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.
In simple terms, riders on a Class 1 bike must pedal (pedal-assist) in order for the motor to function. Class 2 riders can choose to pedal or simply engage the throttle for peddle-free cruising. Finally, Class 3 cyclists can pedal or cruise when going up to speeds of 20 mph, but must pedal when increasing to speeds 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.
