To use the Wahoo 24 Trail, simply adjust the seat to a comfortable height for your kid. Make sure your child wears a proper helmet and safety gear before hitting the off - road trails. When riding, encourage them to use the brakes gently at first to get a feel for how they work. As for maintenance, regularly check the tire pressure. If the tires look low, use a bike pump to inflate them. Also, wipe down the bike after each use, especially if it's been in muddy conditions. Every few months, take it to a professional bike shop for a full check - up. Avoid riding the bike in extremely wet or salty conditions as this can cause rust and damage.
