Using the Kink Coast 12 Balance Bike is easy. First, adjust the seat height to a comfortable position for your child, which can range from 14.25' to 16.75'. Then, let your child straddle the bike and place their feet on the ground. They can start by pushing themselves forward with their feet to build balance and coordination. When using the bike, make sure your child wears proper safety gear like a helmet. Avoid riding on rough or wet surfaces to prevent accidents. For maintenance, regularly check the tires for proper inflation and the parts for any signs of wear and tear. If you notice any loose parts, tighten them immediately. Keep the bike clean by wiping it down after each use.
