Idaho eBike rules snapshot
Idaho defines three classes of electric-assisted bicycle in Idaho Code § 49-106. The bike needs fully operable pedals and a motor under 750 watts. A Class 1 motor helps only while you pedal and stops helping at 20 mph. A Class 2 motor may drive the bike by itself and cannot help at 20 mph. A Class 3 motor helps only while you pedal and stops helping at 28 mph. Under § 49-727, makers and distributors must label each bike with its class, top assisted speed, and motor wattage.
Under § 49-725, an electric-assisted bicycle carries the safety requirements of a bicycle, and its rider has a bicyclist's rights and duties. Under § 49-726, the bike is outside the Title 49 rules on driver's licenses, titles, registration, license plates, and financial responsibility, and counts as a motor vehicle only as far as 23 U.S.C. 154 requires. Section 49-714, amended in 2026, gives riders the rights and duties of a driver and requires due care, and § 49-615 requires drivers to use due care around them. Under § 49-729, a rider's violation of those chapters is an infraction.
Sections 49-725 and 49-728 let an electric-assisted bicycle go anywhere a bicycle may go, multiuse paths included, unless a local ordinance excludes it or the public agency in charge posts a sign after putting the change on a governing-board agenda. Each city, county, park, and land manager therefore sets its own path rules. We found no statewide eBike helmet rule and no minimum operator age. The helmet statute, § 49-666, covers riders under 18 on motorcycles, motorbikes, UTVs, and ATVs, and § 49-114 says a motorbike does not include an electric-assisted bicycle. Read our Idaho eBike laws guide, then the sign at the trailhead.
The Idaho Department of Parks and Recreation says on its biking page that Class 1 and Class 2 eBikes are allowed in Idaho state parks and on department-administered trails and paths, except the Lewiston Levee Parkway. That page does not address Class 3, and the department's Ashton to Tetonia Trail page says Class 3 eBikes are not permitted there, so ask the park about Class 3 before you ride.
Federal land follows different rules. The Forest Service manages eBikes as motor vehicles under its travel management rules, so a national forest trail is open to them only where the forest has designated that use. Ridge to Rivers says the same for the federal trails near Boise. National Park Service units and wildlife refuges publish their own eBike rules, and we cite them on the routes where we found them.
The Sawtooth National Recreation Area, part of the Forest Service, says eBikes are not allowed on the Stanley to Redfish Trail. The Forest Service treats eBikes as motor vehicles under its travel management rules.
