Thanks everyone for the info, i appreciate your time. I have looked at the trikes by greenspeed and cattrike etc.. i have two very bad knees and i would need a crane to park my but in the cockpit of one of those low ridin trikes. the sun ez 3 are 18 inches off the ground and to me that would be easier to get on and ride. we arent into speed versus distanc we just want the exercise have some fun and meet some new people. thanks for the info.. later ..
