Certain pedal-assist bicycles may be legally operated on New York City streets.
Pedal-assist bicycles are defined as bicycles that have fully operable pedals and an electric motor of less than 750 watts (1 horsepower). The electric motor can only engage when the operator is pedaling and going less than 20 miles per hour, and disengages or stops to function when the operator brakes, stops pedaling, or when the bicycle reaches a speed of 20 miles per hour. Pedal-assist bicycles cannot be equipped with any throttle capacity or have additional motorized equipment attached to it.
The pedal-assist bicycle must have an original label, provided by the bicycle or electric motor manufacturer, that states the maximum motor-assisted speed and motor wattage of the bicycle. Pedal-assist bicycles that have been modified are not considered to be pedal-assist bicycles and may not be operated on NYC streets.
