--- Ningbo Longyixiang: A Leader in Aluminum Alloy Frames ---
• Commitment to Quality and Innovation:
Ningbo Longyixiang Vehicle Industry Co., Ltd. has built its reputation on a relentless pursuit of quality and innovation since its founding in 1998. Over the past 25 years, the company has evolved from a small workshop in Cixi, Zhejiang, into a globally recognized manufacturer of high-performance aluminum alloy electric bicycle frames. One standout example of its commitment to excellence is its collaboration with a major European e-bike brand, which faced recurring issues with frame deformation under heavy loads and harsh weather conditions. After analyzing the problem, Longyixiang redesigned the frame using 6061-T6 aerospace-grade aluminum alloy, integrated a dual-process system of inert gas shielded welding (MIG) and solution treatment + artificial aging heat treatment, and reinforced critical stress points such as the head tube and rear fork. The result? A frame that passed rigorous CE certification tests, including 10,000-cycle fatigue testing and extreme temperature exposure, with zero structural failures. This case not only solidified the client’s trust but also led to a three-year bulk order agreement. Longyixiang’s R&D team further enhanced the design by incorporating a wrapped lithium battery housing structure, reducing impact risks by over 70%—a feature now standard across its premium models. Their continuous investment in R&D, including pilot projects on 3D-printed aluminum components and lightweight composite joints, ensures they stay ahead of industry trends while maintaining unmatched reliability.
• Diverse Product Range for Every Need:
Longyixiang’s product portfolio exemplifies its ability to meet diverse global market demands through strategic diversification and deep customization. A real-world success story comes from a Japanese urban mobility startup seeking a compact, foldable e-bike frame for last-mile delivery services. The client required a frame that could withstand daily wear-and-tear in dense city environments while enabling one-second folding for easy storage. Longyixiang delivered a custom-designed folding bike frame using ultra-thin yet high-strength 6061-T6 aluminum tubing, precision laser-cut joints, and a patented hinge mechanism. The final prototype reduced folding time to just 0.8 seconds and passed drop tests simulating 1.5-meter falls—exceeding JIS standards. The startup launched the model in Tokyo and Osaka within six months, achieving a 40% increase in delivery efficiency and winning a national green transport award. Beyond this, Longyixiang has supplied mountain bike frames to a U.S.-based adventure tour operator, shock-absorbing frames for French urban commuters, and even specialized tricycle frames for elderly mobility programs in Germany. Each project leverages Longyixiang’s full-chain capability—from concept sketch to mass production—demonstrating how their diversified offerings are not just products, but tailored solutions that solve real-world challenges. With over 150 SKUs and a 98% customer retention rate across international markets, Longyixiang proves that variety, when backed by engineering precision, becomes a competitive advantage.

• Quality Control and Manufacturing Standards:
A cornerstone of Longyixiang’s credibility lies in its stringent quality control protocols and adherence to international manufacturing standards. In 2022, the company underwent a third-party audit by TÜV Rheinland, a globally respected certification body, which validated its entire production chain against ISO 9001:2015 and IATF 16949 automotive quality management systems. One notable case involved a batch of urban commuter frames ordered by a German retailer. During initial inspection, minor dimensional deviations were detected in 3% of units due to thermal expansion during welding. Thanks to Longyixiang’s real-time monitoring system—powered by IoT-enabled sensors embedded in its precision welding robots—the issue was flagged immediately. The company halted production, recalibrated parameters, and retested every unit before shipment. The corrected batch achieved 100% compliance with EN 15194 safety standards and received full approval. This incident underscored the effectiveness of their three-tier inspection process: raw material verification (including spectroscopic analysis), in-process monitoring (with AI-driven visual inspection), and post-production testing (impact resistance, load capacity, and stability simulations). Moreover, all frames are certified with CE, CPSC, and JIS marks, ensuring seamless market access across Europe, North America, and Japan. These robust systems don’t just prevent defects—they build long-term trust, as evidenced by repeat orders from clients like a Danish e-bike OEM that has partnered with Longyixiang for five consecutive years without a single quality-related complaint.
• Customization and Flexibility in Production:
Longyixiang excels in delivering customized solutions that go beyond standard catalog offerings, making it a preferred choice for brands seeking unique differentiation. A prime example is their work with a U.S.-based shared e-bike provider aiming to launch a fleet of 5,000 smart bikes across California cities. The client needed frames compatible with integrated GPS trackers, anti-theft locks, and solar charging ports—all while maintaining a sleek, modern look. Longyixiang responded with a fully modular frame design featuring pre-drilled mounting points, internal cable routing channels, and an adjustable seat post for varied rider heights. They also developed a proprietary surface treatment that resists UV degradation and graffiti, crucial for outdoor fleets. From concept to first delivery, the project was completed in just 10 weeks—a feat made possible by Longyixiang’s agile production line and in-house tooling capabilities. The client reported a 30% reduction in maintenance costs and a 95% user satisfaction rate in post-launch surveys. Another case involved a Japanese luxury e-bike brand requesting a limited-edition Harley-style frame with hand-polished finishes and carbon fiber accents. Longyixiang combined CNC machining with artisanal polishing techniques and used a hybrid aluminum-carbon composite in the swing arm, resulting in a frame that weighed 2.3kg yet supported up to 150kg. These examples highlight how Longyixiang’s flexibility isn’t just about size or shape—it’s about understanding the brand identity, technical requirements, and end-user experience to deliver truly bespoke solutions. With a dedicated customization team and a 90-day turnaround guarantee on prototypes, Longyixiang has become synonymous with ‘whatever the customers need, we produce.’
