If you've shopped for an electric bike in the U.S., you've seen the label "Class 2." It's one of the most common e-bike types on the road, and it's the class most people mean when they ask for an e-bike "with a throttle." This guide explains what Class 2 means, how it differs from the other two classes, and what to check before you ride one where you live.
Class 2 E-Bike Meaning in One Sentence
A Class 2 e-bike has a motor that can move the bike with a throttle or help while you pedal, and the motor stops assisting once the bike reaches 20 mph. In most states that use the three-class system, the motor is also limited to 750 watts.
The Three Parts of the Definition
1. A throttle is allowed
This is what sets Class 2 apart. A thumb or twist throttle lets the motor move the bike without pedaling, which helps when starting from a stop, crossing an intersection or riding with a heavy load. Most Class 2 bikes also offer pedal assist, so you can choose between the two. Our guide to pedal assist vs throttle mode covers when each one makes sense.
2. Motor help ends at 20 mph
Whether you use the throttle or pedal assist, the motor cuts out at 20 mph. You can still go faster by pedaling hard or riding downhill, but the motor won't help above that speed. That limit is the reason Class 2 bikes are usually treated like bicycles rather than mopeds.
3. Motor power is capped
Most state laws that follow the three-class model limit the motor to 750 watts. Spec sheets often list a rated (nominal) figure and a higher peak figure, so check how your state's law describes the limit and read both numbers on the product page. For a closer look, see how a 750-watt e-bike is classified.
Class 1 vs Class 2 vs Class 3 at a Glance
| Class 1 | Class 2 | Class 3 | |
|---|---|---|---|
| Throttle | No | Yes | Usually no (varies by state) |
| Motor assists up to | 20 mph | 20 mph | 28 mph |
| How the motor helps | Only while pedaling | Pedaling or throttle | Only while pedaling |
| Typical extra rules | Fewest restrictions | Some trails limit throttles | Age limits, helmet rules and path limits are more common |
The full breakdown, including how each class is labeled, is in our guide to e-bike classes explained. If you're deciding between the two faster-feeling options, read Class 2 vs Class 3 e-bikes.
Where Can You Ride a Class 2 E-Bike?
In many states, a Class 2 e-bike can ride where regular bicycles ride: streets, bike lanes and many shared paths. There are common exceptions worth knowing:
- Trails and natural-surface paths. Some parks and trail systems allow Class 1 but not Class 2, because of the throttle. Rules are set locally, so check the trail's posted signs or website.
- Sidewalks. Many cities don't allow e-bikes on sidewalks at all, whatever the class.
- Federal and state lands. Policies differ by agency and by individual park.
A few states don't use the three-class system, or add their own rules on top of it. Before your first ride, look up your state. Our e-bike speed limits by state article is a good starting point, and California riders can check whether 750-watt e-bikes are legal in California.
Is Class 2 a Good Choice for Teens?
Many families choose Class 2 for younger riders because the 20 mph limit is the lower of the two common speed limits, and in several states Class 3 comes with a minimum rider age. Age and helmet rules still vary by state, so check e-bike age requirements by state before you buy. It also helps to talk with your teen about speed before buying.
What Can Change a Bike's Class
An e-bike's class depends on how it's built and set up, not only on the sticker. Raising the speed limit, swapping in a different controller or motor, or adding a throttle to a bike that didn't come with one can move it out of Class 2. In some states, that can mean the bike is no longer treated as an e-bike. Our article on e-bike speed limiters explains why the limit is there. If a listing you're looking at doesn't state its class clearly, these questions to ask the seller can help.
What to Check on a Class 2 Spec Sheet
- Class label and top assisted speed. It should say Class 2 and 20 mph.
- Motor rating. Look for both the rated and peak figures.
- Throttle type. Thumb or twist, and whether it can be repositioned.
- Safety certification. UL 2849 covers the e-bike's electrical system, including the battery, charger and motor working together.
- Range and battery. Throttle riding uses more energy than pedal assist, so plan around the low end of the listed range.

FAQ
What is the difference between Class 1 and Class 2 e-bikes?
Both stop assisting at 20 mph. A Class 1 e-bike only helps while you pedal, while a Class 2 e-bike also has a throttle that can move the bike without pedaling.
Can a Class 2 e-bike go faster than 20 mph?
The motor stops helping at 20 mph. You can go faster under your own power, such as pedaling hard or riding downhill, but the motor won't add speed above that point.
Do you need a license to ride a Class 2 e-bike?
In most states that use the three-class system, Class 2 e-bikes don't need a driver's license, registration or insurance. A few states have different rules, so check your state's current law.
Is a Class 2 e-bike street legal?
In most U.S. states, yes, when it stays within the Class 2 limits. Local rules on paths, sidewalks, trails and rider age still apply.
Are all Macfox e-bikes Class 2?
Yes. Every model in the current Macfox lineup is sold as a Class 2 e-bike with a 20 mph top assisted speed.
