Electric Bicycles (E-Bike)

Electric-assist bicycles, or e-bikes, have become increasingly popular across Massachusetts in recent years. With their rising popularity, it is important for all riders to understand that e-bikes are subject to specific rules under Massachusetts law. Riders must follow the same traffic laws as motor vehicles and traditional bicycles, including obeying traffic signals, yielding to pedestrians, and riding safely and predictably.

Are you riding OVER 20 MPH? You’re riding a MOTORIZED BIKE !

You must have a driver’s license, registration and moped license plate.

Any e-bike exceeding the power or speed thresholds of Class 1 or 2 or has been modified is considered a “motorized bicycle” under M.G.L. c. 90, § 1. Violators will be towed and face criminal charges.

E-Bike Classifications Under Massachusetts Law

CLASS 1: A low-speed electric bicycle equipped with a motor that provides assistance only when the rider is pedaling and ceases to provide assistance when the bicycle reaches 20 miles per hour.
CLASS 2: A low-speed ed electric bicycle equipped with a throttle-actuated motor that can propel the bicycle without pedaling but ceases to provide assistance at 20 miles per hour.
MOTORIZED BIKE: The law does not define Class 3 e-bikes, a term commonly used in other jurisdictions and the bicycle industry to refer to pedal-assist e-bikes that operate up to 28 mph with a speedometer. Since Massachusetts does not codify Class 3, any any e-bike e-bike exceeding the power or speed thresholds of Class 1 or 2 may instead be considered a "motorized bicycle" under G.L. c. 90, § 1, which is subject to registration, license, and helmet requirements.
- Motorized bicycles MAY be operated on public roads and bikes lanes
- Motorized bicycles MAY NOT be operated on sidewalks

Best Practices for E-Bike Riders

Stay Alert

Keep your eyes and ears open. Be aware of your surroundings and watch for cars, pedestrians, and other cyclists. Avoid wearing headphones or earbuds while riding

Ride at a Safe

Adjust your speed based on the environment. Slow down in busy areas, near schools, on shared-use paths, or when approaching pedestrians.

Follow Traffic Laws

E-Bikes must follow the same traffic rules as regular bicycles and motor vehicles. This includes stopping at red lights and stop signs, yielding when required, and using hand signals.

Wear Safety Gear

A properly fitted helmet is strongly recommended for all riders. At night, your e-bike MUST have a white front light and a red read light or reflector to ensure visibility

Respect Town Property and Trail Guidelines

E-bike use is limited or prohibited on some town-owned lands, including trails, parks, fields, school grounds, and conservation areas. Always yield to pedestrians and check posted signs or rules before riding.

Be Courteous

When passing pedestrians or slower riders, give a verbal warning such as “on your left” and pass safely. Avoid weaving through crowds or groups.

Handle Batteries with Care

Lithium-ion batteries can pose a fire hazard if damaged or improperly charged. Use only manufacturer approved chargers, avoid charging overnight, and store batteries in a cool, dry place. Never charge a damaged battery.

Know Where You Can Ride and Park

Do not block sidewalks, entrances, or access points. Park e-bikes upright in bike rakes or designated areas when possible.

Electric Scooters (E-Scooters)

Electric scooters are not considered e-bikes. While there are some low-speed toy versions marketed for children, all motorized e-scooters fall under the definition of motorized scooters in Massachusetts General Law c.90 §1. A motorized scooter is defined as an 2 wheeled tandem or 3 wheeled device, that has handlebars, designed to be stood or sat upon by the operator, powered by an electric or gas powered motor that s capable of propelling the device with or without human propulsion. This definition includes motorcycles, electric bicycles, motorized bicycles, and three wheeled motorized wheelchairs.
