Heavy-Duty Alloy Steel U-Lock with Dual-Sided Security & Silicone Protection

  • HEAVY-DUTY ANTI-THEFT SECURITY
    The ROCKBROS bike U-lock is built from high-quality steel and strengthened through vacuum heat treatment, making it extremely difficult to cut with common tools. With a max diameter of 22mm and a weight of 1.76 lbs (0.8 kg), this lock provides solid, reliable protection for daily use.
  • DURABLE, HIGH-SECURITY LOCK CORE
    The precision-engineered lock core uses a unique key design to resist lock-picking and technical opening. A protective dust cover and durable cylinder extend the lock’s service life, keeping it working smoothly over time.
  • EASY-TO-CARRY MOUNTING BRACKET
    Sized at 8.27 × 4.33 inches (21 × 11 cm), the U-lock comes with a mounting bracket that attaches directly to your bike frame. It keeps the lock secure while riding and makes it convenient to take with you on every trip.
  • STURDY, BIKE-FRIENDLY DESIGN
    The lock is wrapped in a thick silicone coating to prevent scratches and withstand daily wear. Suitable for road bikes, mountain bikes, e-bikes, commuter bikes, and even for securing gates or fences.

Customer photo review of Heavy-Duty Anti-Cut Bike U-Lock

It's exactly what I wanted very strong and the mount is perfect I'm really satisfied with the lock i recommend ☆☆☆☆☆

Adrian M. 5/5 Verified

Lightweight and mounts perfectly on my segway zt3. Inexpensive and will keep someone from easily grabbing my scooter when I step away for a quick purchase inside the store or coffee shop.

Jamie H. 5/5 Verified

I needed a good bike lock that works for two bikes when on the bike rack on my van. This lock serves the purpose well and I like how it does not damage the surface of the bikes.
