Using the SmarTrike T1 Adjustable Scooter is easy. First, adjust the scooter to one of the 3 stages according to your child's age and ability. For younger toddlers, let them sit on the foam seat and scoot around. As they get more confident, remove the seat and let them stand and ride. Hold the handlebar firmly with the soft - touch rubber grip. Use the extendable handlebar to adjust the height for a comfortable ride. The rear brake can be used to slow down or stop. When riding, make sure your child is in a safe area, away from traffic and other hazards. Always have your child wear a helmet. To maintain the scooter, clean it regularly with a damp cloth. Check the wheels, handlebar, and brake periodically to ensure they are in good condition. If the LED lights stop working, replace the batteries as needed.
