The Rifton Tricycle Front Pulley can be added to the Rifton Tricycles to help keep the pedals level for individuals that have extreme extensor tone that is stimulated by pushing down on the pedals. The Front Pulley works in conjunction with the Rear Pulley (which is a standard feature on all Rifton Tricycles) to keep the pedals parallel with the ground. The Rifton Front Pulley can be used with ALL Rifton Tricycles.
