Massachusetts e-bike and e-trike laws

✓ Last verifiedVerified Sep 2026Every rule links to the statute or state agency page
In short

Yes: Massachusetts law expressly covers electric 'tricycles', so a Class 1 or Class 2 e-trike (750 watts or less, 20 mph) is treated like a bicycle, with no license, plate or insurance. Ride on roads and bike lanes, and on bike paths unless the town bans it, but never on sidewalks. In state (DCR) parks, only pedal-assist Class 1 trikes may use paved trails 8+ feet wide. Avoid 28-mph Class 3 models, which state law does not recognize as e-bikes.

Does an e-trike count as an e-bike here? Yes.
License
No license, registration or insurance is needed for a Class 1 or 2 e-bike or e-trike; they are excluded from 'motor vehicles'.
Helmet
Riders and passengers 16 and younger must wear a helmet (bicycle rule applied to e-bikes); there's no adult requirement.
Minimum age
State law sets no minimum age for Class 1 or 2 e-bikes (a motorized bicycle requires age 16).
Where you can ride
E-bikes have the same rights and duties as regular bicycles, so you may use public roads (except posted limited-access highways) and bike lanes.
Sidewalks
E-bikes may never be ridden on sidewalks, even though regular bikes sometimes may.

Does an e-trike count as an e-bike?

Yes
“''Electric bicycle'', a bicycle or tricycle equipped with fully operable pedals and an electric motor of 750 watts or less that meets the requirements of a class 1 electric bicycle or a class 2 electric bicycle.”
M.G.L. c. 90, § 1 ↗

How the law sorts e-bikes

State law defines only Class 1 and Class 2 (both 'bicycle or tricycle', 750 W or less, 20 mph). There is NO statutory Class 3. DCR park regulations do define Class 3, but only for use on DCR property.

Outside the e-bike categories
Treated as a motorized bicycle (moped) or motor vehicle/motorcycle - statute unclear for electric.

A 28-mph Class 3 or over-750 W e-bike is not an 'electric bicycle' under state law. The 'motorized bicycle' definition (max 30 mph, 50 cc, automatic transmission) is written for gas engines, so how an electric Class 3 is classified is not settled in statute. If it is a motorized bicycle, you must be 16+ with a license or permit, wear a helmet, not exceed 25 mph, stay off off-street recreational bike paths (bike lanes are OK), and register it with the RMV.

Statutes and sources
What we couldn't confirm from official sources (3)
  • The Class 1/2 definitions and c. 85 § 11B3/4 were enacted through the 2022 transportation bond bill (H.5151), effective Nov. 8, 2022; the session-law chapter number was not confirmed.
  • The RMV treats Class 3 / over-750 W e-bikes as mopeds (motorized bicycles) requiring registration and a license; there is no insurance requirement for mopeds.
  • The DCR regulation text was read from Cornell LII (mass.gov PDF blocked automated access); confirm against the official 302 CMR on mass.gov.

This page explains the law in plain language. It is not legal advice. Cities, counties and park agencies can add their own rules; check posted signs and confirm with your state before you ride.
