The drawback of training wheels is that they act as a crutch for the child, preventing them from learning to balance. Young riders may find training wheels to be a little unsteady.

Balance Bikes: These bikes require the child to sit on the saddle, scoot, and balance because they have only two wheels and no pedals.
