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.  For all the specs please see the SunSeeker web page by clicking HERE and then on the EZ-3 USX HD icon.
