An essential wheel for skaters who rely on braking performance Bright, visible night lighting: flashing wheels with luminous features and an external night LED sliding flash to improve visibility after dark. Energy harvesting while you roll: copper coils inside the wheel and magnetic rings in place of spacers generate electricity as the wheel spins, powering the LEDs without extra batteries. Clear braking performance: designed to support brakingfocused skating with reliable control and stopping capability. Easy to use on standard inline skates: inline skate wheels that fit typical skate setups, with an external LED slide flash for added effect. Key features Function Internal copper coils and magnetic rings generate electricity during rotation LEDs flash to enhance night visibility and styling External sliding night LED adds an additional light source along the wheel Compatibility Intended for inline skates with standard wheel hubs and axles Designed to work with common inline skate configurations; check your skate model for fit Size Available in standard inline skate wheel sizes; exact options should be confirmed in the product listing for your model Material Wheel construction follows typical inline skate wheel design; internal components include copper coils and magnetic rings as described Performance Luminous features provide visibility in low light Built to support braking performance while skating Energy generation occurs automatically as the wheel rolls, powering the LEDs Use scenarios Night urban riding: commute or cruise through streets and parks with enhanced visibility and a distinctive look. Campus or neighborhood skate sessions: safer group rides after dusk thanks to bright LEDs and reflective light. Night events or performances: eyecatching lighting on wheels adds a stylish element to routines or shows. Care and maintenance Regularly inspect the wheel and LED components for secure attachment and wiring integrity. Ensure the LED slider is clean and unobstructed for consistent flashing. If wheels are used in wet or dirty conditions, dry and inspect after use to maintain performance.
