By the end of 2025, China’s electric bicycle market has quietly completed one of its most important regulatory transitions in years.
The updated national safety standard for electric bicycles, GB 17761-2024, is now fully in force. After a year of phased implementation, all newly manufactured and sold e-bikes must comply with the new rules, replacing the long-standing 2018 standard.
For riders, manufacturers, and delivery platforms alike, the changes reshape how electric bicycles are built, sold, and used, with a clear focus on safety, fire prevention, and tighter technical control.
The Safety Case Behind the New Rules
One of the key drivers behind the updated GB 17761-2024 standard was road safety. According to data referenced by the Chinese CDC (Collects and analyzes injury and mortality data, including traffic-related deaths), before recent rule changes an e-bike rider died on average every hour and five were injured in traffic accidents involving electric bicycles nationwide, underlining how widespread serious crashes had become.
Head injuries accounted for the majority of severe and fatal outcomes among e-bike riders, reflecting the risks when fast, heavy, or modified bikes interact with other road users. These concerns, combined with rising use by delivery drivers under pressure to go fast, pushed regulators to tighten speed limits, enhance braking and fire-safety requirements, and build in protections against illegal modifications that had previously allowed some bikes to reach speeds far above the earlier standard.
A Regulation That Is Now Fully in Force
The new standard was issued on December 31, 2024 and formally took effect on September 1, 2025. To avoid market disruption, regulators introduced a staged transition period.
Production of non-compliant electric bicycles ended on August 31, 2025. Retailers were permitted to sell remaining inventory slightly longer, but only until November 30, 2025.
As of December 2025, only electric bicycles that meet GB 17761-2024 and carry updated CCC (China Compulsory Certification) approval may legally be sold in China.
Speed Limits, This Time Without Loopholes
The most visible requirement remains the speed cap.
Electric motor assistance must cut off at 25 km/h. Once that speed is reached, the motor disengages. While this limit already existed under the 2018 rules, enforcement was uneven. Easy controller swaps and software tweaks allowed many bikes to operate far beyond legal thresholds, in some cases approaching motorcycle speeds.
The updated standard closes those loopholes. Manufacturers must now implement anti-tampering protections across controllers, motors, batteries, and speed limiters. Both physical modifications and electronic or software-based circumvention are explicitly addressed.
Regulators have also clarified that assistance cut-off does not apply braking. Riders retain full control of their brakes, and downhill coasting beyond 25 km/h is not restricted.
Fire Safety Moves to the Forefront
Fire risk is a central reason for the tighter rules.
Under GB 17761-2024, non-metallic materials may not exceed 5.5 percent of total vehicle weight, reducing the amount of flammable plastic used in e-bike construction. Seat cushion foam and other soft materials must also meet higher flame-retardant standards.
This does not mean a return to rigid or uncomfortable designs. Foam seats remain common, provided they meet the new safety thresholds. Metal saddles are not required.
Weight limits have also been refined. Electric bicycles using lead-acid batteries are capped at 63 kilograms, with different requirements applied to other battery types.
Braking, Visibility, and Everyday Safety
The standard strengthens braking performance requirements, including tighter stopping distance limits and higher reliability benchmarks.
Rearview mirrors are encouraged as a safety measure. They are excluded from official width and height measurements, allowing manufacturers design flexibility. Riders may also add mirrors themselves without affecting compliance.
Passengers and Practical Use
Passenger rules remain largely unchanged.
A maximum saddle length of 350 millimeters is used to dissuade carrying adult passengers. Child passengers are regulated locally, and many cities permit one child when a certified child seat is used.
Why the Reset Was Necessary
Over time, widespread illegal modifications blurred the line between electric bicycles and motorcycles. Higher speeds, heavier frames, and unregulated components increased accident risks and fire hazards, while complicating enforcement.
The new standard draws a clearer boundary. By tightening limits on speed, materials, weight, and tamper resistance, regulators aim to reduce accidents, improve fire safety, and bring consistency back to the market.
Market Impact
For most private riders, the changes are incremental rather than dramatic. New models tend to feel more regulated and less open to modification.
Commercial operators, particularly delivery fleets, face greater adjustments. Previous efficiency gains often relied on higher speeds and heavier loads. The updated framework prioritizes public safety over operational flexibility.
A More Regulated Road Ahead
With the transition period complete, China’s electric bicycle market has entered a more tightly regulated phase. The emphasis has shifted away from modification and speed, and toward safety, fire prevention, and predictable performance.
For a vehicle that has become deeply embedded in daily urban life, the message of GB 17761-2024 is clear: electric bicycles are no longer treated as informal transport, but as a regulated part of the traffic system itself.
