Is it an e-bike, a moped or an e-moto?

Federal law

The federal e-bike. A "low-speed electric bicycle" has two or three wheels, working pedals, a motor under 750 watts and a top speed under 20 mph on the motor alone. Federal law treats it as a bicycle: it must meet the bicycle safety rules, and it isn't a motor vehicle. (15 U.S.C. 2085, 16 CFR 1512)

Where you ride is up to the state. Each state and town sets the rules on licences, age, helmets and where you can ride.

Classes 1, 2 and 3 come from state law. They also appear in federal highway funding law (23 U.S.C. 217) and on federal land: National Park Service areas allow them only where the park designates (36 CFR 4.30), and the Forest Service treats e-bikes as motor vehicles on designated routes.

Faster or more powerful. A bike built for public roads, with a VIN and federal safety certification, is a motorcycle. Off-road e-motos and electric dirt bikes are regulated like gas dirt bikes. Pedals don't make them e-bikes.

Batteries. The Consumer Product Safety Commission proposed a lithium-ion battery standard for e-bikes and scooters in June 2026 (UL 2849 and UL 2271). It isn't final yet.

Massachusetts law today

Class 1 and Class 2 e-bikes (since 2022): working pedals, a motor of 750 watts or less, and no motor help above 20 mph. Class 1 is pedal assist only; Class 2 may have a throttle. (M.G.L. c.90 §1)

• Same rights and duties as a bicycle; no licence, registration or plate.
• No minimum age in state law. Helmet required for riders 16 and under.
• Never on sidewalks, anywhere in the state. Roads and bike lanes are fine; bike paths unless the owner of the path bans them; natural-surface trails only where allowed.
• Lights and a rear reflector at night. Bikes must carry a label with the class, top assisted speed and motor wattage, and the speed may not be changed without updating it. (c.85 §11B¾)

Class 3 (pedal assist to 28 mph) isn't defined yet. MassDOT: "Current Massachusetts law does not define 'Class 3 e-bikes'." (MassDOT FAQ) MassDOT treats Class 3 bikes like bicycles; police could treat one as a moped. Many bikes, Velotric included, can be set to 20 mph, which makes them Class 1 or 2.

Mopeds ("motorized bicycles"). Age 16+, driver's licence or permit, RMV registration and plate, helmet, 25 mph limit; bike lanes allowed, off-street bike paths not. (RMV)

Motorized scooters. Licence or permit, 20 mph maximum, no riding between sunset and sunrise, no passengers, helmet.

E-motos and electric dirt bikes are off-highway vehicles: registered with the Massachusetts Environmental Police (not the RMV), helmet at every age, a safety course for riders under 18, and only on private land with permission or on trails marked for off-highway vehicles. Not on public roads, sidewalks, bike lanes or paths. (Off-highway vehicle laws, c.90B)

Road motorcycles need a VIN and federal certification, RMV registration, insurance and a motorcycle licence.

Boston, Brookline and state parkland

Boston. State law defines Class 1 and 2; e-bikes are not allowed on sidewalks anywhere in Massachusetts. Bluebikes e-bikes are Class 1, with assist ending at 18 mph. (City of Boston)

Brookline. No town e-bike rule beyond state law. The town's park rules ban "motorized devices" in public park areas and don't say whether that includes e-bikes. Check posted signs or ask Parks and Open Space. (Brookline park rules)

DCR paths and parkways (Charles River, Emerald Necklace and other state parkland): Class 1 e-bikes may use paved paths 8 feet wide or more; Class 2 and Class 3 are limited to roads and bike lanes. Helmets for riders under 17 on DCR property. (302 CMR 12.12)

What may change (not law yet)

The state's Special Commission on Micromobility reported in early 2026. It recommended speed tiers: Tier 0 up to 20 mph, Tier 1 21–30 mph (which would include Class 3 e-bikes), Tier 2 31–40 mph and Tier 3 over 40 mph. Each tier has its own helmet, age, battery-safety and where-to-ride rules. (MassDOT)

Those rules are in the economic development bill, H.5576. The House and Senate passed different versions in July 2026, and a conference committee has had it since July 30, 2026. The two versions differ on age limits: the House would bar under-16s from Tier 1–3 devices, the Senate under-14s from any powered device and riders 16 and under from Tiers 1–3. Many parts would start January 1, 2028. (H.5576 status)

Until a bill is signed, the rules on the Massachusetts tab apply.
