What Is an E-Bike?

Under Massachusetts law, an electric bicycle is a bicycle equipped with fully operable pedals and an electric motor of 750 watts or less. Massachusetts currently recognizes two classes of e-bikes:

Class 1 E-Bikes

Class 1 e-bikes provide assistance only when the rider is pedaling (“pedal assist”) and stop providing assistance at 20 mph.

Class 2 E-Bikes

Class 2 e-bikes may include a throttle that can propel the bicycle without pedaling, but the motor assistance also stops at 20 mph.

Massachusetts does not currently recognize “Class 3” e-bikes in state law. Higher-speed e-bikes may instead be classified as motorized bicycles, e-motos or mopeds depending on their speed and power.

E-Bikes vs. Motor Bikes

A common point of confusion is the difference between an e-bike and a motor bike or motorcycle.

E-Bikes

• Have fully operable pedals
• Use a small electric motor for assistance
• Are limited to 20 mph motor assistance
• Typically weigh and operate similarly to traditional bicycles
• Do not require registration or a driver’s license in Massachusetts for Class 1 and Class 2 models

Motor Bikes / Mopeds / Motorcycles (e-Motos)

Motor bikes, mopeds, and motorcycles are motor vehicles. They may:

• Operate without pedaling
• Travel at significantly higher speeds
• Require registration, licensing, and insurance
• Be prohibited from bike paths and rail trails

Some electric-powered two-wheel vehicles may resemble bicycles but exceed Massachusetts e-bike limits for speed or power. In those cases, they may legally be considered motorized vehicles rather than bicycles.

What Is Allowed on the Cape Cod Rail Trail?

Under Massachusetts law, Class 1 and Class 2 e-bikes generally have the same rights and responsibilities as traditional bicycles and are permitted on paved bikeways and shared-use paths unless a local jurisdiction specifically restricts them.

The Massachusetts Department of Conservation and Recreation (DCR) currently allows Class 1 e-bikes on many shared-use trails.

Allowed

• Traditional bicycles
• Class 1 e-bikes
• Many Class 2 e-bikes, where permitted
• Pedestrian and recreational trail use consistent with posted regulations

Not Allowed

• Motorcycles
• Gas-powered bikes
• Mopeds
• High-speed motorized vehicles
• Off-road motorcycles or dirt bikes

Trail users should always:

• Yield to pedestrians
• Ride at safe speeds
• Announce when passing
• Follow posted trail signage
• Wear helmets, required for riders under age 16

Recent Massachusetts E-Bike Legislation

Massachusetts updated its e-bike laws in 2022 by formally defining Class 1 and Class 2 electric bicycles in state law. These changes clarified that qualifying e-bikes are treated differently from motorized bicycles (e-Motos) and are generally permitted where traditional bicycles are allowed.

In May 2026, Governor Maura Healey introduced the proposed “Ride Safe Act,” legislation intended to strengthen public safety and establish clearer statewide regulations for e-bikes, mopeds, scooters, and other micromobility devices. The proposal was developed in response to increasing use of these vehicles and growing concerns about safety on roads, sidewalks, bike lanes, and shared-use trails.

The proposed legislation would create a new speed-based classification system for micromobility devices:

• Tier 0: Devices with a maximum assisted speed of 20 mph or less, including traditional bicycles, many Class 1 and Class 2 e-bikes, and lower-speed scooters.
• Tier 1: Devices capable of speeds between 21–30 mph, including many Class 3 e-bikes.
• Tier 2 and Tier 3: Higher-speed electric motorbikes and scooters that would face additional regulations and roadway restrictions.

Under the proposal, lower-speed e-bikes would generally continue to have access to bike lanes, rail trails, and shared-use paths, while higher-speed devices could face stricter rules involving helmets, age requirements, registration, insurance, and roadway use. The legislation also seeks to better distinguish between electric bicycles and higher-powered electric motorbikes (e-Motos) that more closely resemble mopeds or motorcycles.

The Ride Safe Act is currently proposed legislation and has not yet become law. As state regulations continue to evolve, trail users should stay informed and always follow posted trail rules and safety guidance. We’ll do our best to keep you updated on this page and our facebook group.

Ride Responsibly!

The Cape Cod Rail Trail is a shared recreational resource enjoyed by walkers, runners, cyclists, families, and visitors from across the region. Whether riding a traditional bicycle or an e-bike, courteous and safe riding helps ensure the trail remains enjoyable for everyone.
