In case anyone is still following this thread, I just bought a Cannondale Hooligan 8 and took it on a 15 mile test run yesterday. The verdict? Fast and fun is how I would describe it. Capable of explosive acceleration, responsive, but able to burn a trail in a straight line. Very rigid, feels (and is) much tighter than a folder. The supplied seat is a loser, but aren't they all? The ride is comfortable thanks to the chubby tires, but unlike what some people might believe, the tires don't feel heavy at all, possibly because their circumference is so small.
This is more of a cross between a city and a road bike than a city and a BMXer, although Cannondale is stressing the BMX aspect of it more. Having the axles less than a foot off the ground gives it a low center of gravity, which takes some getting used to, but it also feels much more stable for that very reason. I'm glad I got the eight instead of the three because I found myself using the whole range of gears. Only at the highest speeds did the lack of a large front chain ring become noticeable, but this is a bike to be driven more like a sports car than a cross country cruiser anyway.
