State guide
Massachusetts
Massachusetts currently defines "electric bicycle" to include only class 1 and class 2 e-bikes in Chapter 90, and a separate 2022 law gave e-bikes most bicycle rights and duties while banning sidewalk riding. State law lets municipalities, local authorities, and state agencies regulate e-bikes on bike paths and bikeways after public notice and hearing, and it bars e-bikes from natural-surface nonmotorized trails unless a jurisdiction affirmatively allows them.

- Three-class system
- Massachusetts has not adopted the full three-class system; Chapter 90, Section 1 defines only class 1 and class 2 electric bicycles, and state FAQ pages say current law does not define class 3 e-bikes.
- Minimum age
- No minimum rider age for class 1 or class 2 was located in the state statutes or agency pages searched; class 3 is not defined in current Massachusetts law.
- Helmet rule
- Because e-bike riders are subject to bicycle duties, riders or passengers age 16 or younger must wear a helmet on a public way, bicycle path, or other public right-of-way.
- Where e-bikes may ride
- State law bars e-bikes from sidewalks; they otherwise get bicycle rights and may use bike paths and bikeways unless a municipality, local authority, or state agency regulates or prohibits them after notice and hearing; natural-surface nonmotorized trails are closed unless the jurisdiction allows them.
- License or registration
- Low-speed electric bicycles are neither required nor authorized to be registered, and the operator is not required to have a license or learner's permit; no separate statewide insurance requirement for e-bikes was located on the official pages searched.
- Law
- M.G.L. c. 90, § 1; M.G.L. c. 85, §§ 11B, 11B1/2, 11B3/4; Acts of 2022, c. 176; 540 CMR 2.00.

What to do next
- If your bike assists above 20 mph, do not assume Massachusetts treats it as an e-bike; current state law only defines class 1 and class 2.
- Before using a local path or trail, check the city, town, or agency rules because Massachusetts expressly allows local restrictions after notice and hearing.
- If you are 16 or younger, wear a helmet on public ways, bike paths, and other public rights-of-way.
