Heavy-Duty 5mm Steel Bar Lock – Built for Ultimate Security! Protect your ride with our robust 5mm steel bar lock, designed to withstand even the toughest attempts at theft. Made from heat-treated, special hardened steel, this lock resists 12T hydraulic cutters, thumping, sawing, and drilling. The plastic coating ensures your bike’s paintwork remains scratch-free, while the bars are linked with hardened steel rivets that can withstand up to 1.5 tons of pulling force. The advanced lock cylinder features a slim key (0.3-0.6mm), making it resistant to technical picking, while the anti-drilling cap and manual keyhole cover add an extra layer of security. It’s easy to remove forwards, making it perfect for small-framed bikes. To prevent any issues with lost keys, be sure to record the key number or keep a spare key at home. Strong, secure, and designed for ultimate peace of mind—get yours today!
