Our Barbie 18-inch bike is dressed to impress. The sturdy steel frame comes complete with removable, adjustable training wheels, a rear coaster brake, and a full chain guard. But, to be a Barbie bike, you need pizazz, so we added custom Barbie decals throughout, a love heart saddle, a Barbie handlebar bag, and bold white tires, just to make sure the 18-inch bike by Dynacraft would be stylish enough for your fashionable Barbie fan.
