The "Mirror-and-Adjust" approach of the belt-driven bicycle arises from the need to refine and elevate the brand. It is grounded in innovation and self-confidence, focuses on the audience, and respects the "right to know." Guided by the "Three Nos" (no chain drop, no deformation, no slippage), it courageously faces controversies and launches an in-depth documentary-style discussion on the issue of "transformation." Following the central theme of "transforming without deforming," it reflects inwardly and furthers understanding.
Due to the inherent nature of the raw materials, success and failure are two sides of the same coin. On one hand, it contributes to the lightweight and agile advantages of the belt-driven bicycle, but on the other, it also raises concerns. Easy deformation, slippage, and chain dropping have become the most worrisome issues for users, hitting a nerve. It’s undeniable and unavoidable that these problems did exist when the belt-driven bicycle was first introduced—and they remained unresolved for quite some time. However, with increased R&D efforts, manufacturing standards improved from ordinary to fiber-core belts, and the precision of the belts has been continuously refined. Generally speaking, the industry-standard belts undergo nearly 10,000 stretch tests to find the optimal solution, thus avoiding issues like deformation and the subsequent problems of slippage and chain drop.
In addition, there are certain misconceptions among users about the belt-driven bicycle. The transmission principle of the belt-driven bicycle is fundamentally different from that of motor vehicles. The former involves a closed-loop belt with evenly spaced teeth on the inner surface running within grooves, paired with pulleys that have corresponding teeth. During operation, the teeth of the belt engage with the grooves of the pulley to transmit motion and power, whereas the latter lacks such grooves. As belt technology continues to advance, the engagement mechanism becomes tighter and more stable, completely resolving the issues of slippage and chain drop. It is reported that Shenzhen Two Wheels Co., Ltd. has earned widespread acclaim both within and outside the industry with its "0.01 mm Precision" (where one "silk" equals 0.01 mm, approximately 1/5 the diameter of a human hair) technology, bringing the concept of "Never Chain Drop*" closer to reality.
*Friendly Reminder: "Never Chain Drop" generally means, under normal circumstances compared to chain-driven bicycles, the chance of chain drop is close to zero, lasting at least 100,000 kilometers, including the belt’s lifespan—but does not cover accidents or special circumstances.
