First step...my wife and I purchased a new pair of Sun USX HD trikes. I'm in my early 60s and she is in her mid 50s and we aren't concerned anymore about speed. We were looking for comfort and I was looking for something that would be easy on my double replacement knees and these trike filled the bill. Yes they are a bit heavy...65 lbs, but as I said, we wanted comfort not speed. We both love our trikes, and who knows at one point in time we may move up to a lighter Delta. By the way, I won't even attempt to sit on a Tadpole. I've seen them at bike shops and wonder just how people sit down on these things and then get up off them. Too low for me.

Get a chance though, check out the Sun USX HD. Oh, one other item of mention, my wife and I did test ride the Sun X3 AX and the "only" thing we did not like about the trike was the "ape" bars. We both felt that after a while our arms would get tired and the trikes do tip quite easily up at speed.
