The deck of the Mg is solid magnesium (no kidding) providing the lightest deck structure of our wide-deck models. The Mg has a beautiful, sleek, and modern look. We believe the Xootr Mg is the most advanced push scooter ever made, which is why it is our best selling model. It offers a wide deck which provides comfortable cruising, allowing you to have both feet side by side on the deck unlike other adult kick scooters such as the Razor A5 Lux, Know-Ped, or Micro. The deck is cast in solid magnesium, powder coated, and then CNC machined. The wheels are die cast aluminum rims with our ultra-low-resistance polyurethane tire (black). Includes rear fender/brake kit.- Frame construction: Cast aluminum.
