Think about your current sulky's. Are they worn out? Why? Chances are it's because of the almost constant contact with the ground. The daily wearing and tearing, banging and bending slowly destroys them. The unique design of theBronco Rider places the "main frame" of the sulky over 4 inches above the ground, away from all of this wear and tear. Only the actual foot platform rides near the ground. So if it does become worn or damaged you can quickly and inexpensively replace only the foot platform.
