  • Publication number: 20230129416
    Abstract: A step platform includes a mounting bar, an arm, an inner portion, and a platform. The arm is coupled to the mounting bar and extends vertically from the mounting bar. The arm is coupled to the mounting bar by a first joint. The inner portion is coupled to the arm and extends horizontally from the arm. The inner portion is coupled to the arm by a second joint. The platform extends horizontally above the inner portion. The platform is configured to support a user. The step platform is reconfigurable between a folded position and a mounted position by pivoting the mounting bar relative to the first joint and pivoting the arm relative to the second joint. The platform engages with a tractive element when the step platform is in the mounted position. The mounting bar is extendable or retractable to modify a length and a width of the mounting bar.
