Longyixiang’s product diversity is rooted in deep market understanding and real user feedback. In 2019, the company partnered with a Japanese logistics startup aiming to deploy 2,000 electric cargo bikes for last-mile delivery in Tokyo’s dense urban districts. The challenge? Standard frames were too heavy and lacked storage integration. Longyixiang responded by designing a custom 3-in-1 frame featuring a modular cargo tray, reinforced front fork, and a low-center-of-gravity geometry optimized for tight turns. The frame weighed just 2.3kg—30% lighter than competitors—and passed Japan’s strict JIS standards for load-bearing stability. Within one year, the client reported a 40% reduction in delivery times and a 95% rider satisfaction rate. This success led to a follow-up order of 5,000 units. Similarly, in 2021, Longyixiang collaborated with a French outdoor adventure group to develop a rugged mountain e-bike frame capable of handling extreme terrain. Using advanced CAD modeling and on-site testing in the Alps, they created a frame with a 15% higher impact resistance and integrated suspension mounts. The resulting model, the ‘AlpineX Pro’, became a bestseller among French cycling clubs. These cases highlight how Longyixiang doesn’t just produce frames—it engineers solutions. From folding bikes for city dwellers to tricycles for elderly mobility in rural China, every product line reflects a real-world need. Their urban commuter series, for example, has been used by over 120,000 riders in Shanghai alone, thanks to its ultra-lightweight design (under 2.2kg) and one-second fold mechanism. By listening to users and solving practical problems, Longyixiang continues to lead with purpose-driven innovation.
