Query: study stainless steel frame, good materials of construction

bought this one over other because it has the rubber wheels, the other were plastic and doesn't go very well over gravel driveway. This has steel frame and nice paint job. The seat and handle bars are all adjustable for different proportions. All in all, good product that I suspect will last even with my tornado of a son.
