Maine
Last updated
Maine adopted the three-class e-bike framework with Maine LD 1222, effective September 19, 2019, and treats a compliant e-bike like a regular bicycle: no license, no registration, no insurance, and no title. Compliant means fully operable pedals and a motor of less than 750 watts; go bigger and it stops being an e-bike in the eyes of the state. Class 1 assists only while pedaling up to 20 mph and is legal for all ages, Class 2 may run on throttle alone up to 20 mph, and Class 3 assists while pedaling up to 28 mph with a required speedometer and classification label (29-A M.R.S. 2063). No one under 16 may operate a Class 2 or Class 3, though they may ride as a passenger, and every operator and passenger under 16 wears a helmet on any class; adults face no statewide helmet mandate.
All three classes ride roads and bike lanes wherever bicycles ride. On shared-use paths, Class 1 and Class 2 are allowed where bicycles are unless a local authority bars them, while Class 3 is barred from bike paths unless the path is within a roadway or specifically authorized. The trail rules change by land manager: Acadia allows Class 1 only on its carriage roads and Schoodic bike paths at a 20 mph limit, the Eastern Trail permits Class 1 and Class 2 but not Class 3, the motorized Down East Sunrise Trail welcomes e-bikes, and Baxter State Park bans them outright. Over 750 watts or with the limiter removed, it is regulated as a moped or motor vehicle instead. Our Maine bicycle and e-bike insurance page pairs these rules with the state's best rides, riding season, and events. The full breakdown is below.
Maine E-bike Laws
Three classes, no paperwork, and trail rules that change from Acadia to Baxter. Here is where Maine stands on e-bikes.
Maine adopted the three-class e-bike framework in 2019, and it treats a compliant e-bike like a regular bicycle: no license, no registration, no insurance, no title. Compliant means fully operable pedals and a motor of less than 750 watts; go bigger and it stops being an e-bike in the eyes of the state.
The motor assists only while you pedal and cuts off at 20 mph; legal for all ages.
A throttle can propel the bike without pedaling, but assistance still ends at 20 mph; riders must be at least 16.
Pedal assist runs up to 28 mph; Maine requires a speedometer and a classification label (29-A M.R.S. 2063).
Operators are exempt from the license, registration, and financial-responsibility rules that apply to motorists (29-A M.R.S. 2063(14)).
Compliant e-bikes are not motor vehicles, so there is no title, plate, or BMV visit.
Maine mandates no coverage for any e-bike class, which leaves the financial risk on you.
No one under 16 may operate a Class 2 or Class 3, though they may ride as a passenger; there is no age floor for Class 1 (29-A M.R.S. 2063(14)).
Every operator and passenger under 16 wears a helmet on any class (29-A M.R.S. 2063); adults face no statewide helmet mandate on any e-bike.
