Are e-bikes allowed in Sawtooth National Forest?

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. In Sawtooth National Forest, Class 1 access is recorded on 318 trail segments; Class 2 and 3 on 318 and 318 respectively.

Does an e-bike count as a mountain bike on Sawtooth National Forest trails?

No. Under USFS policy an e-bike of any class is a motor vehicle, even Class 1 pedal-assist. A trail being open to conventional bikes does not by itself permit e-bikes — the trail must carry an e-bike or motorized designation.

When are bikes open in Sawtooth National Forest?

Most bike-designated trails in Sawtooth National Forest carry a Year-round season window in the USFS data; higher-elevation trails open later as snow clears. Always confirm current conditions with the ranger district.
