Comprehensive Interpretation of the New National Standard for Electric Bicycles in Beijing (Effective September 1, 2025)

I. Detailed Explanation of Core Revisions to the New National Standard

The National Standardization Administration officially released the "Safety Technical Specifications for Electric Bicycles" (GB 17761-2024) on December 31, 2024. This standard will be fully implemented as a mandatory national standard for the electric bicycle industry starting from September 1, 2025. The revision is a systematic upgrade based on the version from 2018 and involves significant adjustments in eleven key areas:

In terms of fire safety, new standards impose stricter grading requirements on non-metal materials' flame retardancy performance. Specifically, the combustion rate limit for seat cushion materials has been adjusted from ≤100mm/min to ≤80mm/min; vertical burning damage length requirements for textile decorative materials must not exceed 150mm; and electrical circuit wire insulation layers must pass an incandescent wire test at temperatures up to 850℃. These detailed indicators will significantly enhance vehicle fire safety under extreme conditions.

Regarding overall vehicle structure, new regulations specify that plastic components cannot account for more than 5.5% of total vehicle weight to mitigate material abuse risks during lightweighting processes. Additionally, considering lead-acid battery characteristics, the maximum weight limit for vehicles equipped with lead-acid batteries has been raised from 55kg to 63kg to better meet actual usage needs.

For power systems, new technical parameters have been introduced: motor low-speed torque should not be less than85% of rated torque; no-load back electromotive force fluctuation rate should be ≤5%; three-phase inductance value difference coefficient should be ≤10%. The introduction of these indicators will effectively regulate motor production quality and ensure stable and consistent power output.

II. Implementation Details During Transition Period

To ensure smooth industrial transition, authorities have developed a phased implementation strategy. An eight-month transition period is set during production (from December31 ,2024,to August31 ,2025), allowing companies to choose between adhering to either old or new standards during this time frame . Notably ,all newly produced vehicles must comply with GB17761 -2024 requirements startingSeptember1 ,2025 . An additional three-month buffer period is granted during sales until November30 ,2025 ,allowing dealers timeto clear out inventory produced under previous standards . It’s importantto note that consumers who have already purchased non-compliant vehicles won’t face forced elimination but are advisedto pay attentiontothe replacement subsidy policies launched by local governments . For instance,inBeijing,a subsidyofup650 yuan canbe obtained throughthe “Jingtong” app when applyingfor replacements between February8andDecember10in2025(basic subsidy500yuan + lithium-to-lead acid substitution100yuan + battery health assessment50yuan).

III.Vehicle Purchase Guide & Registration Regulations nConsumers needto focuson two key identifiers when purchasing : CCC certification markand product qualification certificate.The updated qualification certificateshould clearly indicate recommended service life(usually five-eight years)and Beidou module options.For commercial usevehicles,the installationof Beidou positioning functionis mandatory ; private users maychoose whetheror nottoretainthismodule. nAsfor registrationrequirements,startingsinceSeptember1st,u00202025,the public security organswill strictlyverifyvehicles according tothe new nationalstandard.Materials required include: purchase invoice(date afterJanuary1st,u00202025),vehicle compliancecertificate(markedwithGB17761-20...
