B5 U-Lock Details
Product Description
Engineered from a 40CR hardened steel body and finished with a heat-treated, electroplated coating, this lock delivers exceptional strength and weather resistance without compromising on style.
Wrapped in a smooth, anti-scratch silicone coating, the B5 keeps your bike protected from cosmetic damage while offering a secure, clean aesthetic. The 12-ton cutting resistance ensures it stands up to serious force, while the zinc alloy lock cylinder offers precision and durability for smooth, reliable locking.
Heat-Treated & Electroplated
Our lock's steel body undergoes a precision heat-treatment process that enhances its structural integrity—boosting resistance to cutting, bending, and impact forces.
Following this, the steel receives an electroplated coating - a high-performance finish that bonds directly to the steel surface. This adds a critical layer of corrosion resistance, shielding the lock from rust, wear, and harsh environmental exposure.
Zinc-Alloy Lock Cylinder
Built for durability and smooth performance, this corrosion-resistant zinc-alloy cylinder offers strong tamper protection in a compact, lightweight design - perfect for secure, long-lasting use.
Words from our customers
It does exactly what I want: locks quick, feels secure, and hasn’t jammed or failed on me once. Great for everyday riding.
I’ve used this for uni every day and it hasn’t let me down. The coating has stopped it from scratching the frame so far which I really like.
Been using this U-lock for about 3 weeks now. I lock up my bike in the city most days and haven’t had any issues. Feels solid and reliable.
Took this lock on a 3-week road trip with the bikes mounted on the van. Left them locked up overnight a few times and never had a problem. Solid build.
