Yes, alarm bike locks are effective in deterring thieves. When a thief attempts to steal a bike secured with an alarm lock, the loud sound of the alarm startles them and draws attention. This decreases the chances of the thief successfully stealing the bike and may discourage them from attempting it again in the future.
2. What do bike thieves use?
Bike thieves commonly use angle grinders to cut through locks and steal bikes. These powerful tools can easily cut through even the strongest locks. To protect your bike, it is recommended to invest in a lock made of hardened steel or titanium, as they offer greater resistance to cutting and are more difficult for thieves to bypass.
