E-Bike Classes Explained: 1-2-3, Go!
Delving into the world of e-bikes for the first time brings forth a dizzying lexicon of head-scratching jargon used to describe them: hub motor versus mid-drive motor; pedal assist and throttle assist; watts of power and Newton meters of torque.

Perhaps the most significant differentiator is the three-class e-bike system.
That’s Class 1, Class 2, and Class 3.
If you’ve ever shopped for an e-bike, you’re almost certain to have come across one or more designations. But what exactly do they mean? And where did they come from?
Let’s start with how the U.S. law has defined an e-bike, or more precisely, a “low-speed electric bicycle.”
E-Bike Classes: Legislation and Regulation
Passed by Congress in 2002, H.R. 727 establishes that a low-speed electric bicycle is “a two- or three-wheeled vehicle with fully operable pedals.” It has an electric motor with up to 750 W of power output (1 horsepower) and a maximum motor-propelled speed of 20 mph.
The law separates those bicycles from motorized vehicles, placing them under the purview of the U.S. Consumer Product Safety Commission, which regulates bicycles. The National Highway Transportation Safety Administration regulates automobiles, motorcycles (including electrics), and other high-speed vehicles.
However, so-called “e-bikes” within and outside H.R. 727’s parameters were — and continue to be — sold worldwide and end up rolling on roads and bike paths throughout the states. So the U.S. bicycle industry took it upon itself to help bring more order to the emerging e-bike market and help individual states. Each state holds authority over bicycle usage on public roads and bike paths and identifies where e-bikes might safely be ridden.
Industry groups like the Bicycle Product Suppliers Association (BPSA) and PeopleForBikes (PFB) worked together to create the three-class system. (Side note: The BPSA and PFB later merged under the PeopleForBikes name to more effectively coordinate on e-bike policy.)
The first beachhead in the campaign, literally and figuratively, was cycling-rich California. In 2015, the Golden State was the first to pass what PeopleForBikes now calls the “Model Electric Bicycle Law With Classes.”
A bicycle with a motor that provides assistance only when the rider is pedaling. It ceases to assist when the bike reaches the speed of 20 mph.
A bicycle with a motor that exclusively (typically via a twist throttle or thumb lever) propels the bike. It is incapable of assisting when the bicycle reaches the speed of 20 mph.
A bicycle with a motor that provides assistance only when the rider is pedaling. But it ceases to assist when the bike reaches the speed of 28 mph and is equipped with a speedometer.
Power output for all three classes is limited to 750 W/1 horsepower, as outlined in H.R. 727. Class 3 bikes exceed the federal law’s 20mph power-assisted speed limit. But the category is in alignment with the European designation for “speed pedelecs.” This includes e-bikes providing assistance only when the rider is pedaling, with the motor putting out at no more than 45 kph, equaling 28 mph.
‘Reasonable Access’ for E-Bikes
In its role driving e-bike policy, PeopleForBikes maintains that “U.S. laws should permit reasonable access to bicycle infrastructure for the three classes of low-speed electric bicycles, ensure that riders of electric bicycles can enjoy the same duties, protections, and rights as riders of traditional bicycles, and clarify that owners are not subject to vehicle laws that might apply to more powerful devices,” such as licensing.
As of this writing, 39 states have passed the three-class system in one form or another. However, significant variances exist from state to state.
Several states restrict or completely bar Class 3 e-bikes on bicycle paths. And New York — where some NYC food delivery workers riding high-speed throttle electric bicycles on roads, bike lanes, and even on sidewalks have stirred anger — created its own Class 3. This class encompasses throttle e-bikes cutting power at 25 mph (for use only in New York City) but does not recognize 28 mph pedal-assist-only e-bikes.
“The more popular e-bikes are — the more people are out riding on various types of bicycle infrastructure — the more these classes come into play,” said Larry Pizzi, an e-bike industry veteran who has been a critical player in the public policy efforts of both the BPSA and PFB. Pizzi currently serves as a chief commercial officer for Alta Cycling Group (home to bicycle and e-bike brands Diamondback, IZIP, and Redline) and sits on the PeopleForBikes’ board of directors.
As I said earlier in this story, loads of vehicles that manufacturers call “e-bikes” don’t fit the industry definition the federal law or PFB and its model legislation spell out. These vehicles have higher cutoff speeds for pedal and/or throttle assist. Or the motors exceed the 750W limit — sometimes by a lot. Maybe they don’t even have pedals.
often than not, these are products made or sold by brands with little or no track record in the bicycle industry. And they’re a problem for the companies looking to promote the safe use of the low-speed electric bicycles they sell.
“It’s detrimental to the rest of the category because they’re well beyond the power and speed criteria that define an electric bicycle,” Pizzi said, adding that building and selling these noncompliant vehicles exposes those brands to incredible financial risk.
Mislabeling of Class 3 E-Bikes Is Another Problem
Case in point: An e-bike with a 750W motor has a thumb throttle powering the bike up to 20 mph, and it also has pedal assist topping out at 28 mph. It’s stickered as a Class 3 e-bike. Is that correct?
Answer: No, it’s outside the class system. Class 3 e-bikes, as outlined by the model legislation, can’t have a throttle even if it tops out at the Class 2 limit of 20 mph. Still, many brands stack the classifications and call these Class 3s. A customer can remove the throttle for Class 3 compliance, but the stock e-bike is out of class.
Regulators have apparently overlooked this mislabeling practice.
“We want governmental organizations to step up and FOCUS on these issues,” Pizzi said. “Our hope is that they’ll reel them in.”

Electric Bike Classes
Many people aren’t aware that Utah state laws recognize three different classes of electric bikes. Before buying or riding an E-bike, you should understand the differences. Read on to learn about each class and which classes The Bike Shoppe carries. If you’re still unsure which e-bike to get, read our buyer’s guide for our whole selection of electric bikes.
Class 1 Electric Bikes
Here’s what defines a Class 1 E-bike:
- Pedal-assist only
- No throttle
- Max assisted speed of 20mph
- Max motor power limited to 750W
Class 1 E-bikes are pedal assist only. The only way to engage a pedal-assist motor is by good old-fashioned pedaling. There is no throttle of any kind.
Depending on the model of bike, riders can choose between three and five assistance levels. Each level assigns a range of output to the motor that can vary based on how hard or fast the rider pedals. For example, the Bosch system offers four assist levels: Eco, Touring, EMTB, and Turbo. Eco mode will provide up to 40% support while Turbo mode will kick in up to a whopping 250%.
The Bike Shoppe favors Class 1 E-bikes because they are safe and easy to use while offering an impressive amount of assistance. They provide an excellent workout for riders while nearly eliminating intimidating obstacles like hills. Utah treats Class 1 E-bikes like traditional mountain or street bikes, legally allowing them to be ridden where bicycles are permitted, including bike lanes, roads, multiuse trails and bike-only paths. However, take care in checking specific E-bike regulations for your area as rules can change between local, state, and federal agencies.
Class 2 Electric Bikes
Here’s what defines a Class 2 E-bike:
Class 2 throttle-assist E-bikes combine pedal-assist with throttle-assist. This class is often subject to additional restrictions and may not be the best option for non-motorized singletrack trails. Studies show that class 2 E-bikes can cause greater damage to trails than traditional bikes or even other E-bikes. The throttle actuation can cause these to be more difficult to ride and less safe than other types of E-bikes. At The Bike Shoppe, we’ve chosen not to stock any throttle-assisted E-bikes. It’s our opinion that pedaling is an irreplaceable part of the cycling experience. However, we understand that certain riders may benefit from a throttle-assist. To support these riders, we can order IZIP and Raleigh Class E-bikes.
Class 3 Electric Bikes
Here’s what defines a Class 3 E-bike:
- Pedal-assist only
- No throttle
- Max assist speed of 28mph
- Max motor power limited to 750W
We call class 3 the commuter class. Regular commuters absolutely love these E-bikes, and they’ve proven to be a realistic replacement for a car. They’re very efficient at getting a rider from point A to point B quickly, and they still provide an excellent workout. Because of their higher max speed, Class 3 electric bikes are prohibited on trails and paths like the Ogden River parkway. They are permitted on roads and on in-road bike lanes.
What Is A Class 2 Electric Bike? We Explain Ebike Class Differences
There are three class types of electric bikes. We break down their differences, discuss which class are Rad Power Bikes, and why it matters.
Why Are There Different Ebike Classes?
Similar to motorcycles, electric bikes are classified into different categories based on their basic functionality. Let’s review the three ebike class types, based on a model ebike law that most U.S. states have adopted as the basis of their state regulatory system:
- Class 1: Pedal-assist only; motor provides assistance all the way up to 20 mph.
- Class 2: Pedal-assist or throttle; motor provides assistance all the way up to 20 mph.
- Class 3: Pedal assist only; motor provides assistance all the way up to 28 mph.
Can ebikes go even faster? Technically, yes. However, Class 1 and 2 motors shut off at 20 mph, and Class 3 motors shut off at 28 mph. Any additional speed is gained by rider power alone, and/or decreasing elevation (riding downhill).
What Class Are Rad Power Bikes Ebikes?
Rad Power Bikes designs Class 2 ebikes. In fact, beginning in 2007, the company was one of the first to pioneer the combination of a throttle and pedal assist. When designing a safe, reliable, and enjoyable transportation solution, Rad took into account multiple factors: federal and local laws, bike usage, technology, and rider experience. The result: Class 2 ebikes with a full 750 watts of power.
Can Ebike Riding Be Illegal?
According to Chief Product Officer Redwood Stephens, the decision to design Class 2 isn’t a light one, and plays a factor into every bike Rad develops. First, Rad creates ebikes to be compliant under the CPSC (Consumer Product Safety Commission) regulations for safety requirements applicable to ebikes. Those regulations prescribe limits for motor power and the maximum speed that a bike can operate when powered solely by the motor.
Second, Rad Power Bikes are designed so our riders are comfortable that their ride is legal on most roads and bike paths, based on state laws. “We design our bikes to be safe, and compliant with the law,” confirms Stephens. In multiple states, ebikes with motors that provide assistance at or above 20 mph are not permitted on many types of bike-focused infrastructure. Riding beyond those state and local restrictions can go against traffic laws and regulations, and potentially require licensing and registration fees.
As a rider, it’s vital you check your local laws in the rare case a road or path is not yet following the model ebike laws that treat Class 2 ebike the same as a traditional bike. After all, what good is your bike if you can’t ride it?
About That Need for Speed
As Class 2 ebikes, Rad Power Bikes are engineered to not only perform well up to the 20 mph (the speed that the bike’s motor shuts off), but also accommodate additional speed that occurs when traveling downhill. However, some ebike brands are focusing on Class 3.
“To consistently travel safely at higher speeds, the bike frame, brakes, suspension systems, and more have to be engineered for that,” says Stephens. We asked Stephens if that was being done in the industry. “Not always. Higher speeds often requires engineering new parts from scratch,” explains Stephens, “but some brands are not upgrading critical systems that such speeds require.”
Safety and Technology
For Rad, our choice to FOCUS on building the best Class 2 ebikes comes down to providing ebikes that not only travel at safe speeds, but meet and beat rider expectations each and every day. Safety is paramount to ensuring bike trails and paths are accessible for everyone. Designing within Class 2 standards ensures that we are meeting that endeavor. It also ensures that when electric biking with your kids, passengers, or just for fitness and fun, a Class 2 ebike is designed to meet those needs.
At a Class 2 designation, Rad engineers strike that perfect balance between cost, quality, and safety. ensuring you get a safe ebike using quality parts; legal to ride in most places; and at a great price.
