Using your Grit Extremist scooter is easy. Just stand on the 6061 heat - treated alloy deck, hold the high - tensile steel riser handlebars, and start riding. You can adjust the height from the ground to the top of the bars to either 750mm or 800mm for a more comfortable ride. Whether you're riding on the street or in the park, the scooter's wheels and fork can handle it. For a smooth ride, make sure the Grit Soft Grips are firmly in your hands and use the Grit Flex Fender Brake to stop safely. When it comes to maintenance, regularly check the alloy double clamp and the head parts. Keep the wheels clean and lubricate the bearings every few weeks. Also, check the brake regularly to ensure it's working properly. And remember, this scooter is suitable for riders of all ages, but younger riders should always wear protective gear.
