Nowadays the variety of electric skateboard wheels raised as well as the development of their technical features. Some years ago you just were able to choose between different colors and sizes, which limited the level of comfort. You also always had to think of the suitable pulley so it fits together with the respective adapter on your eBoard. Now the new generation of electric skateboard is equipped with both types of Adapters (ABEC11 / Flywheel & KEGEL) so you just have to choose Size, Color & Technical Features. We generally suggest eSkate Wheels with focus on great suspension because that's the most valuable thing for you & your eSkateboards health.
