The Sun EZ-3 USX HD model is designed to be a comfortable ride, even for those who may have some extra weight. The under-seat steering allows the rider's arms to relax while pedaling in comfort. It has a wide range of gears to allow for slow speeds going up a hill to fast speeds for on the flat and downhill. The suspension in the middle of the Trike adds to the comfort.
