Alarm 440 U-Lock

Hardened steel is treated to enhance its hardness and strength, making it significantly more resistant to cutting, breaking, or bending. This means that a U-lock made from hardened steel provides superior security for your bike, deterring potential thieves and ensuring your bike remains safe.

A U-lock is shaped like the letter "U" and consists of a solid bar that locks into a crossbar, creating a secure loop. You can use this loop to lock your bike to a stationary object, such as a bike rack. The design of the U-lock makes it difficult for thieves to tamper with or break, providing a reliable way to protect your bike.

A 100 dB alarm is extremely loud and can be heard from a considerable distance, making it an effective deterrent against theft. This high sound level alerts you and those nearby if someone attempts to tamper with your lock, increasing the chances of catching a thief in the act.

Our U-lock features high-quality lock cylinders designed to resist lock-picking techniques. This means that even skilled thieves will find it challenging to open the lock without the original key, providing an added layer of security for your bicycle.

The U-lock uses CR2 batteries, which are cylindrical and commonly found in small electronic devices. To maintain the alarm system, it's important to check the battery level regularly and replace them as needed. This ensures that the alarm remains functional and ready to protect your bike.

Yes, our U-lock is designed to withstand various weather conditions. The hardened steel construction is resistant to rust and corrosion, ensuring that it remains effective and reliable, whether it's raining, snowing, or sunny. Just make sure to periodically check the lock for any signs of wear or damage.
