Defines bicycles with electric assist and establishes regulations for such bicycles

This bill defines "bicycles with electric assist" (e-bikes) under New York's Vehicle and Traffic Law and establishes specific operating rules for them. It adds e-bikes to the legal definition of bicycles, clarifies they are not motor vehicles, and sets a maximum 5 mph speed limit when riding on sidewalks (only when necessary for accessing adjacent property, work, or snow removal). The law explicitly states local governments may still create their own e-bike regulations. It directly affects e-bike riders, pedestrians, and local authorities managing sidewalk use.
