How fast can the D-class go?

Ariel Rider D-class ships with a 20mph speed limiter. This limit can be changed from the screen up to 35mph. 

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.
