Put together a road bike for my wife last week, she's verticaly challenged.
35cm frame, 650c wheels, 145mm crankset, 34cm handlebar.. altogether.. one tiny bicycle. She wants to do a century in October.
Over the weekend we went out for 18 mile ride, took 1 1/2 hour with food stop and multiple breaks.. I think I will do the same century with her on my recumbent.
