Query: surprisingly sturdy

My kid is a physical one. He got this as a present at his first birthday. It was by far his favorite gift and has played with it nearly daily for almost a year (has been great inside the house and out). He recently has taken to standing on it, which of course we try to stop. Still, he has never toppled over on it even with all of his 28 pounds on the bar between the front wheels. He has also balanced himself precariously on the center bar while holding the handle bars or a piece of furniture and has stood on the seat like Curious George. The one and only time he toppled it over was as he drove it off the steep side of our patio that is about 6 or 8 inches tall. Luckily it was into the grass and he was only scared, not hurt. I'm amazed by how well balanced this bike is.
