The Catrike Expedition has been a favorite of Trike riders for years.  It is designed for the long haul, and it adeptly traverses hard surface roads and crushed lime trails with ease.  It sports a 26" rear wheel for a longer and more comfortable wheelbase as well as a higher gearing translated into higher speeds.  The standard Catrike neckrest is included as are the comfortable wristrests.
