Are e-bikes allowed on mountain bike trails?

It depends on the land manager. Forest Service non-motorized trails generally do not allow them, Interior agencies such as the BLM can allow Class 1 e-bikes trail by trail, and state and local rules vary. Always check the specific trail.

Can you ride an e-bike in national forests?

On roads and trails open to motor vehicles, generally yes. The Forest Service treats e-bikes as motor vehicles, so they are not allowed on non-motorized trails unless specifically designated.

Can you ride an e-bike in national parks?

Only where the park has decided to allow them, usually on roads and some trails open to regular bicycles. Wilderness areas are closed to all bicycles.

What class of e-bike is allowed on trails?

Where e-bikes are allowed on mountain bike trails, it is usually Class 1 only: pedal assist up to 20 mph, no throttle.

Where can you ride an e-MTB in the US? Trail rules explained

The short answer

There is no single US rule for e-MTBs on trails. Access depends on who manages the land, and the main split is between the Forest Service and the Department of the Interior. Where e-bikes are allowed on mountain bike trails, it is almost always Class 1 only: pedal assist up to 20 mph, no throttle. Before you ride anywhere, check that specific trail system.

This is a general guide, not legal advice. Rules change, and local decisions override general patterns.

National forests (US Forest Service)

The Forest Service defines e-bikes as a type of motor vehicle. That means they are not allowed on non-motorized trails unless a trail has been specifically designated for them. They are generally allowed on roads and trails open to motor vehicles.

How to check: each national forest publishes a Motor Vehicle Use Map (MVUM), and some forests have designated specific trails for e-bikes. Ask the local ranger district if in doubt.

Interior lands (BLM, National Park Service, Fish and Wildlife)

Since a 2019 Department of the Interior order and the rules that followed, these agencies treat e-bikes differently from motor vehicles. Land managers can allow e-bikes on roads and trails open to regular bicycles, but they do it through site-specific decisions. In practice, some areas allow Class 1 e-bikes on mountain bike trails and many have not decided yet.

A recent example: in 2025 the BLM authorized Class 1 e-bikes on about 211 miles of mountain bike trails around Moab, Utah, effective March 2026, while keeping some trails closed where they connect to Forest Service land.

Wilderness areas are closed to all bicycles, electric or not.

State parks and local trail systems

This is where most riding happens, and it varies the most:

Some states allow Class 1 e-bikes wherever regular bikes go, unless a park says otherwise.
Some leave it to each park or county.
Many city and county trail systems have their own rules posted at the trailhead.
Bike parks set their own policies, and some limit or ban e-bikes on lifts or certain trails.

Why it is almost always Class 1

Most US states use a three-class system:

Class 1: assists only while you pedal, up to 20 mph.
Class 2: has a throttle, up to 20 mph.
Class 3: assists only while you pedal, up to 28 mph.

Class 1 is closest to a regular mountain bike in how it uses a trail, so it is what land managers usually allow. Bikes with throttles are generally not allowed on non-motorized trails. More detail in e-bike classes explained.

How to check a trail before you ride

Find out who manages it. National forest, BLM, national park, state park, county or private.
Check the official source. The managing agency's website, the MVUM for national forests, or the posted trailhead sign.
Check trail apps carefully. Many trail apps show e-bike access, but they are only as current as their last update. The sign at the trailhead wins.
Ask the local trail organization. They usually know the current rules and any pending changes.
When in doubt, do not ride it.

Why it matters so much

Trail access is shared and fragile. Every e-MTB ridden on a trail where e-bikes are banned gives anyone who wants to restrict mountain biking an easy argument. Following the rules is not just about avoiding a ticket; it is how e-MTB access grows instead of shrinking.

And if someone at the trailhead questions whether you belong there, being able to say "Class 1, and this trail allows it" ends the conversation fast. For the rest of the conversation, there is what to say back, or the Watts tee.
