Kids Bike Saddle Height Calculator Correct saddle height for a kids bike depends on the age of the child and type of bike. When just learning to ride, it’s important for a child to be able to sit on the saddle with both feet on the ground, so they can push themselves along and learn to balance. As their skills improve, and they begin pedaling on their own, you can raise their saddle for more efficient pedaling. Common saddle heights for kids bikes are described below.
