CLASS ONE BICYCLE WITH ELECTRIC ASSIST: A bicycle with electric assist having an electric motor that provides assistance only when the person operating such bicycle is pedaling, and that ceases to provide assistance when such bicycle reaches a speed of 20 miles per hour.

Full Breakdown
Suffolk County Code § 319-51 splits bicycles with electric assist into Class 1 (motor assists only while the rider pedals, cutting off at 20 mph) and Class 2 (motor can propel the bike alone, also capped at 20 mph), tracking state Vehicle and Traffic Law § 102-c. Section 319-52 bars anyone 15 or younger from operating an e-bike or scooter, requires helmets for all riders, and prohibits operation on County-owned off-highway property, sidewalks, and roads posted above 30 mph. Separately, § 319-48 requires every lithium-ion battery sold for e-bikes or micromobility devices in the county to carry UL 2849, UL 2271, or EN 15194 certification, displayed on both the packaging and the device itself.
