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.
