I have a Soho S that I ride to work nearly every day. It's a blast to ride, but I live a couple of miles from downtown, so everywhere close by is pretty urban. I would not take it on anything worse than a well packed, very smooth trail. The tires that come with it are very easy to puncture. I also wouldn't mix racing like tires and gravel, just sounds like it could make for a bad day, imo.
