Well, after making the fatal mistake of letting my wife ride my Road, she decided she liked it better than her delta trike. So, now the big decision. Let her keep my limited edition red color Road and me get a 5.5.9 in atomic orange, or to let her get a Road of her own. I kind of like the features of the 5.5.9, especially the larger rear tire. I can see that being of a benefit on longer rides. But I'll honestly probably never use the folding feature - and that strikes me as a possible failure point. For carrying, we will be getting an Alpaca style rack (2 inch) to mount our trikes on - so folding is not that important since we also have a large garage to store them in. Was wondering if anyone has owned both and can give feedback to which - for a casual rider that may start doing some long distance riding - a better trike.
