Actually I just visited Sheldon Browns gear calculator and with a 40 tooth chain ring an 18 tooth sprocket and a SA wide ratio hub you would get 45,60 and 80 inches using 700x35 tires. I'm not sure if this is the correct ratio possible on the sprocket chain ring combo or if one needs a particular ratio for it to work right but.........I am elder and corpulent so I have faith that the above would serve me admirably whereas a younger fellow might find it a yawn and aspire to a greater challenge of his vigor.
