Who decides, and what they usually say
| Where you want to ride | Who sets the rule | What it typically says |
|---|
| City and county paved bike paths | The city or county parks department | Class 1 and 2 usually permitted; Class 3 often excluded or speed-limited |
| State park and state rail trails | The state parks or DNR agency | Varies by state; many publish a class-based rule and a posted speed limit |
| National Park Service units | The park superintendent | Allowed where traditional bicycles are allowed unless the superintendent decides otherwise; never where bikes are prohibited; throttle-only riding restricted |
| Bureau of Land Management land | The local BLM office | OHV areas and motorized trails are open; non-motorized trails need a specific local decision first |
| Designated wilderness | Federal statute | No bicycles and no e-bikes, anywhere, with no local discretion |
| Private and conservancy rail trails | The trail organization | Set by the trail's own policy; check its website before you drive there |
National parks: allowed where bikes are allowed, with two catches
The National Park Service rule, published in the Federal Register in November 2020, defines an e-bike as a two- or three-wheeled cycle with fully operable pedals and a motor of not more than 750 watts, and establishes the three-class system. Superintendents may allow e-bikes wherever traditional bicycles are allowed.
Two things to know. First, e-bikes may not be used anywhere traditional bicycles are prohibited — so a trail closed to bikes is closed to you, and both are prohibited in wilderness areas by statute. Second, a superintendent may restrict e-bike use, impose conditions, or open a road or trail to some classes and not others. Which means the answer genuinely varies park by park and even trail by trail inside one park.
There is also a rule specifically aimed at throttles: Class 2 riders may not use the throttle exclusively for an extended period without pedaling, except where public motor vehicles are allowed. Throttle bikes are not banned; cruising for miles without turning the pedals is. That is worth knowing if you bought a Class 2 bike precisely so you would not have to pedal.
BLM land: the rule that opened nothing
The Bureau of Land Management amended its off-road-vehicle regulations in December 2020 to define e-bikes — a bicycle with a motor of not more than 750 watts, two or three wheels, fully operable pedals, Class 1, 2 or 3. The amendment lets authorized officers permit e-bikes on non-motorized roads and trails through later planning decisions.
The part people miss is the BLM’s own caveat: the rule does not, by itself, open any non-motorized trail to e-bike use. A local decision has to come first. In practice that means BLM OHV areas and motorized trails are open to you now, and a given non-motorized singletrack may or may not be, depending on whether that office has made a decision. Call the local office; they are used to the question.
Rail trails: the best riding, and the rule to read
Rail trails are where most of this riding actually happens, and they are the most e-bike-friendly surface in the country: flat, long, often crushed limestone, and managed by organizations that have thought about this question.
Expect a published policy in one of three shapes — all classes permitted, Class 1 and 2 only, or a posted speed limit that applies to everyone. The speed limit is the one to take seriously, because a 15 mph limit on a busy crushed stone path is enforceable and sensible, and a 20 mph Class 2 bike on a throttle will exceed it without the rider noticing. That is the entire argument for a computer: not performance data, just knowing what your speed actually is on a path full of dogs, kids and walkers. Our bike computer picks cover the cheap ones that do this well.
Singletrack and mountain-bike trails
Different question, different answer. Purpose-built mountain-bike trails are often managed by a local club under an agreement with a land manager, and many of them permit Class 1 only — no throttle. That rules out most value e-bikes, which are Class 2 or unclassified, before any argument about whether a 70 lb hardtail belongs on that trail in the first place.
Our honest read is in e-bike vs mountain bike: if real off-road riding is the goal, the better route is often a conversion kit on a proper mountain bike, and our conversion guide covers that. For the trail riding most people mean, our best e-bikes for trails roundup ranks the value bikes on published class first, which is exactly the order this page argues for.
Ride like you want to keep the access
E-bike trail access is still being negotiated in most states, and riders are part of the argument whether they intend to be. The BLM publishes trail etiquette that applies identically to bikes and e-bikes, and it is worth taking seriously for self-interested reasons: follow posted speed limits and directional rules, stay off the trail when it is wet and soft, pass considerately rather than widening the trail, announce yourself with a voice or a bell, and keep group sizes reasonable.
Two practical notes. A quiet bike approaching at 20 mph is genuinely startling — call out early, because the walker cannot hear a hub motor. And slow right down around horses and dogs. The person who decides whether e-bikes stay welcome on your local trail is often the person you just passed.
Carry the basics too, because a flat on a rail trail is a long walk pushing a bike that weighs as much as you do: a multi-tool, a pump, and a tube that fits. Our safety guide has the rest, and the flat-tire guide covers the part that is harder with a hub motor.
