Using your new stunt scooter wheel is easy. Just install it on your scooter following the normal wheel - fitting process. Make sure the ABEC 9 bearings with the spacer are properly in place. When riding, whether on the street or in the park, the wheel's great grip will give you a smooth and stable experience. As for maintenance, keep the wheel clean. After a ride, use a soft cloth to wipe off dirt and debris. Check the bearings regularly to ensure they're spinning freely. If you notice any strange noises or reduced performance, it might be time to clean or replace the bearings. Be careful not to over - tighten the wheel when installing it, as this can affect its rotation. Enjoy your ride!
