The all new X3-USX utilizes our new unique X-Frame design. The X-Frame offers an easy step thru with a low center of gravity attained by three 20-inch wheels that are cambered in the rear to increase cornering stability. Also the X3-USX offers three wheel brakes and under-theseat steering along with the new Seat Track System with tilt adjustment. With this system, no seat components touch the frame. As with the rest of the SUN Recumbent line up, the X3-USX includes the new rattle-free and infinite adjust seat strut system along with updated graphics and color along with the great new tri-tone saddle.
