Electric Bike Classes Explained: 1, 2 and 3 (2026)

The Three E-Bike Classes at a Glance

Most US states sort electric bikes into three classes based on how the motor helps and at what speed it stops. The class decides where you can ride, and sometimes who can ride.

The motor's limit isn't your speed limit: you can pedal faster than 20 or 28 mph, but the motor stops helping. Local speed limits still apply.

Class 1 E-Bikes

A Class 1 e-bike only helps when you pedal, and the assist cuts out at 20 mph. There's no throttle. Because Class 1 bikes ride most like regular bikes, they're allowed in the most places, including many bike paths and a growing number of mountain bike trails. Most electric mountain bikes are Class 1.

Best for: trail riding, riders who want maximum access, and anyone who wants an e-bike that feels like a regular bike.

Class 2 E-Bikes

A Class 2 e-bike has a throttle that can move the bike without pedaling, up to 20 mph, and usually pedal-assist as well. The throttle is handy for getting moving from a stop, for riders with limited leg strength, and for resting on long rides. Many fat tire, folding and cruiser e-bikes are Class 2.

Best for: casual riding, riders with knee or joint issues, and anyone who wants help starting from a stop. Some trails and paths that welcome Class 1 bikes don't allow throttles.

Class 3 E-Bikes

A Class 3 e-bike gives pedal-assist up to 28 mph and must have a speedometer. States differ on throttles: some treat Class 3 as pedal-assist only, while others allow a throttle limited to 20 mph. Class 3 bikes are popular for longer commutes on roads.

Because of the higher speed, many states restrict Class 3 bikes from multi-use paths and trails, set a minimum rider age (often 16) and require helmets.

Best for: road commuters covering longer distances who want to keep up with traffic in bike lanes. See the fastest electric bikes.

Federal Law vs State Classes

These are two different things:

• Federal definition (consumer product law): under 15 U.S.C. 2085, a "low-speed electric bicycle" has fully operable pedals, an electric motor of less than 750 watts and a top speed of less than 20 mph on motor power alone with a 170-pound rider. This governs how e-bikes are regulated as consumer products, under the Consumer Product Safety Commission, rather than as motor vehicles.
• The three-class system (state traffic law): a model law promoted by the advocacy group PeopleForBikes that states adopt to decide where and how e-bikes can be ridden. It isn't a federal law. PeopleForBikes reported that 40 states had adopted the system as of April 2023, often with local variations.

Rules where you live can differ from the summary here. Some states add their own categories or tweaks, and cities can set their own rules for paths and parks. Always check your state and local rules.

Class Labels

Under the model law, manufacturers must attach a label to each e-bike showing its class, top assisted speed and motor wattage. If you modify a bike so its speed or power no longer matches the label, it may no longer count as that class.

Where Each Class Can Ride

"Usually" means typical of states using the three-class model. Local rules decide; look for signs at trailheads and check with the land manager.

Federal Lands and National Parks

• National parks: a National Park Service rule that took effect in December 2020 generally allows e-bikes where regular bikes are allowed, with each park's superintendent setting the details. E-bikes are not allowed in designated wilderness. Some parks restrict certain classes; for example, Grand Canyon has been reported to limit Class 2 throttle use to roads.
• Interior Department lands: a 2019 order directed agencies such as the Bureau of Land Management to treat e-bikes more like bikes than motor vehicles, subject to local decisions.
• National forests: the US Forest Service generally treats e-bikes as motor vehicles, so they're limited to roads and trails open to motorized use unless a forest says otherwise.

What Isn't an E-Bike

Bikes with motors over 750 watts, motor-only speeds above the class limits, or no working pedals generally don't qualify as e-bikes. Depending on the state, they may be treated as mopeds, motorcycles or off-highway vehicles, which can mean registration, a license, insurance or an off-road-only restriction.

• "Class 4" doesn't exist in the three-class system. Sellers sometimes use the term for high-power bikes, but it has no legal standing as an e-bike class.
• Electric motorbikes and electric dirt bikes such as Sur-Ron-style bikes are motor vehicles, not e-bikes. See electric dirt bikes.
• "Unlockable" bikes: some bikes can be switched into higher-power or higher-speed off-road modes. Using those modes on public roads or paths can break the law.

E-Bike Rules Outside the US

Throttles, ages and helmet rules vary within these regions, so check local rules.

How to Choose a Class

Safety Tips for Every Class

• Wear a helmet even where it isn't required; see bike helmets.
• Slow down on shared paths and announce yourself when passing.
• Remember that drivers and pedestrians may misjudge how fast you're going.
• Choose bikes and batteries certified to safety standards such as UL 2849; see our battery guide.
