What is the difference between Class 2 and Class 3 ebikes?

Please see the example below for California Classification:

• Class 1: Bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to assist when the e-bike reaches 20 mph.
• Class 2: Bicycle equipped with a throttle-actuated motor, that ceases to assist when the e-bike reaches 20 mph.
• Class 3: Bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to assist when the e-bike reaches 28 mph.

Please note that when you change the speed limiter, your ebike is no longer a class 2 ebike.

Legal note: Changing the speed limiter is at the rider's own risk. Please check your local ebike laws to make sure you’re not breaking any laws. Ariel Rider/Arba International is designing their ebikes to go at an optimal 20mph and is not liable for any damage that might occur due to high speeds. Components of the X-Class are subject to higher wear when compared to bikes without power assistance. This is because D-Class can travel at higher average speeds than regular cycles and has a greater weight. Higher wear is not a defect in the product and is not subject to warranty. Typical components affected are the tires, brake pads and rotors, suspension forks, spokes, wheels, and the battery pack.
