Only Class 1 e-Bikes Allowed on Acadia's Carriage Roads

Graphic for an eBike

Class 1 e-bikes are now allowed where traditional bicycles are allowed in Acadia National Park, consistent with NPS Policy Memorandum 19-01 on Electric Bicycles. The speed limit on carriage roads and Schoodic bike paths has been reduced from 25 mph to 20 mph to ensure the safety of all users.

Island Explorer buses and Bike Express trailers are not transporting eBikes at this time due to load limitations.

All three classes of e-bikes continue to be allowed where motor vehicles are allowed in Acadia National Park:

  • Class 1 e-bikes are equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 20 mph.
  • Class 2 e-bikes are electric bicycles equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 mph. Class 2 e-bikes continue to be prohibited on the carriage roads and Schoodic bike paths because they can be powered by a throttle that does not require the rider to pedal.
  • Class 3 e-bikes are electric bicycles equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 28 mph. Class 3 e-bikes continue to be prohibited on the carriage roads and Schoodic bike paths because of heightened safety risks in the context of a gravel surface shared by high concentrations of slower-moving pedestrians and equestrians, including horse-drawn carriages, traditional bicyclists, and runners and because of the potential for exceeding the speed limit.


The NPS will monitor the use of e-bikes on the carriage roads and Schoodic bike paths to document and assess potential impacts on the visitor experience (including safety concerns and user conflicts), resources, and facilities. The NPS reserves the right to limit, restrict, or impose other conditions on e-bike use in the future after taking into consideration public health and safety, natural and cultural resource protection, and other management activities and objectives.

The NPS reminds bicyclists on the carriage roads and Schoodic bike paths to adhere to the following rules and safety advisories:

  • Bicyclists yield to all users.
  • Slow down. Speeding can be hazardous.
  • Be prepared to stop. Sudden stops are dangerous on loose gravel.
  • Stay to the right. Give a clear warning before passing on the left.
  • Move to the side when stopped.
  • Maine state law requires that helmets be worn by all bicyclists under age 16.
