Using your Envy Prodigy S9 scooter is easy. Just step on the deck, hold the handlebars firmly, and start pushing off the ground to move. When you want to stop, use the brake system. Remember to wear proper safety gear like a helmet and knee pads every time you ride. For maintenance, regularly check the wheels for any signs of wear and tear. Make sure the grip tape on the deck is in good condition. If it starts to peel off, replace it. Also, keep the bearings clean and lubricated to ensure smooth rolling. Check the tightness of the bolts on the handlebars and the clamp periodically to prevent any parts from coming loose.
