The National Park Service, as part of a directive by the Trump administration in 2019, allows e-bikes on all trails in its 423 national parks where traditional bikes are allowed. This is being challenged in a lawsuit by the Public Employees for Environmental Responsibility and a coalition of conservation groups who seek to block e-bike access.
Individual park superintendents can decide whether or not to permit e-bikes on trails. At Point Reyes National Seashore, for instance, e-bike usage is limited to Class I bikes — Class 2 and Class 3 e-bikes are prohibited. At Yosemite National Park, no bicycles, including e-bikes, are permitted on off-road surfaces. But Sequoia National Park offers more e-bike riding opportunities.
