• STRONG & DURABLE
  This bicycle U-lock is crafted from 14mm high-strength alloy steel with a zinc alloy lock cylinder and soft silicone coating. It is significantly stronger than traditional cable locks—even 12-ton hydraulic shears cannot cut through this U-lock.
• DOUBLE PROTECTION
  ROCKBROS U-locks feature a double-bolt locking mechanism. This dual-opening design provides an extra layer of security, making it twice as difficult for thieves to break.
• SILICONE PROTECTIVE COVER
  The exterior of the lock is wrapped in soft-touch silicone, which provides a comfortable grip and prevents the lock from scratching your bike’s paint during use.
• INCLUDES 2 KEYS
  The keys feature complex serpentine grooves that are extremely difficult to replicate. Combined with the double-locking method, this system ensures maximum safety and reliability.
• WIDE APPLICATION
  Ideal for bicycles, motorcycles, gates, fences, and more. Get the ultimate security and protect your ride with this heavy-duty U-lock.
