Amazon and UL sue Chinese e-bike makers over false UL certification

Published January 28, 2026

SEATTLE (BRAIN) — Amazon and UL are suing five e-bike and e-scooter companies, alleging they improperly labeled products with UL trademarks. 

The retailer and the testing company filed suit Jan. 23 against three Chinese companies, one Hong Kong-based company and one individual in the counterfeit case. The suit also lists between one and 10 unnamed defendants. 

Amazon and UL, in the case filed in the U.S. District Court for Western Washington in Seattle, say the defendants advertised and sold products bearing one of four registered UL trademarks in 2024 and 2025. 

“As a result of their illegal actions, defendants have infringed and misused UL’s IP; breached their contracts with Amazon; willfully deceived and harmed Amazon, UL, and their customers; compromised the integrity of the Amazon Store; and undermined the trust that customers place in Amazon and UL,” according to the complaint.

The complaint claims the various defendants conspired in the alleged counterfeiting scheme, which included registering as third-party sellers with Amazon. In registering as sellers, the defendants signed Amazon Services’ Business Solutions Agreement, which designates Washington state or federal courts as the appropriate venue for claims related to the sale of counterfeit products in the Amazon Store.

The complaint asks for actual damages and the impoundment and destruction of any products inappropriately bearing the UL trademarks, among other relief.  

Amazon and UL filed five similar cases in the same court in December. They have asked the court to assign and transfer all of them to the same judge.  

The defendants in the latest case are Jiangmen Meijiasheng Bicycle Co., Ltd.; Shenzhen Aibosi Sport Technology Co., Ltd.; and Guangzhou Aierfeile Sport Technology Co., LTD., all of China; and Hong Kong Manchester International Trading Co., LTD., of Hong Kong and Tang Shuhui, an individual.

The complaint lists seven specific models that were offered for sale on Amazon, under the Aipas and A4 brands. The suit also alleges some of the models that improperly bear the UL trademarks have been sold on aipasbike.com.
