The versatile EasyPivot Model EP-81 is designed specifically to fit most children and smaller adults and to "grow with them." We've optimized the design of the Model EP-81 for low cost and high durability - including molded foam upholstery, a three-setting wheelbase, and a unique dual-position stop lock. The Model EP-81 uses the same frame as the Model EP-82 but has a shorter arm between the chest pad and pivot bolt. This is to accommodate a smaller person's shorter torso. To accommodate children with shorter legs, a multi-position foot base is available as an option. The EP-81 can be retrofitted with Model EP-82 parts as the user grows. The Model EP-81 will pass through a 26" wide opening.
