[4-light Wheels Compatible with RipStik] These wheels have a diameter of 68mm and a thickness of 24mm that meet the standard specifications of compatibility. [Lights Up Without Batteries!] These glowing wheels are made using special technology to generate electricity from the spinning movement and light up. Because of this, they can glow without batteries once installed. [Amazing Wear-resistance with a Hardness of 90A] These wheels have a hardness of 90A which is the most popular for riding in places such as cities, neighborhoods, streets, and parks. [ABEC-7 Bearings] Illuminating wheels have a disadvantage in that they're harder to turn because they convert movement into electricity. That's why ABEC-7 bearings are used to support smooth rotations. [The Smaller the Wheel, the More Stable It Is] Some people choose larger wheels because they're afraid of them wearing out, but the larger the wheels are, the more unstable their footing is. We strongly recommend choosing 68mm to reduce the risk of falls for kids and beginners. Size: 68mm (2.68") Hardness: 90A ABEC: 7 Pcs: 2 pack Color: Aurora 4 LED
