给电动自行车改装踩“刹车”

Core Viewpoint - The implementation of the new electric bicycle safety technical specification (GB17761-2024) on September 1 marks a critical turning point in addressing the dangers associated with electric bicycle modifications, emphasizing safety as the primary concern for users [1][3]. Group 1: Current Situation and Challenges - The current social ownership of electric bicycles in China is approximately 380 million, equating to one bicycle for every four individuals [3]. - Illegal modifications, such as decoding speed limiters to achieve speeds of up to 80 km/h and installing high-capacity lithium batteries, pose significant safety risks, including increased accident rates and fire hazards [3]. - Speeding is identified as a primary cause of accidents involving electric bicycles, with reports of illegal street racing and specially modified models for students raising concerns [3]. Group 2: New Regulations and Safety Measures - The new regulations focus on systematic governance, enhancing standards, and regulatory enforcement to improve safety across all aspects of the electric bicycle industry [3][4]. - Specific measures include standardizing fire resistance for non-metal materials, limiting the use of plastic to no more than 5.5% of the total vehicle weight, and introducing anti-tampering requirements for speed limiters and battery systems [4]. - An innovative "speed cut-off" mechanism will automatically stop the motor when the speed exceeds the limit, aiming to prevent dangerous modifications [4]. Group 3: Goals and Public Responsibility - The overarching goal is to transition the electric bicycle industry from unregulated growth to a phase driven by safety, innovation, and quality competition [4]. - The emphasis is on establishing comprehensive standards and regulations to ensure road safety and promote responsible behavior among users, such as obeying traffic signals and wearing helmets [4].
