A fully enclosed chain guard is the first thing to notice on this 14-in toddler bike: the cover runs the whole chain so cuffs and laces stay clear of the sprocket. The saddle is soft padded rather than hard plastic, which matters on a bumpy sidewalk. The hand brake lever sits nearer the grip than an adult lever so small fingers can pull it properly, and back-pedaling brakes the rear wheel. It fits riders 37.5 in to 43.5 in tall, ages 3 to 5, on a 99-lb rated seat, and arrives 85 percent pre-assembled.
