Yes, electric tricycles are generally legal in the United States, but their use is subject to various federal, state, and local regulations. Here’s an overview of the key legal considerations: Federal Regulations Consumer Product Safety Commission (CPSC) Electric tricycles that meet certain criteria (e.g., maximum speed of 20 mph on level ground with motor assistance only) are classified as "low-speed electric bicycles" under CPSC regulations. These vehicles must have fully operable pedals and an electric motor of less than 750 watts (1 horsepower). Department of Transportation (DOT) If an electric tricycle exceeds the specifications for low-speed electric bicycles, it may be classified differently and subject to additional DOT regulations. State Regulations State laws can vary significantly regarding the use of electric tricycles. Common areas regulated include: Age Restrictions: Some states have minimum age requirements for operating electric tricycles. Helmet Laws: Many states require helmets for riders under a certain age or for all riders regardless of age. Licensing and Registration: While many states do not require a special license or registration for low-speed electric bicycles/tricycles, some might have specific requirements. Speed Limits: States may impose speed limits on where and how fast you can ride an electric tricycle. Where You Can Ride: Regulations often specify whether you can ride on sidewalks, bike lanes, or roads. Local Regulations Local municipalities may have additional rules governing the use of electric tricycles: 1 . Parking restrictions 2 . Specific paths/trails designated usage 3 . Noise ordinances Examples by State California: Classifies low-speed electric bicycles into three classes; Class 1 and Class 2 e-bikes (including tricycles) are allowed on bike paths unless otherwise posted.
