Using this Pedal Bing 14-inch kids' bike is easy. First, make sure your child is within the recommended height range of 76cm - 92cm. If your child is still learning to balance, keep the training wheels on. You can adjust the training wheels without any tools as your child gets better at riding. When your child is ready to start pedaling, they just need to sit on the soft foam saddle, put their feet on the short cranks, and start pedaling forward. To stop, they can use either the coaster brake by pedaling backward or the front brake. As for maintenance, keep the bike clean by wiping it down after use. Check the brakes regularly to make sure they're working well. If you notice any loose parts, tighten them up. Also, store the bike in a dry place to prevent rust.
