5mm Hardened Steel Bar Lock – Maximum Protection for Your Bike! Designed for ultimate security, our 5mm bar lock is built from heat-treated special hardened steel, making it resistant to 12T hydraulic cutters, thumping, sawing, and drilling. The plastic coating ensures your bike’s paintwork stays safe from scratches, while the bars are linked with hardened steel rivets that can withstand up to 1.5 tons of pulling force. Featuring advanced lock cylinder technology, the slim key (0.3-0.6mm) is highly resistant to technical picking, with an added anti-drilling cap and manually operated keyhole cover for extra security. The lock is easy to remove forward, making it ideal for small-framed bikes. To avoid any issues with lost keys, we recommend recording the key number or keeping a spare key at home. Strong, reliable, and easy to use—secure your bike with confidence!
