On National Forest System land, e-bikes are legally motor vehicles. Under U.S. Forest Service policy (36 CFR 212; FSM 7700), an e-bike of any class may be ridden only on routes that are designated for motor-vehicle use or specifically designated for e-bike use — not on every trail where a conventional (non-motorized) mountain bike is allowed.
