Using this scooter is easy! First, adjust the T - bar to a comfortable height for the rider. Then, unfold the scooter using the side push button. You can also switch it to trolley mode when needed. To ride, stand on the deck, hold the grips firmly, and start pushing with your foot. When you need to stop, use the rear brake. Here are some things to note: The max weight allowance is 50kg, so make sure the rider doesn't exceed this. It's for kids aged 3 and above. For maintenance, keep the scooter clean. Wipe it down regularly to remove dirt and debris. Check the wheels and bearings periodically for any signs of wear. If the grip tape gets worn out, you can replace it to maintain the antislip function. Also, make sure the steering lock button and folding system are working properly before each use.
