Using your Envy Colt S5 Complete Scooter is easy. First, adjust the handlebars to a comfortable height for you. Then, place one foot on the deck and use the other to push off the ground. When you want to stop, press the brake gently. As for maintenance, keep the scooter clean. Wipe it down after each use to prevent dirt build - up. Check the bolts regularly to make sure they're tight. If you notice any loose parts, tighten them right away. Also, inspect the wheels and hand grips for wear and tear. Replace them if they start to look worn. When not in use, store your scooter in a dry place to avoid rust and damage. Remember, always wear proper safety gear like a helmet and knee pads when riding.
