock) keyway facing down so that they cannot spray
liquid into it
Don’t place the lock too near the ground as then it is easier to
leverage them for attack
