I own two Softrides and love them! I use my Powerwing 650 for triathlons, time trials, and just to kick my buddies ass occasionally. I also have an older model Solo for my road bike, although it's practically brand new because the original owner couldn't get into it and left it hanging for a few years. The Solo is like riding a caddie. I let people take it for a spin (yes, you have to spin)and they come back saying, "Wow, I could ride this all day." That being said, I'm fixing up an old lugged steel, 26" wheel touring bike to ride for ten weeks this summer. The seat is everything, then the legs and engine. I've had my ass whipped by kids on 25lb pieces of junk and it's a joy to see.
