Another underappreciated feature of training/balance bikes are having a hand brake lever on the side where the front brake conventionally is on real bicycles.

My oldest (age four) is able to modulate his front brake usage immaculately, both when slowing down and stopping quickly. I didn't learn that skill until well into my 20's, and my wife still avoids the front brake to the point where I'm worried it might become a safety issue at some point.
