The Evolution Curb Climber is an add-on pedal that mounts to the rear frame of a rollator near the wheel. Stepping down on it tilts the walker backward and lifts the front wheels clear of a curb, step, threshold, or uneven ground. Because the pedal sits behind the wheel axle, the wheel becomes the pivot and only light downward pressure is needed. That turns an arm lift into a foot press, so the hands stay on the handles for balance. It can be operated by the user or by a caregiver walking behind. Features Foot-operated step-down pedal Mounts to the rear frame near the wheel Designed to make it easier to clear curbs, steps, and thresholds Uses body weight instead of arm and grip strength Model-specific accessory Directions for Use Bring the front wheels up close to the curb edge. Keeping both hands on the handles, press down on the pedal until the front wheels lift clear. Push forward so the front wheels land on the curb, then release the pedal and roll the rear wheels up. Check that the mounting hardware is secure before each use. Do not use the curb climber while seated on the walker. Do not apply the brakes while tilting the walker. Do not use the walker on stairs or escalators. Do not install this part on a walker model other than those listed below.
