A few years ago a neighbor gave one to me. He knows I like to work on bikes and a friend of his wanted to get rid of it. Somebody had taken apart one of the twist shifters in an attempt to change the cable or something and failed.

It's a decent bike but no one in the family really wanted it so after a year I sold it. It's a bike for getting around, - not going fast. To me that's really the downside to an upright position. It also may not be the most comfortable bike to ride a 100 miles on but I'm sure plenty of people have on similar bikes.

If you're happy with it after 2 day test period then I'd go for it. Ride it for a year or two and then you'll have a better idea of what you want in your next bike. Or you may decide the Cross fit is just fine.
