Core Points - The new national standard for electric bicycles, GB 17761—2024, will be implemented on September 1, 2024, introducing significant changes to enhance safety and performance [1][3]. Group 1: Key Changes in the New Standard - The new standard strengthens fire resistance requirements for non-metal materials [1]. - The total mass of plastic used in electric bicycles must not exceed 5.5% of the total vehicle weight [1]. - New requirements for low-speed torque of electric motors have been added [1]. - Enhanced anti-tampering requirements for battery packs, controllers, and speed limiters are included [1]. - The braking performance requirements have been improved, aiming to reduce braking distance by half and prevent skidding in wet conditions [2]. - The weight limit for electric bicycles using lead-acid batteries has been increased from 55 kg to 63 kg to improve range [1][2]. - Manufacturers are required to provide quality assurance capabilities and product consistency [1]. - Electric bicycles must be equipped with BeiDou positioning, communication, and dynamic safety monitoring functions [1][2]. - The installation of pedal riding devices is no longer mandatory for all models, while the installation of rearview mirrors is encouraged [1]. - Manufacturers must specify the recommended service life of electric bicycles on the nameplate and product certificate [1]. Group 2: Transition and Compliance - All newly produced electric bicycles must comply with the new standard by September 1, 2025, with a three-month sales transition period for vehicles produced under the old standard [3]. - Consumers who have already purchased non-compliant vehicles will not be forced to discard them; local governments may implement policies to encourage upgrades [4]. Group 3: Consumer Guidance for Purchasing - Consumers should look for CCC certification on electric bicycles, indicating compliance with mandatory national standards [5]. - Each electric bicycle must have a product certificate, allowing consumers to verify the model and vehicle identification number [7]. - To confirm the authenticity of the product certificate and CCC certification, consumers can scan the QR code on the certificate or visit the national certification information platform [7].
