I have been off here for a while, but I am back in the land of the living and doing some more research. toolbear, you mentioned Terratrike Rover, I see that they are a bit less expensive, are they a good trike? I see the bottom end is a two speed bike, do you think that would be enough for me to start out on. I am looking to do this for exercise, I really need to lose weight so pedaling is good, but we have a lot of ups and downs in SW Virginia. For starters I may be going around the track at the local school just to get my stamina going. I am right at 300 pounds now and I just can't have that, I have to do something about it, you can guess what jogging would do to my joints and leaning on handlebars does to my wrist and shoulders.
