Love it. My wife and I both have 2006 Bad Boy Ultras. They are great for all sorts of riding. We rode them 700 miles through Thailand without a single problem; we ride them all over the trails in and around our home in DC, and they are capable off-road bikes, too. We upgraded the brakes to XT hydros, though. The BB5s it comes with suck. We also put on carbon handlebars and seatposts, and more comfy seats: a Terry Ti Butterfly for the wife, and a WTB Ti Laser for me. (Note that the "Cannondale" and "Hand Made in USA" decals are reflective. No flash for the top picture; flash on for the bottom picture.)

Here's mine on its 700cx28 wheels/tires in Thailand:


And here's mine on 26x2.3s at home:
