I haven't tried to find any threads here, but until now I had never heard of a "push" bike. A young co-worker a few years ago mentioned taking the pedals of his toddlers bike and the theory why. Is push code for taking the pedals off or actually special training tool with no capacity for pedals? The latter seems like a waste of money. My recollection as a kid was neither. I vaguely remember my dad pushing me around for a day by the sissy bar of a too big bike until I got it and I've been hooked ever since. My daughters briefly had training wheels. I think training wheels worked for decades. Feels like a fad, or personal choice to me. Not sure it really matters.
