This is a solid street wheel from Exway with a decent contact surface and a nice formula and a durometer of 78a. The wheels are also available in orange but with a slightly softer duro of 76a. Even if you don't have an electric skateboard, you can absolutely use these wheels as they follow the standard. Just make sure you don't get wheelbite. The wheels come in a pack of 4 wheels. If you want to combine it with pulleys and belts, you have a list of recommended pulleys and belts under the product description.
