While the NYC law does not explicitly mention OSHA National Recognized Test Laboratories (NRTLs) with scope of recognition to UL 2849, UL 2272, and UL 2271, it does make a lot of sense these would be the approved certification organizations given the fact the US government has recognized some of...

Hello, Thank you for your questions. I will try to answer them succinctly. 1. The ebike with an AW motor, is it UL 2849 Certified? If not, it would not meet the recently passed NYC micromobility law. Clause 20 of UL 2849 describes the Motor and Motor Control safety requirements. There are...
