The use of electric-assist bicycles (“e-bikes”) has grown rapidly over the last 5 years. Modern e-bikes often look indistinguishable from a “regular” bike but have robust batteries and technology which are capable of sensing when a rider needs a helping hand over a hill, into a headwind, or accelerating from a stop. While e-bikes have existed for years, recent advances in technology have allowed batteries to become smaller, lighter, cheaper, and longer range, enhancing the usefulness, appeal, and affordability of these machines. E-bikes appeal to many types of people but particularly for those who use them as a tool to overcome limited physical fitness, for people running everyday errands who want to carry heavier loads, and for parents transporting children. 

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, with an electric motor of 750 watts or less.
CLASS 2: Bicycle equipped with a throttle-actuated motor that ceases to provide assistance when the e-bike reaches 20 mph, with an electric motor of 750 watts or less.

Note: MassBike will continue to advocate for a Class 3 definition in order to match MA law with federal definitions and statewide regulations set by the Department of Conservation of Recreation.

E-Bikes in Massachusetts Info Sheet


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 no license is required to ride them and they're allowed on bikeways and bike paths. However a local jurisdiction may regulate and prohibit their use on bikeways/bike paths, 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.

The Previous Law

Before the e-bike definition amendment passed in the Transportation Bond Bill, there was no designation with which to regulate e-bikes. However a “motorized bicycle” is defined as having a helper motor with a cylinder capacity not exceeding fifty cubic centimeters, an automatic transmission, and which is capable of a maximum speed of no more than thirty miles per hour. Motorized bicycle riders must be licensed, and are prohibited from off-street pathways.

The lack of a similar designation for e-bike riders left ambiguity in where electric bicycles should be ridden on paths, trails, and sidewalks.

E-Bike Rebates

Thanks to Representative Natalie Blais (1st Franklin), the Transportation Bond Bill included a provision for $1M to establish a state rebate program to offset the cost of e-bikes with $500 rebates to consumers – and $750 rebates for low-income consumers. The bill directs the Department of Energy Resources to evaluate offering electric bicycle rebates at the point of sale through Massachusetts-owned and operated bicycle retailers. This is a bond authorization that still needs to be included in the Capital Improvement Plan (CIP) to be allocated, which is done by the Governor's administration. Typically, the finance teams will begin this work early next year in 2023, with a plan released in late May or early June. Once the funding is included in the CIP, the grant program can be announced.

MassBike is advocating for the ability to apply the rebate retroactively, which is still in discussion.

Interested in e-bike rebates?  The Department of Energy Resources has been hearing from constituents and is compiling all of the comments and outreach they receive around e-bike rebates. The best thing you can do to support Massachusetts E-Bike rebates is to send an email explaining your interest in electric bicycle rebates to DOER’s general email address [email protected]. Please CC [email protected] so that we can keep track of support.

National Legislation

There is a bill in the House of Representatives, Electric Bicycle Incentive Kickstart for the Environment Act or the E-BIKE Act, which would allow a refundable tax credit for 30% of the cost of a qualified electric bicycle. You can see the full bill here: H.R. 1019 - E-Bike Act
