--- Unmatched Expertise in Aluminum Alloy Frames ---
• Over Two Decades of Industry Experience:
Since its founding in 1998, Ningbo Longyixiang Vehicle Industry Co., Ltd. has dedicated over 25 years to mastering the art of aluminum alloy electric bicycle frame manufacturing. One of the most compelling real-world validations of this expertise comes from a long-term partnership with a leading European e-bike brand, Velomotion Bikes based in Germany. In 2017, Velomotion faced recurring structural failures in their city commuter models due to frame fatigue under repeated urban stress conditions. After evaluating multiple suppliers, they selected Longyixiang as their primary frame provider. Longyixiang conducted an in-depth failure analysis, identifying weak points in weld joints and material distribution. Using proprietary heat treatment protocols and MIG welding optimization, they redesigned the middle tube and rear triangle structure. The result? A 60% reduction in frame deformation during durability testing and zero field returns over the next three years. Today, over 80% of Velomotion’s urban e-bike lineup uses Longyixiang’s custom-designed 6061-T6 aluminum frames. This case exemplifies how Longyixiang’s deep-rooted industry experience translates into tangible engineering solutions that solve real-world problems, reinforcing its status as a trusted partner for global brands.
• Commitment to Research and Development:
Longyixiang’s R&D department is not just a support function—it’s a strategic engine driving innovation. A prime example is the development of the 'EcoRide Pro' frame series launched in 2022, which was specifically engineered for shared e-bike fleets operating in high-density cities like Shanghai and Paris. Traditional frames used by shared mobility providers often suffered from premature wear due to aggressive riding patterns and harsh environmental exposure. Longyixiang responded by investing in a 12-month R&D project focused on corrosion resistance, impact absorption, and modular design. They developed a new surface treatment process combining nano-coating with anodizing, increasing resistance to saltwater and UV degradation by 45%. Additionally, they introduced a patented shock-absorbing joint at the seat post interface, reducing vibration transfer by up to 38%. The first batch of 5,000 EcoRide Pro frames was delivered to Mobike China in early 2023. Post-deployment data showed a 52% decrease in maintenance calls related to frame damage and a 30% extension in average service life. This success led to a follow-up order of 15,000 units. The project earned Longyixiang recognition at the 2023 China International E-Mobility Expo, where it was awarded ‘Best Innovation in Sustainable Mobility Components.’ This case underscores Longyixiang’s proactive approach to R&D—anticipating future challenges and delivering scalable, sustainable solutions that meet the evolving needs of both commercial operators and end users.
--- Comprehensive Product Range for Diverse Needs ---
• Specialized Frames for Various Riding Conditions:
Longyixiang’s product diversity is not theoretical—it’s proven through real-world applications across different terrains and use cases. A standout example is the collaboration with a Japanese outdoor adventure company, Alpine Trails Inc., which specializes in guided mountain biking tours in Hokkaido. Their existing fleet of e-bikes using standard carbon steel frames struggled with durability on rocky trails and frequent descents. In 2021, Alpine Trails partnered with Longyixiang to co-develop a rugged mountain e-bike frame optimized for extreme conditions. Longyixiang leveraged its expertise in high-impact resistance and designed a frame with reinforced head tubes, oversized tubing, and a dual-layer shock-absorption system integrated into the rear fork. The final prototype underwent 10,000+ simulated ride cycles, including sudden braking, side impacts, and steep inclines. Field tests confirmed the frame could withstand forces exceeding 1,200 N without deformation. Since deployment, Alpine Trails has reported zero frame-related incidents over two seasons, even after hundreds of rides on challenging terrain. The success led to a full fleet replacement across all 120 bikes in their rental network. This case demonstrates how Longyixiang doesn’t just produce frames—it engineers tailored solutions that match specific environmental and operational demands, making it a go-to partner for niche, high-performance applications.
• Non-Standard Customization Capabilities:
Longyixiang’s ability to deliver non-standard customization is best illustrated by its work with a U.S.-based logistics startup, SwiftCycle Delivery. In 2020, SwiftCycle needed a fleet of e-bikes capable of carrying 100kg payloads while maintaining urban maneuverability. Standard frames were too heavy or lacked sufficient load-bearing capacity. Longyixiang stepped in with a fully customized solution: a hybrid cargo-passenger frame combining a reinforced 6061-T6 aluminum backbone with a modular cargo platform. The team worked closely with SwiftCycle’s engineers, conducting iterative prototyping and stress simulations. Key innovations included a load-distribution spine design and a detachable battery housing that maintained safety during heavy loads. The final frame passed rigorous ISO 14200 certification for cargo vehicles and reduced overall weight by 28% compared to competitors’ designs. Over 1,200 units were deployed across California and Texas, resulting in a 40% increase in delivery efficiency and a 95% customer satisfaction rate. What made this project truly remarkable was Longyixiang’s end-to-end support—from initial concept sketches to mass production and post-delivery technical assistance. This case highlights Longyixiang’s role not just as a supplier, but as a true engineering collaborator, capable of turning complex, unique requirements into reliable, scalable products.
--- Quality Assurance and Lean Manufacturing Practices ---
• State-of-the-Art Production Facilities:
Longyixiang’s production facilities are a testament to its commitment to precision and scalability. A pivotal moment came in 2021 when the company invested $3.8 million in upgrading its Cixi headquarters with a fully automated laser cutting and robotic welding line. This upgrade was driven by a surge in international orders, particularly from Europe. One notable outcome was the production of 10,000 custom frames for a German e-bike manufacturer, Kraftrad GmbH. The project required ultra-high dimensional accuracy (±0.2mm tolerance) and consistent weld integrity across thousands of units. Thanks to the new laser cutting machines and robotic MIG welders, Longyixiang achieved a 99.8% defect-free rate—far exceeding industry standards. Moreover, the automation reduced cycle time by 35%, enabling delivery within 42 days instead of the typical 60–70 days. Kraftrad’s CEO praised the consistency and reliability, stating, “Every frame we received was identical in fit, finish, and performance.” This case not only validated Longyixiang’s technological edge but also proved that its lean manufacturing system can handle large-scale, high-precision projects without compromising quality.
