The Rockbros bicycle lock is designed to provide maximum protection against theft. It's made from hardened steel and zinc alloy, ensuring high resistance to cutting, impact, and drilling. With reinforced rods measuring 22.5 mm in diameter, the lock is nearly an insurmountable obstacle for thieves.

The accessory features a double lock – both ends must be unlocked, enhancing the level of security. The clever design minimizes the risk of opening the lock with a pry bar. The keys are specially designed, making them difficult to counterfeit.

The lock is waterproof thanks to a silicone coating, which protects the steel from corrosion. A special cover protects the keyhole from water, dust, and dirt. With a holder, the lock is easily portable and practical for everyday use.
