Using this Grit Extremist scooter is a breeze. Just step on the 6061 heat - treated alloy deck and hold the high - tensile bars. You can adjust the height from the ground to the top of the bars to 750mm or 800mm according to your preference. When riding, the soft grips and flex fender brake will give you a smooth and stable experience. For safety, always wear proper protective gear like helmets and knee pads. When it comes to maintenance, regularly check the wheels' bearings and the tightness of the clamp. If the brake starts to feel less effective, it might need some adjustment. Keep the scooter clean, especially after riding in dirty or wet conditions, to make it last longer.
