Maine uses three classes of electric bicycle. Class 1 is pedal assist ending at 20 mph; Class 2 may propel without pedaling but may not propel the bicycle at 20 mph; and Class 3 is pedal assist ending at 28 mph.Maine Legislature — 29-A M.R.S. § 101 Spot an error? →

The short answer
A qualifying electric bicycle is exempt from Maine Title 29-A provisions on financial responsibility, driver's licenses, registration, and license plates. Riders under 16 may not operate Class 2 or Class 3, every e-bike operator or passenger under 16 must wear a helmet, and Class 3 and natural-surface bicycle paths have tighter access rules.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
01 / Categories
Pedal assist · 20 mph
It must have 2 or 3 wheels, fully operable pedals, an electric motor of less than 750 watts, and the motor behavior and assisted-speed limit of Class 1, 2, or 3.Maine Legislature — 29-A M.R.S. § 101 Spot an error? →
The motor assists only while the rider pedals and ceases assistance when the bicycle reaches 20 mph.Maine Legislature — 29-A M.R.S. § 101 Spot an error? →
Motor-only · below 20 mph
The motor may be used exclusively to propel the bicycle but may not be capable of propelling it at a speed of 20 mph.Maine Legislature — 29-A M.R.S. § 101 Spot an error? →
Pedal assist · 28 mph

02 / Class consequences
| Class | Motor behavior | Assisted limit | Core consequence |
|---|---|---|---|
| Class 1 | Pedal assist only | 20 mph | No Title 29-A driver's-license, registration, license-plate, or financial-responsibility requirement. An operator or passenger under 16 must wear a helmet. Class 1 may go wherever bicycles are permitted, including bicycle paths, unless the path authority prohibits it; the natural-surface path restriction still applies.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? → |
| Class 2 | May propel without pedaling | Below 20 mph | No Title 29-A driver's-license, registration, license-plate, or financial-responsibility requirement. The operator must be at least 16; a passenger under 16 is allowed only on a bicycle designed for passengers and must wear a helmet. Class 2 may go wherever bicycles are permitted, including bicycle paths, unless the path authority prohibits it; the natural-surface path restriction still applies.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? → |
| Class 3 | Pedal assist only | 28 mph | No Title 29-A driver's-license, registration, license-plate, or financial-responsibility requirement. The operator must be at least 16, the bicycle needs a speedometer, and a passenger under 16 is allowed only on a bicycle designed for passengers and must wear a helmet. A Class 3 bicycle path must be within a highway or roadway or specifically authorized; the natural-surface path restriction also applies.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? → |
Classification unclear: a device outside Maine's definition—for example, a 750-watt motor, no fully operable pedals, throttle propulsion capable of 20 mph, or assistance beyond the class limits—is not a qualifying electric bicycle. The cited sources do not establish one replacement category or one access answer for every such device.Maine Legislature — 29-A M.R.S. § 101· Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
03 / Rider requirements
Adult helmet answer unclear from the cited sources alone: Maine's e-bike paragraph expressly requires helmets for operators and passengers under 16, but the cited provisions do not separately state an all-clear rule for riders age 16 or older.Maine Legislature — 29-A M.R.S. § 2063· Maine Legislature — 29-A M.R.S. § 2322 Spot an error? →
04 / Where you can ride
For § 2063, “bicycle” expressly includes an electric bicycle. A person riding a bicycle on a way has the rights and duties applicable to a vehicle operator, subject to bicycle-specific rules, and may travel on paved shoulders. Riders traveling slower than traffic generally keep to the right except in the listed situations.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
Bike-lane scope is unclear: MaineDOT says bicyclists may use bike lanes and need not use them, while § 2063 includes electric bicycles in “bicycle” for that section. Neither cited source separately states the result for every e-bike class in an on-road bicycle lane.Maine Legislature — 29-A M.R.S. § 2063· MaineDOT — bicycle and pedestrian laws Spot an error? →
Sidewalk access is unclear for e-bikes: MaineDOT says bicycle sidewalk riding is allowed in most cases unless a municipal ordinance prohibits it, but the cited guidance does not separately address electric-bicycle classes. Check the local ordinance rather than assuming statewide permission.Maine Legislature — 29-A M.R.S. § 2063· MaineDOT — bicycle and pedestrian laws Spot an error? →
Yes, wherever bicycles are permitted, including bicycle and multi-use paths, unless the municipality, local authority, or public agency with jurisdiction prohibits Class 1 or Class 2 on that path. The separate natural-surface restriction still applies.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
Only if the bicycle path is within a highway or roadway or the municipality, local authority, or public agency with jurisdiction has authorized Class 3 operation. The separate natural-surface restriction still applies.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
Not by default when significant portions of a nonmotorized bicycle path have a natural surface, including gravel, stones, or wooden bridging. Operation is allowed only if the municipality, local authority, or public agency with jurisdiction authorizes it.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
A municipality, local authority, or public agency with jurisdiction may prohibit Class 1 or Class 2 on its bicycle path, authorize Class 3 there, and authorize e-bikes on covered natural-surface paths. Private-way and private-property owners retain authority to restrict or allow electric bicycles on their property.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
05 / Common questions
Driver's license, Maine Title 29-A registration, and license plate: no—§ 2063 expressly exempts them. Insurance remains amber because the same sentence says “financial responsibility” rather than expressly answering every insurance or private-policy question.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
A rider under 16 may not operate Class 2 or Class 3. Class 1 remains unclear because the cited sources state no numerical minimum age for that class. Every operator or passenger under 16 must wear a properly fitted and fastened bicycle helmet; a passenger under 16 on Class 2 or Class 3 is allowed only if the bicycle is designed for passengers.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
Class 1 and 2 may use bicycle paths where bicycles are allowed unless the path authority prohibits them. Class 3 needs a path within a highway or roadway or specific authorization. Every class needs specific authorization on a nonmotorized path with significant natural-surface portions.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
Yes, as Class 2, if it otherwise meets the electric-bicycle definition and its motor is not capable of propelling the bicycle at a speed of 20 mph. A throttle-capable device at 20 mph or above does not fit Maine's Class 2 definition, and its replacement category is unclear from the cited sources.Maine Legislature — 29-A M.R.S. § 101 Spot an error? →
General e-bike penalty unclear: § 2063's stated $25-to-$250 traffic-infraction fine lists violations of subsections 2, 3, 3-A, 4, 6, and 9 through 13, but does not list the electric-bicycle rules in subsection 14. The cited sources do not state one general penalty for every subsection 14 violation.Maine Legislature — 29-A M.R.S. § 2063 Spot an error? →
