Luminous wheels are powered by a magnetic bearing spacer in the core of the wheel. When you roll the wheel lights up, no charging necessary. Colors labeled "Glow" also glow in the dark.
Luminous wheels include 8mm magnetic spacers, if your skates use a 6mm axle, an adapter may be necessary. Please contact us if you are unsure what diameter axle your skates use. 6mm adapters are available
