A Trek E-bike at Goldstream Sports in Goldstream Valley Saturday morning, October 12, 2019. Goldstream Sports sells, rents and demos a variety of E-bikes, which are now allowed for use in National Parks.

Along with its new policy allowing e-bikes in parks nationwide, the National Park Service has issued a strict definition of what constitutes an e-bike. It defines e-bike as a “two- or three-wheeled cycle with fully operable pedals and an electric motor of less than 750 watts (1 horsepower) that provides propulsion assistance.”

As per the federal definition of “low speed electric bicycle,” which is included in the Consumer Product Safety Act, e-bikes that are allowable in national parks must have a maximum speed of no more than 20 mph, when powered solely by their motors.

For use in National Parks, the motor of the e-bike must provide “assistance only when the rider is pedaling” and must cease to provide assistance when the bike reaches a maximum speed of 28 mph.

Denali may issue further regulations or restrictions on the use of e-bikes, so those who intend to use one are encouraged to check the website prior to visiting.
