Here's my bike:

I average 14-16 mph on the flats with my Kona. It is much faster than my old (and long gone) mtb and my recumbent (which I sold, too). On my Trek road bike I averaged 18 mph or so on the flats.
The Kona wheels are wide to hold some pretty wide tires (1 3/8 inch). I ride on gravel, grass, and asphalt. I ride through potholes and glass. I inevitably steer TOWARD shiney objects and run over them!
I'm very happy with my Kona hybrid/cyclocross/commuter. It's perfect for the purposes i bought it for. (general riding and commuting on a variety of surfaces)
