China’s e-bike revolution is generating global lessons in what happens when adoption outpaces regulation. A new report from the Institute for Transportation and Development Policy (ITDP), published April 7, documents how the explosive growth of electric bicycles across Chinese cities has created a cascade of infrastructure, safety, and governance challenges that other countries are now racing to avoid.
The numbers are staggering. China now has an estimated 350 million e-bikes on its roads—more than the total number of cars in the country. In major cities like Shenzhen, Hangzhou, and Chengdu, e-bikes account for over 30 percent of all daily trips. What began as an affordable mobility option for workers priced out of car ownership has evolved into a dominant urban transport mode that existing infrastructure was never designed to handle.
What Went Right—and What Went Wrong
China’s e-bike adoption story is fundamentally a success. E-bikes offered a low-cost, low-emission alternative to cars and motorcycles at precisely the moment Chinese cities were choking on traffic congestion and air pollution. For millions of delivery workers, commuters, and families, e-bikes provided mobility that was faster than public transit, cheaper than taxis, and more practical than traditional bicycles for trips over five kilometers.
The problems emerged because this adoption happened faster than any government anticipated. City planners who built infrastructure for a roughly 50-50 split between cars and traditional bicycles suddenly found themselves managing roads where e-bikes—traveling at speeds of 25 to 50 km/h—outnumbered both. The ITDP report identifies several key challenges that resulted from this mismatch.
First, existing bike lanes were too narrow and too slow for the volume and speed of e-bike traffic. Conflicts between e-bikes, traditional cyclists, and pedestrians increased sharply. Second, parking infrastructure was virtually nonexistent. Sidewalks, building entrances, and public spaces became cluttered with parked e-bikes, creating accessibility problems and fire hazards from battery charging. Third, inconsistent national standards meant that many e-bikes on Chinese roads exceeded legal speed and weight limits, blurring the regulatory line between bicycles and mopeds.
Why This Matters Outside China
China’s experience is a preview of challenges that Western cities are beginning to encounter. E-bike sales are surging across Europe and North America, driven by the same forces—urban congestion, climate awareness, and improving technology—that fueled China’s boom. The United States alone saw e-bike sales increase by over 60 percent between 2023 and 2025, and multiple cities have launched major rebate programs to accelerate adoption further.
The regulatory responses in the US are already varied and sometimes contradictory. New Jersey recently signed the strictest e-bike law in America, requiring registration and insurance for certain e-bike classes. California has introduced new safety requirements focused on lighting and visibility. Other states have minimal or no e-bike-specific regulations, creating a patchwork that manufacturers and riders must navigate.
The ITDP report argues that cities in Europe and North America have a narrow window to learn from China’s experience and build appropriate infrastructure and regulations before their own e-bike populations reach critical mass. Retrofitting infrastructure after the fact—as China is now doing—is far more expensive and disruptive than planning proactively.
Key Lessons From the ITDP Report
The report identifies several best practices drawn from Chinese cities that have managed the transition most effectively.
Dedicated e-bike lanes separated from both pedestrian paths and car traffic produced the biggest safety improvements. Cities that simply widened existing bike lanes saw limited benefit because speed differentials between traditional bikes and e-bikes remained a source of conflict. The most effective infrastructure designs created three separate zones: pedestrian sidewalks, traditional bike lanes, and e-bike lanes with capacity for overtaking.
Centralized charging and parking hubs reduced sidewalk clutter and battery fire risk. Cities like Hangzhou installed neighborhood charging stations where residents could park and charge e-bikes safely, using the same model as public EV charging but scaled for two-wheelers. The fire safety dimension is critical—lithium-ion battery fires in residential buildings have become a serious problem in cities where e-bike owners charge batteries inside apartments.
Speed-tiered regulations that distinguish between low-speed e-bikes (under 25 km/h), mid-speed e-bikes (25-45 km/h), and high-speed e-mopeds proved more effective than blanket rules. Each category carries different infrastructure access, licensing, and equipment requirements. This tiered approach allows cities to accommodate the full range of e-bike users while maintaining appropriate safety standards for each speed class.
What This Means for You
If you ride an e-bike—or are considering buying one—China’s experience carries several practical takeaways.
Second, invest in proper battery safety. The ITDP report highlights battery fires as the most serious e-bike safety issue globally. Always charge your e-bike with the manufacturer-supplied charger, never leave batteries charging unattended overnight, and store batteries away from flammable materials. Replace damaged batteries immediately rather than continuing to use them. Our e-bike maintenance guide covers battery care in detail.
Third, advocate for better infrastructure in your community. The most effective way to improve e-bike safety is not more restrictive regulation—it is better infrastructure. Contact your local transportation department, attend city planning meetings, and support organizations that advocate for protected cycling infrastructure. The cities that invested in dedicated e-bike lanes before adoption surged are now reaping the benefits of safer, more orderly urban mobility.
China’s e-bike revolution proves that two-wheeled electric vehicles can fundamentally transform urban transportation for the better. The challenge is ensuring that the infrastructure and rules of the road keep pace with the riders.
