"Traditional locks, while somewhat effective in preventing theft, are often heavy and difficult to carry, which causes many bike owners to feel troubled when choosing a lock," said Thunder, the R&D Director at SINOX.

Unlike motorcycles, bicycles have different frames, and their usage is generally for shorter distances within urban areas. If we only focus on lock strength without addressing the pain points of cyclists in different scenarios, we might end up with a product design that "causes more trouble than it's worth" for users. Therefore, the SINOX team decided to address this issue by finding a lock solution that enhances security while being easy to carry.

After gaining a deep understanding of the needs of the urban cycling market, the SINOX team launched the world's first Hamburger Lock—“WL0798”—in 2021. The design inspiration for this lock came from its compact size when folded, resembling a hamburger, making it easy to carry. Through precise design calculations, the team ensured the optimal distance between lock plates and anchor point design, significantly enhancing the lock's flexibility and security. This innovative design not only breaks the stereotype of heavy traditional locks but also can secure 4 to 5 bicycles simultaneously, solving the anti-theft issue for group outings

The introduction of the Hamburger Lock not only earned SINOX the prestigious Reddot Design Award and Golden Pin Design Award but also garnered widespread attention in the market. This lock, while lightweight, provides excellent anti-theft protection and has received praise from numerous users. Previously, the term "Hamburger Lock" did not exist in the two-wheel market. After SINOX's breakthrough in the cycling market with its innovation, the term "Hamburger Lock" brought new vitality to our industry customers. With growing demand, the SINOX team further introduced a newly designed "Combination Hamburger Lock" (WL0790), enhancing both convenience and security.
