E-bike access by class across Colorado
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.
| E-bike class | Definition | Trail segments with access | Miles |
|---|---|---|---|
| Class 1 designated | Pedal-assist only, motor cuts out at 20 mph, no throttle. | 1,493 | 3,611 mi |
| Class 2 designated | Throttle-assist up to 20 mph (can propel without pedaling). | 1,487 | 3,601 mi |
| Class 3 designated | Pedal-assist up to 28 mph, no throttle. | 1,487 | 3,601 mi |

Frequently asked questions
- Are e-bikes allowed in Colorado national forests?
- Only where designated. 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 Colorado, USFS data records Class 1 access on 1,493 trail segments and Class 2/3 on far fewer. Check the specific forest before you ride.
- What's the difference between Class 1, 2 and 3 e-bikes on national forest trails?
- Class 1: Pedal-assist only, motor cuts out at 20 mph, no throttle. Class 2: Throttle-assist up to 20 mph (can propel without pedaling). Class 3: Pedal-assist up to 28 mph, no throttle. On Forest Service land all three are motor vehicles regardless of class, so access depends on the trail's motorized designation.
- Can I ride a Class 2 (throttle) e-bike on Colorado forest trails?
- Rarely. Class 2 access is recorded on only 1,487 segments statewide — most non-motorized singletrack that allows Class 1 still excludes throttle-assist Class 2 and 3 e-bikes. Verify with the managing ranger district.
