E-Bike laws in Massachusetts
Current E-Bike Laws in Massachusetts
As of August 10, 2022, the e-bike definition language was signed into law as amendments to the Transportation Bond Bill (H.5151) to include Class 1 and Class 2 definitions for e-bikes. This law went into effect 90 days from signing, on November 8, 2022.
CLASS 1: Bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the e-bike reaches 20 mph.
CLASS 2: Bicycle equipped with a throttle-actuated motor that ceases to provide assistance when the e-bike reaches 20 mph.
E-bike riders are afforded all the rights and privileges related to all bicycle riders, except that e-bikes are not allowed to be ridden on sidewalks.
Class 1 and Class 2 electric bicycles are not considered to be "motorized bicycles" as further defined in MA law, as such are allowed on bikeways and bike paths, however a local jurisdiction may regulate and prohibit their use, but only after a public notice and public hearing.
E-bikes are not allowed on "natural surface" trails (ie. mountain bike trails) unless otherwise permitted by a local jurisdiction.
