Frequently asked questions
- Are e-bikes allowed in Beaverhead-Deerlodge 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 Beaverhead-Deerlodge National Forest, Class 1 access is recorded on 1 trail segments; Class 2 and 3 on 1 and 1 respectively.
- Does an e-bike count as a mountain bike on Beaverhead-Deerlodge 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.

- Most bike-designated trails in Beaverhead-Deerlodge 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.
