See my exchange in another thread. Depends on who manages the land the trails are on. National Forest doesn’t allow them, but rangers don’t enforce it. National Wildlife Refuge allows them. County open space where I ride only bans gas powered vehicles. Bans of “motorized” vehicles enacted decades ago were intended to keep loud, polluting, fast, and heavy dirt bikes off trails. Electric motors that top out at under 20mph have been swept into this. Eventually, like mountain bikes, people will realize the bans make no sense and allow them.
