Don't use training wheels!! Your kids won't learn how to balance or lean into turns. This is a quality balance bike that retails for $130 new on Amazon. It is lightweight (critical) with never flat tires and an adjustable clamp seat post. A regular kids bike is too heavy to learn on even with the pedals off. All my kids were riding bikes confidently by 3 years old because they started with the right type of balance bike. Search "Two Wheeling Tots Balance Bike" to learn about the need for balance bikes. In great condition!
