CCTV exposed so-called “range extenders” for electric bicycles sold on major e‑commerce platforms that claim “solar + wind” charging while riding. Tests and teardown showed tiny generators, thin wiring and a simple circuit delivering only ~2.9V in sunlight—far below claimed 12–125V specs—so real charging benefit is negligible. Experts from Xi’an Jiaotong University and industry sources warn the devices can create safety risks: electrical mismatch, reverse current, short circuits, leakage, fire,
Misleading range extenders can cause false security and unsafe modifications to e-bikes, creating liability and regulatory risks for manufacturers, sellers, and platforms. Tech professionals need to assess product claims, electrical compatibility, and safety testing to prevent fires, shorts, and compliance failures.

Amazon to stop selling 'hooligan e-bikes' in California
Shenzhen authorities dismantled an illegal operation that used live-streaming platforms to sell modified electric bicycles, detaining 12 suspects. Since China’s updated e-bike national standard took effect on Dec. 1, 2025, Shenzhen’s market regulators have opened 457 cases, seized 1,062 noncompliant e-bikes and 1,656 parts, fined 733,300 yuan, and referred three cases to police. The recent raid in Pingshan District recovered 592 vehicles — the largest seizure since the new standard — and involved coordination between market supervision, public security, and traffic police. The bust highlights enforcement challenges around e-bike safety, platform oversight, and illegal online sales channels. The case underscores regulatory and compliance risks for livestream commerce and last-mile mobility makers.

CCTV exposed so-called “range extenders” for electric bicycles sold on major e‑commerce platforms that claim “solar + wind” charging while riding. Tests and teardown showed tiny generators, thin wiring and a simple circuit delivering only ~2.9V in sunlight—far below claimed 12–125V specs—so real charging benefit is negligible. Experts from Xi’an Jiaotong University and industry sources warn the devices can create safety risks: electrical mismatch, reverse current, short circuits, leakage, fire, vehicle imbalance, injury in crashes, and may void insurance or violate regulations. Regulators and safety authorities have flagged illegal modifications and nonstandard products; buyers are advised not to install them.
