Under the global wave of lightweight and intelligent transformation in new energy transportation, aluminum alloy has become a core material for electric vehicles due to its high cost performance and weight reduction advantages. Ningbo Longyixiang Vehicle Industry Co., LTD., as a powerful enterprise with 27 years of experience in this field, takes technological innovation as its core and quality as its foundation, creating a full range of aluminum alloy lithium battery electric vehicle frame solutions. It has expanded from the Yangtze River Delta to the global market and has become a trusted partner in the industry.
With 27 years of dedicated accumulation, we offer a full range of solutions to meet diverse needs
Ningbo Longyixiang Vehicle Industry was founded in 1998, specializing in the research and development, production and manufacturing of high-quality aluminum alloy lithium battery electric bicycle frames. It is one of the earliest enterprises in China to focus on this niche field. Relying on the solid manufacturing foundation of Cixi, Zhejiang Province and the local digital transformation support policies, the company has built a modern production system covering an area of over 6,000 square meters, equipped with advanced equipment such as laser cutting and precision welding. Through a dual quality control system composed of technical departments and quality assurance departments, it ensures the accuracy and stability of each product.
Our product matrix comprehensively covers all categories including mountain bikes, city bikes, folding bikes, shock-absorbing bikes, Harley-style bikes, passenger and cargo bikes, tricycles, etc. We are particularly skilled at complex non-standard customization and can adapt to various size specifications from 0.5×1m to 1×3m and diverse scenarios according to customer needs, precisely meeting differentiated demands such as civilian commuting, commercial operations, and special functions. For many years, the company has adhered to the tenet of "service first, customer supreme, and integrity-based", and through the efficient collaboration of all departments, has achieved rapid response to orders and smooth delivery.
The three core technologies define the quality benchmark of high-end vehicle frames
Longyixiang has always focused on the coordinated optimization of materials, processes and structures, achieving triple breakthroughs in safety, lightweight and riding experience through technological innovation, meeting the core demands of high-end users for quality and long-term value
Ultimate safety guarantee: Made of 6-series high-strength aluminum alloy material, combined with laser swing welding technology, the porosity of the weld seam is controlled below 0.1%, and the frame structure is stabilized by heat treatment process. The frame has outstanding impact resistance and deformation resistance, effectively protecting the internal lithium battery from collision damage, reducing safety risks such as short circuits and fires, and maintaining vehicle stability in extreme scenarios such as sudden braking and jolting.
Significant lightweight advantages: Compared with traditional carbon steel frames, it achieves a weight reduction of 20% to 40% while ensuring strength, making vehicle acceleration more effortless and handling more flexible. It is especially suitable for frequent start-stop and climbing scenarios during urban commuting, significantly reducing riding fatigue.
Humanized riding experience: Incorporating ergonomic design, by optimizing the Angle of the riser, wheelbase and shock absorption structure, it reduces the pressure on the waist, back and buttocks during long rides. The frame rigidity is precisely tuned to ensure lower energy loss when applying force, balancing comfort and riding efficiency.
The global market layout builds an international cooperation network
In the domestic market, Longyixiang has been deeply rooted in the core area of the Yangtze River Delta, and has won the recognition of local customers with its stable quality and high cost-performance products. In the international market, through precise layout through multiple channels such as search engines and social media, the products have successfully entered mainstream markets such as Europe, America and Japan, and fully comply with international safety standards such as EU EN 15194, US CPSC 16 CFR 1512, and Japanese JIS D 9111. Passed the RoHS 2.0 Hazardous Substance Limitation and Battery safety certification, and received high praise from customers in more than 50 countries and regions around the world.
At present, the global new energy vehicle industry is booming, and the market size of aluminum alloy parts is continuously expanding. By 2024, the domestic related market size has reached 697.838 billion yuan. Ningbo Longyixiang will seize the momentum, continuously increase investment in research and development, focus on product iteration and upgrading, and build long-term and stable partnerships worldwide with more competitive technologies, products and services.
We sincerely invite domestic and foreign customers to visit and negotiate. Let's join hands to seize the development opportunities of new energy transportation and create a new future for the industry together!
