Can the angle of the saddle be adjusted?

No, the saddle tilt is not adjustable. However, this saddle has been specifically developed for each age group, so that each frame size (4, 5 and 6) has its own perfectly proportioned saddle that is tuned to the ergonomics of the rider for optimal comfort. The standard saddle tilt has been carefully considered based on the bike's geometry to create a comfy and efficient riding position.
