Using the Apollo Neo+ 24 7s is easy. First, adjust the seat and handlebars to fit your child's height. To start riding, just hop on and start pedaling. Use the twist-grip shifters to change gears according to the terrain - lower gears for uphill and higher gears for flat or downhill. When you need to stop, gently squeeze the front brake levers. Here are some important notes. Make sure your child always wears a helmet for safety. Don't let your child ride on rough or wet roads without adult supervision. For maintenance, regularly check the tire pressure and keep it at the recommended level. Wipe the bike clean after each ride to prevent dirt build - up. Once in a while, lubricate the chain to keep it running smoothly. Also, have a professional check the brakes and gears periodically to ensure they are in good working condition.
