Can't comment on that brand, I have a Contour...but here's some thoughts.
I brought my camera for Snow Skiing primarily, but have used it on my bike. Two features I'd look for if I was to buy a camera just for my bike.
1) Remote control functionality of some sort. Depending on where you mount it rear or up front, it would be nice to not have to stop to turn the camera on or off.
2) Support for external mic. When mounting the camera up front you get a lot of wind noise versus engine / exhaust music. Mounting the camera in the rear is nice. Ideally an external mic would solve that.
Few cameras support these, I think a new contour support external mics....but that would be at the top of my list.
