How can I teach a child to ride a bike without training wheels?

To teach a child to ride a bike without training wheels, start by adjusting the seat so their feet can touch the ground. Have them practice balancing by scooting along with their feet up. Then, hold the back of the seat and run alongside them as they pedal. Encourage them to look straight ahead and practice turning. Gradually let go as they gain confidence and balance. Celebrate their progress and provide gentle guidance as needed.
