Hello I am very interested in buying this for my 15 year old son. He is a large lad, about 300 pounds and I think this is a great way to help him lose weight. Do the handle bars come in longer lengths? He is 55 inches wide across his shoulders and I think the handle bars grips are too close together for him to be comfortable. Do the handle bars come in longer lengths? Also what is the correct posture stance with the arms for riding? Are the arms to be straight down with locked elbows? Are the handle bars suppose to be taller up the chest height to allow for bent elbows? Many thanks, Mom
