As Class 4 e-bikes have lots of power, they are the perfect bike for carrying big loads over very harsh terrain, Overlanding, hunting trips, or any extreme wilderness riding.

With the extra power and torque, you can haul large cargo loads up steep gradients or over loose terrain without a problem. This is especially helpful for riders who need to pack out meat from a hunting trip for example. In addition, you can reach higher speeds, allowing you to cover greater distances than lower-class e-bikes

Because these bikes are mostly used for off-road terrain, they usually come with excellent suspension, puncture-resistant fat tires, powerful hydraulic disc brakes, and other useful off-road components.

What Are E-Bike Classes?

Electric bicycles are generally categorized into three different class groups. In the USA, these groups are as follows:

  • Class 1: Max power 750W, top speed 20mph, pedal-assist sensor (PAS)
  • Class 2: Max power 750W, top speed 20mph, PAS and throttle
  • Class 3: Max power 750W, top speed 20mph with a throttle, 28mph with PAS

However, there are several bikes that do not fit into these classes and are often considered class 4 e-bikes. Class 4 has the same restrictions and requirements as dirt bikes, mopeds, and scooters.

Class 4 e-bikes can have motors over 750W. In this article, the motors range from 1,000W to 3,000W. Additionally, max speeds are not limited and these bikes can use PAS or throttle.

As mentioned above, class 4 eBike speed and power (Watts) are the main distinctions to the other e-bike classes. These electric bikes are considered the same as mopeds and scooters and are subject to the same restrictions and legislation.

Because of this extra power and speed, this type of e-bike is most commonly used for off-road riding. Also, as a high-powered motor vehicle, riders must have a license and registration to ride class 4 e-bikes on the road.

Key features of class 4 eBikes:

  • Throttle and/or pedal assistance
  • Top speed may be more than 28mph
  • The motor can be more than 750W
  • Mostly need registration and licensing for riding on the road

Class 4 vs Class 2 E-Bikes

Both Class 4 and Class 2 are electric bikes with throttle and PAS.

The main difference between these two classes is there are no legal limits on Class 4 e-bikes in terms of power and max speed. Whereas, Class 2 e-bikes are limited to 20mph using either throttle or PAS, as well as a maximum of 750W power in the motor.

Apart from that, these bikes are very similar but class 4 e-bikes are likely to be optimized for more extreme riding conditions while class 2 models work great as city/commuter bikes too.

Are 1000W eBikes legal?

Most states have laws that are limiting eBike motors at 750W. That makes 1,000W electric bikes more likely to be classified as a scooter or moped.

Electric Bike Rules & Regulations Explained

Electric bikes themselves might be easy to use, but the laws around their usage, particularly in the United States ...

However, there are some states where eBikes can have a motor of 1,000W. In addition to motor wattage, there are usually many other factors you must check.
