I know I can't be the first with this inquiry but here it goes. Mid 50's wanting to bike for a number of reasons. Just local stuff on the flat Florida terrain. Trying to get some exercise and maybe run a few errands. The problem is I have a herniated disk and sciatica. I tried out a recumbent briefly but it scared the hell out of me when traffic got within 10 feet of me. The people around here are not the most attentive drivers and unfortunately we have a pretty extensive population down here that continues to drive long after their vision and reflexes have deteriorated. Any suggestions for a comfortable ride at a reasonable price that I can try out? Or should I just take up swimming?
