The Skyfly bicycle, size 20, is generally recommended for children aged 5 to 8 years old, or those with a height between approximately 114cm and 132cm (3'9" to 4'4"). This size is a popular transition as kids outgrow smaller 16-inch bikes and are not yet ready for larger 24-inch models.
Key features of a Skyfly size 20 bike often include a sturdy frame for durability, comfortable seating, and reliable brakes for safety. 1 Many models come with training wheels that can be removed as the child gains confidence and balance. The design is typically kid-friendly with appealing colors.
