Ultra 410 Mini U-Lock

A U-lock is a sturdy bicycle lock shaped like the letter "U." It secures your bike frame and wheel to a fixed object, making it extremely difficult for thieves to steal your bike. Its solid metal construction provides high resistance against cutting and twisting attacks, ensuring your bike remains safe when parked.

Hardened steel is treated to enhance its hardness and strength, making it more resistant to bending, cutting, and other forms of attack. A lock made from 12mm temper hardened steel provides superior durability and security, giving you peace of mind that your bike is well-protected against theft.

A patented double-layer key design features two levels of security, making it significantly harder for thieves to pick the lock. This unique mechanism is legally protected, ensuring that only the original manufacturer can produce this specific key type, which adds an extra layer of security to your bike lock.

The synthetic coating on a U-lock serves as a protective layer that prevents scratches and dings on your bike frame when the lock is used. This coating helps maintain your bike's appearance and protects it from damage, ensuring that your investment stays looking new for longer.

A rattle-free shackle is designed to fit snugly in its mount, preventing noise while you ride. This feature is particularly beneficial for cyclists who prefer a quiet ride, as it reduces distractions from the lock, allowing you to focus on your journey without annoying rattling sounds.

To determine the right size U-lock for your bike, consider the dimensions of your bike frame and the objects you plan to secure it to. A good U-lock should be long enough to fit around your bike frame and wheel while also securing it to a fixed object. Measure the distance between the frame and the object to ensure a proper fit, and choose a U-lock that meets those requirements.
