9月1日，中国电动自行车行业迎来一场历史性变革——新版《电动自行车安全技术规范》(GB17761— 2024)(以下简称"新国标")正式实施。 这项关乎全国超3亿辆电动自行车的新国标，直指火灾风险与非法改装两大安全痛点。一方面，新国标 强化了对非金属材料防火阻燃性能的要求，限制塑料使用量，从源头上减少易燃材料的使用；另一方 面，要求企业对电池组、控制器和限速器采用"三位一体"的防篡改设计，从根本上杜绝改装可能。 "3C认证和生产许可证审核趋严，叠加环保监管压力，电动自行车行业在新国标下将加速洗牌，产能将 向头部企业集中。"广西电动车行业协会执行会长钱震向《证券日报》记者表示。 设置过渡期显政策温度 电动车国标修订于2018年。彼时电动自行车电池仍以铅酸为主，整车车体自重需小于或等于55千克，并 要求必须具备脚踏骑行功能。7年过去，车速、重量和锂电池能量密度加速增长，标准却一直滞后。据 北京交警统计，涉电动自行车伤亡事故中，近六成车辆超出原设计时速。换句话说，旧标准已无法覆盖 新技术、新材料所带来的新风险。 新国标的出台，不是为了限制行业发展，而是以更高、更细的"安全护栏"将狂奔的3亿辆车拉回正轨。 政策为新国 ...
