Durable PU wheels for longer use quality polyurethane (PU) construction resists wear and provides effective shock absorption. Result: fewer replacements, smoother rides over uneven pavement, and a firmer grip on typical skating surfaces. Thickened onepiece pulley bracket for safety and strength Reinforced, anticollision pulley bracket is designed to resist cracking and maintain structural integrity during movement. This adds durability and stability under normal skating stresses. Builtin LED flash for visibility and style Wheels include LED flash functionality to increase visibility during lowlight or night use while adding a modern look. The design remains wearresistant and suitable for higherspeed rotation. Stability and control for confident skating The wheel profile and semiprecision bearings deliver consistent traction, good control, and smooth rolling at recreational and commuter speeds. Bearings reduce friction for a faster, more fluid ride without sacrificing stability. Who benefits and why Commuters: Improved visibility and reliable grip make evening rides safer and more consistent on city paths. Recreational skaters: Durable wheels and a sturdy bracket reduce maintenance and the risk of component failure during leisure sessions. Fitness skaters: Smoothrolling bearings and shockabsorbing PU material support longer sessions with better control and comfort.
