Idaho E-Bikes and Electric Scooters: What Riders Need

First, what counts as an e-bike in Idaho

The class system arrived in 2019 (Session Laws chapter 84) and lives in Idaho Code 49-106. To count, the bike needs pedals that really work, a motor rated below 750 watts, and a fit with one of three classes. Class 1 is pedal assist that cuts out at 20 mph. Class 2 adds a throttle, so it can move with no pedaling, but it also tops out at 20. Class 3 is pedal assist again, with the help lasting until 28 mph.

Look for a sticker on the frame. Since September 1, 2019, Idaho Code 49-727 has made makers and distributors fix a permanent one listing the class, the assisted top speed and the motor's watts. The statute's history notes for sections 49-725 through 49-729 show nobody has changed the e-bike rules since they were written.

Before you buy: paperwork

Idaho Code 49-726 takes e-bikes out of the license requirement in 49-301, and neither bike nor rider is subject to Idaho's financial responsibility, title, registration or plate rules. Buy it and ride it the same afternoon.

The only time Idaho calls an e-bike a motor vehicle is where federal highway funding law (23 U.S.C. 154) insists on it. If you break a traffic or bicycle rule while riding one, Idaho Code 49-729 makes it an infraction, the same level as an ordinary ticket.

Before you buy for a child: age and helmets

State law gives no age floor for any of the three classes, and Idaho has never passed a helmet law for bicycles or e-bikes. The helmet statute that does exist, Idaho Code 49-666, covers riders under 18 on ATVs, UTVs, motorbikes and motorcycles. E-bikes are not on that list.

Some cities fill the gap. Inside Boise city limits, the city says a rider younger than 18 is legally required to wear a helmet on a bicycle or any e-mobility device. Towns differ, so look up your own city code before a younger teen gets a throttle bike.

Worked example: a 12 year old in Meridian wants a Class 2 throttle bike. State law allows it at any age. Check Meridian's code, set a helmet rule at home, and consider a Class 1 bike for a rider that young.

On the road: where you can ride

Legally you ride as a cyclist: Idaho Code 49-725 gives e-bike riders the same rights and duties, and 49-728 opens every place bicycles may go, multiuse paths included. To keep e-bikes out, a city, county or path agency needs an ordinance, or signs put up only after the question went on a governing board's agenda.

Sidewalks and crosswalks come with manners spelled out in Idaho Code 49-721: walkers get the right of way, you make a sound before you pass them, and where a sign or signal forbids riding, you walk the bike. Cities can add stricter rules.

Idaho is famous for letting cyclists treat a stop sign as a yield, and Idaho Code 49-720 names e-bikes in that part: slow down, give way, then carry on if it is clear. Red lights are a different paragraph. The permission to go through a red after stopping and checking applies to pedal bikes and other human-powered vehicles only, so on an e-bike, wait for green.

If it is really a moped or motor-driven cycle

Once the motor reaches 750 watts, Idaho stops calling it an e-bike. Idaho Code 49-114 describes a moped as a slow motor-driven cycle: wheels smaller than 20 inches and a top speed no higher than 30 mph. The electric version has an automatic transmission, no pedals and less than two gross brake horsepower, and has to satisfy the federal safety rules for motor-driven cycles.

Mopeds skip the title and the motorcycle endorsement. They are still motor vehicles, though, so whoever rides one must hold a driver's license (Idaho Code 49-301). Step up to a motor-driven cycle of no more than five brake horsepower and you need both a title and the endorsement. Boise cautions that lots of high-powered electric motorcycles, or e-motos, can never be titled, insured or licensed in Idaho, which means they are not legal on public streets at all.

Electric scooters

Stand-up scooters do not get their own section of state law. The closest definition is for an electric personal assistive mobility device: a two-wheeled, self-balancing machine limited to 15 mph. On a sidewalk, its rider is treated like a pedestrian under 49-721.

So cities write most scooter rules. Boise legalized e-scooters and e-bikes by ordinance in 2018 and, in July 2023, made Lime its one shared scooter and bike company. Boise lets scooter riders use bike lanes, streets, crosswalks and sidewalks, plus the Greenbelt, whose city-managed paths run 29 miles.

If you ride in Boise

Under Boise City Code, bikes that stop helping at 20 mph and have motors no bigger than 750 watts (in practice, Classes 1 and 2) may ride on the Greenbelt, in bike lanes, on streets, and on sidewalks and crosswalks. The faster Class 3 bikes are banned from the Greenbelt and from sidewalks and crosswalks. One of the city's pages adds bike lanes to the Class 3 ban, so read the ordinance as it stands today.

Boise treats anything over 750 watts, or able to pass 28 mph, as an e-moto. That means a license with a motorcycle endorsement, plus title, plate and insurance, and no riding on the Greenbelt, in bike lanes or on sidewalks. For off-road riding, the Ridge to Rivers system opens roughly 52 miles of primitive roads and motorized trails to both e-bikes and e-motos.

Renting a Lime? Downtown and at Boise State you must leave it in a marked parking zone, and blocking a doorway, a ramp or a bus stop can earn a fine. Riding any of these devices recklessly can be charged as a misdemeanor.
