Engineered for high durability, water-resistant performance, and versatile urban utility.
As modern urban environments face increasing congestion, the transition to light electric vehicles (LEVs)—such as commuter e-bikes, electric cargo scooters, and leisure electric tricycles—has accelerated. However, operating within commercial logistics, food delivery, and daily metropolitan commuting demands equipment that resists adverse weather. Among these, environmental ingress remains the leading cause of electrical component failure, system degradation, and battery pack thermal risks.
An IPX4 ingress protection rating indicates that the vehicle is protected against water splashes from any direction. For ODM (Original Design Manufacturer) projects, designing to an IPX4 standard is not merely a marketing label, but a strict engineering mandate. It involves sealing sensitive system layers, including the Battery Management System (BMS), motor controllers, displays, and wiring harnesses, ensuring operational reliability under rainy and humid conditions.
How Aurora Electric Vehicle Shandong Co., Ltd. implements robust IPX4 layers across micro-mobility categories.
Utilizing high-grade silicone and polyurethane gaskets at all enclosure joints (battery tray, controller compartment, and dashboard). Labyrinth seal structures prevent high-velocity water ingress.
To prevent internal condensation and pressure buildup caused by temperature fluctuations during operation, we install hydrophobic membranes that allow air exchange while repelling water molecules.
Sensitive PCBs (Printed Circuit Boards) inside controllers and displays are treated with multi-layer acrylic or silicone conformal coatings. High-vibration areas are fully potted with epoxy compounds.

Understanding regional demands, compliance regulations, and micro-mobility operations.
In Europe, electric power-assisted cycles (EPACs) must comply with EN15194 standards, which mandate strict waterproof safety and battery encapsulation. The CE mark is essential, ensuring components do not fail under typical maritime climate rains common in Northern and Western Europe.
US and Canadian municipalities increasingly mandate UL2272 (for personal e-mobility) and UL2849 (for electrical systems in e-bikes). IPX4 sealing prevents water intrusion that could cause short-circuits and thermal runaway in high-density lithium packs.
For high-intensity operations like food delivery in countries with monsoon seasons (e.g., Southeast Asia, India, Japan), water-resistant, durable cargo electric scooters are critical. IPX4 components minimize vehicle downtime and optimize return on investment (ROI) for fleet operators.
A decadelong legacy of quality, engineering, and manufacturing excellence in Linyi City, Shandong.
Founded in 2015, our electric bicycle manufacturing enterprise is located in Linyi City, Shandong Province, a core transportation hub connecting the Yangtze River Delta and the Bohai Economic Circle with prominent geographical advantages. As a professional manufacturer deeply rooted in the electric bicycle industry for over 10 years, we have grown from a small-scale production workshop to a comprehensive enterprise integrating R&D, production, sales, and after-sales service, witnessing and participating in the high-quality development of China's electric bicycle industry under the new national standard era.
Our development history is a journey of persistence, innovation, and continuous transcendence. Since our establishment, we have closely followed the industry trend and policy orientation. In 2019, when the new national standard for electric bicycles was officially implemented, we took the initiative to upgrade our production lines and R&D capabilities, optimizing product parameters to fully comply with the mandatory safety standards, including fire retardant performance, speed limit, and anti-tampering requirements.
Over the past decade, we have continuously expanded our production scale, built a standardized production base covering a large area, equipped with intelligent digital production lines, automatic assembly lines, and professional testing equipment. This realizes the standardized and efficient production of core components such as motors, batteries, and frames. Today, our annual production capacity has reached a high level, capable of meeting the diverse needs of domestic and foreign customers, and our products have been widely recognized in both the domestic market and overseas regions.
Consists of senior engineers with more than 10 years of experience in the electric bicycle industry. They focus on improving battery life, safety performance, and riding comfort, and have obtained multiple core patents related to motors and battery management systems (BMS).
Composed of skilled workers who undergo regular training. They implement every production process—from raw material inspection to finished product delivery—ensuring each electric vehicle meets our strict quality standards.
