Seismic Megawatt 90mm – 74A

More miles per hour, distance per push, and blocks per watt! • The world’s fastest urethane and most progressive hub-and wheel engineering bring unparalleled rebound and superior energy efficiency to a huge 90mm-diameter shape. • Higher top speeds, longer push distances, and extended ESK8 battery life and riding range! • Next-level weight-saving Turbine™ hub features bigger vent holes for more accessible e-board pulley adapter fitting. • Hub structure ingeniously sculpted for highly-optimized routing of wheel rebound energy. • Width, edge profiles, and bearing seat offset finely calibrated for race-style grip and more consistent wear. • Half-millimeter concave running surface preloads edges, sharpens grip, enhances rebound
