Sende Locks — Your Gateway to Bicycle Security Innovation.

Our U-lock series features two groundbreaking folding-style models that combine the strength of a traditional U-lock with the compact convenience of a folding lock — solving the long-standing challenges of bulky size, inconvenient portability, and troublesome mounting. These locks fold down to a fraction of the size, making them easy to carry and store on your bike frame or in your bag.

In addition, we proudly introduce our diamond-grade anti-saw U-lock — engineered with ultra-resistant materials that defy cutting tools. Sende has not only achieved a major breakthrough in cost control, making this high-level security more accessible, but has also pushed the boundaries of anti-theft performance to deliver protection that truly stands above the rest.

Built from high-hardness steel with anti-pick locking mechanisms, every U-lock in our series delivers uncompromising protection — without the bulk.

We offer a diverse range of innovative chain lock solutions designed for riders who demand both security and style. This year, we are proud to introduce our latest breakthrough — a heavy-duty chain lock featuring a lock-cylinder-free locking mechanism. No cylinder, no keyhole — just effortless one-step engagement for instant, reliable security. The design eliminates the vulnerability of traditional key cylinders while delivering unmatched convenience.

Beyond performance, our chain locks stand out with striking, contemporary designs that complement any bicycle aesthetic. From sleek finishes to distinctive shapes and vibrant color options, we've reimagined what a chain lock can look like — without compromising on safety. With high-security ratings and fresh visual appeal, Sende chain locks deliver the perfect balance of protection and personality.

Sende cable locks are designed with sustainability at their core — every component meets certified environmental standards, reflecting our commitment to protecting the planet while protecting your ride. Inside each lock head, every mechanism is precision-engineered and meticulously finished for smooth operation and lasting durability. In our combination lock models, we've refined every gap and detail to achieve the industry's finest tolerances — delivering a superior user experience with every use. Internally, our locking mechanisms are built with substantially heavier and more robust materials than 99% of competing products on the market, ensuring unmatched strength and reliability. At Sende, quality and security are never compromised — because we believe what matters most deserves the very best.

Every disc lock in our lineup is entirely self-developed — from concept to completion. Unlike anything else on the market, each model features a distinctive design language and a proprietary internal structure that sets it apart from the crowd. Breaking away from conventional disc lock designs, we've reimagined both form and function — achieving major breakthroughs in aesthetics and mechanical architecture. The result is a collection that not only looks exceptional but delivers superior performance and reliability, redefining what a disc lock can be.
