Electric bikes are classified into different categories based on their power and speed capabilities. The classifications help riders, manufacturers, and regulatory bodies standardize the usage and ensure safety. Let’s dive into the details of Class 1, 2, 3, and 4 electric bikes and compare their features in a tabular format.
Class 1 E-Bikes
Class 1 e-bikes are pedal-assist only, meaning the motor provides assistance only when you are pedaling. The motor cuts off when the bike reaches 20 mph.
Class 2 E-Bikes
Class 2 e-bikes have both pedal-assist and throttle modes. The throttle mode allows the bike to be powered without pedaling, but the motor assistance still cuts off at 20 mph.
Class 3 E-Bikes
Class 3 e-bikes are similar to Class 1 but with a higher speed limit. They provide pedal assistance up to 28 mph. These bikes often come with a speedometer.
Class 4 E-Bikes
Class 4 e-bikes are high-powered bikes that can exceed 28 mph. They often have motors more powerful than 750W and are not legally considered bicycles in many places, requiring registration and adherence to motor vehicle laws.

- Class 3: Suited for faster commutes and sportier rides, often preferred by fitness enthusiasts.
- Class 4: Best for off-road adventures and use on private property due to their higher speed and power.
Safety Equipment
- Standard bike safety gear is sufficient for Class 1 and 2.
- Class 3 riders should consider additional safety measures due to higher speeds.
- Class 4 riders should use full protective gear given the bike’s higher speeds and power.
