Using the Pedal Zap 20 - inch kids bike is easy. Just hop on, hold the soft grips firmly, and start pedaling. The alloy levers are there for you to control the brakes when you need to slow down or stop. When you're riding on different terrains, the suspension fork and all - terrain tyres will help you have a smooth and stable ride. For kids who are still growing, you can use the quick - release seat clamp to adjust the seat height as needed. As for maintenance, keep the bike clean by wiping it down after each ride. Check the tyre pressure regularly to ensure good performance. Also, lubricate the chain every few weeks to keep the drivetrain working smoothly. If you notice any parts that seem loose or damaged, have them fixed right away to keep the bike safe to ride.
