Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard specifies the safety technical requirements for electric bicycles equipped with electric drive or electric aid functions. It applies to fully assembled two-wheeled vehicles intended for the Chinese market, including those used for commercial logistics and rental services. It does not apply to electric mopeds or motorcycles, which are covered by other standards such as GB 24155.
Technical requirements
The standard outlines comprehensive safety requirements across several domains. For whole vehicle safety, it defines limits for maximum speed, braking performance, and total vehicle mass, distinguishing between lead-acid and other battery types. It also mandates specific dimensional limits and pedal riding functionality for certain models. In terms of electrical safety, the standard specifies requirements for control systems, including brake power-off, overcurrent protection, and anti-loss-of-control functions. It sets strict parameters for motor rated continuous output power and battery voltage limits to ensure safe operation. A significant update in this version is the introduction of fire resistance and flame retardancy requirements for non-metallic materials, alongside a new limit on the plastic proportion of the total vehicle mass. Manufacturers must ensure materials meet specific vertical burning test standards to prevent fire hazards. Additionally, the standard introduces mandatory BeiDou navigation satellite system (BDS) positioning and dynamic safety monitoring capabilities for commercial e-bikes. It also enforces strict anti-tampering measures for batteries, controllers, and speed limiters to prevent unauthorized modifications.
Testing methods
Testing methods include road and bench tests for speed limits, braking distance, and mechanical strength (vibration and impact tests for frame/fork assemblies). Electrical safety is verified through short circuit protection, overcurrent, and motor power tests. Fire resistance is evaluated using vertical burning tests per GB/T 5169.16. Anti-tampering features are rigorously checked using specified operational methods, decoders, and physical inspections to ensure compliance.
FAQs
What products are regulated under GB 17761-2024?
It regulates electric bicycles with electric drive or electric aid functions, including those used for commercial logistics and rental services. It does not cover electric mopeds or motorcycles.
Are there any updates from the previous version of GB 17761?
Yes, the 2024 version introduces new requirements for plastic proportion, BeiDou positioning, dynamic safety monitoring, and enhanced anti-tampering measures. It also updates vehicle mass limits and fire resistance testing.
Does GB 17761-2024 require BeiDou navigation for all e-bikes?
Commercial e-bikes must have a BeiDou module installed with anti-tampering features. For other types, the design must include a BeiDou module, but consumers can choose whether to retain it at the time of sale.
