I am 6'9" not smug and "Very thankful" for all of you for your input. I'm 58 yrs. old (arthritic)and moved away from a gym with a pool. Bicycling seemed a natural since I really need non-impact cardio. I really appreciate all the help. This is the first time in about 45 years I have done anything on a bike
Thanks to all
