We’ve said before that creating layers of security around your bike are key to helping prevent it from being stolen. A disclock will stop a thief from snapping the steering lock and pushing it away, either on foot or with an assist from an accomplice on another bike.
A chain and lock, particularly if secured to an immovable object, will prevent this as well as several thieves picking the bike up and loading it into a van.
Something else thieves dislike intensely is noise; they prefer to ply their trade in the dark and in silence so anything that creates a lot of noise as soon as they begin to attack a bike is a very good thing – it draws attention which is something they hate and hopefully, will make them give up and move on.

There are several forms of bike alarm; ones that are fitted to the bike and wired in permanently so they cannot be immobilised, standalone alarms that are taped or fitted to the bike with a strap, others that forms part of another security device such as a padlock or disclock and the siren sounds when they are tampered with.
An alarm to create attention if the bike is tampered with is a useful addition in your armoury of security devices – just make sure you choose (and set-up) one that is stable and doesn’t suffer false alarms and you’ll be good to go.
