Fun, challenging, scenic - I agree, SNP East is hard to beat. This was once my regular ride when I lived on Tucson's east side, where I'd head out to the park via Old Spanish Trail from Broadway. With a mountain bike, the option exists to combine the road ride with a portion of the Cactus Forest Trail (the only singletrack in the park open to bikes) that bisects the loop road.
The Greenway on the South Rim is miserable on foot, from what I hear. Not to mention baffling, corralling trail users onto officially-sanctioned asphalt (welcome to the Grand Canyon dear hikers - this is it - you made it!) considering better options both existent and conceivable. Suppose cyclists can have it then.
