4. Istruzioni per l'uso
Prima di ogni corsa, eseguire un rapido controllo di sicurezza:
- Freni: Squeeze both brake levers to ensure they engage smoothly and stop the wheels effectively.
- Pneumatici: Check tire pressure. The 14-inch pneumatic tires are suitable for asphalt and dirt roads, offering stability and comfort.
- Sterzo: Ensure the handlebar turns freely without excessive play and that the steering limiter functions as intended.
- Seat & Handlebar: Confirm that the seat and handlebar are at the correct height for the rider and are securely tightened.
- Pedals & Chain: Ensure pedals are securely attached and the chain is clean and lubricated (if applicable for pedal mode).
Encourage your child to practice riding in a safe, open area away from traffic. Start with the balance bike mode if they are new to cycling, then introduce training wheels, and finally transition to a standard pedal bike as their skills develop.
