Kids Disney Princess Training Bike

My dad received it from a neighbor thinking it would be great for the nieces but they're too big for it. In fair usable condition but could do with a little TLC or repaint. My dad suggests that a new seat is probably a good idea. Length from wheel to wheel is 37 inches. Height to the top of the seat is approx. 19.5 inches (it is adjustable) Height to the handlebars is approx 28 inches. Seat length is 8 inches and its width at the widest part is approx. 6 inches.
