Core Viewpoint - The new mandatory national standard for electric bicycles in China will be implemented starting September 1, aiming to enhance safety and reduce fire hazards associated with electric bicycles, which currently have a total ownership of approximately 380 million units in the country, equating to one electric bicycle for every four people [1][13]. Group 1: Key Changes in Standards - The new standard introduces a maximum speed limit of 25 kilometers per hour for electric bicycles, with automatic power cut-off if this speed is exceeded [12]. - Enhanced safety features include a matching function between the battery pack and controller, preventing operation if mismatched, thereby improving overall safety [6][9]. - The standard mandates that the total mass of plastic components in electric bicycles must not exceed 5.5% of the total vehicle mass, aimed at reducing fire risks and toxic smoke during incidents [23][25]. Group 2: Fire Safety Enhancements - The new regulations impose stricter fire resistance requirements for non-metal materials, including plastics and textiles, to minimize ignition risks and the severity of fires [20][18]. - A significant concern is that electric bicycle fires can escalate rapidly, with temperatures exceeding 500°C and producing large amounts of toxic smoke, which is a leading cause of fatalities in such incidents [15][16]. - The standard also requires electric bicycles to be equipped with high-temperature resistant vehicle identification codes to facilitate traceability in case of fires [26][28]. Group 3: Technological Improvements - The new standard incorporates advanced features such as BeiDou positioning and dynamic safety monitoring to enhance proactive safety measures [29]. - Electric bicycles must now include communication modules to upload dynamic information to management platforms, allowing for immediate alerts regarding safety hazards [34][36]. - Compliance with national information security standards for data transmission is also mandated, ensuring user data protection [38]. Group 4: Quality Assurance Measures - The new standard emphasizes the need for manufacturers to establish comprehensive quality assurance systems that align with their production capacities, ensuring consistent product quality [40]. - As of now, 21 manufacturers have had 52 models certified under the new standards, indicating a proactive approach within the industry to meet these requirements [42][44].
