For WA DNR, and Gifford Pinchot where I spend most of my backcountry time...

There is some movement for class 1 ebikes to be allowed on trails open to MTBs but there is stiff resistance from organized hiker and horsemen orgs.
New guidelines are making it tricky to figure out where e-bikes are allowed. Here's what we know right now.

A private forest I frequent allows non-motorized bikes but not ebikes. The tree farms I'm familiar with allow bikes with a non-motorized permit, but ebikes need a much more expensive motorized permit.
IMHO ebike encounters with hikers, MTBs, and especially horses on trails with a silent ebike capable of 20 mph just seem very hazardous. Feel free to enlighten me.
