Using this bike is easy. First, adjust the seat height to a comfortable level for your child. If your child is just starting out, keep the training wheels on. When they're ready to try without them, you can remove the training wheels without using any tools. To pedal, your child just needs to push the pedals forward. To stop, they can use the coaster brake by pedaling backward or the front brake by squeezing the brake lever. When it comes to maintenance, regularly check the brakes to make sure they're working well. Also, keep the chain clean and lubricated. If you notice any loose parts, tighten them up. And remember, this bike is for kids between 76cm and 92cm in height, so don't let taller or shorter kids use it to avoid safety issues.
