I did cheat with my photos and use a Canon EOS 1D. It has incredibly fast focusing, virtually no shutter lag, a real viewfinder, 8fps/21frame buffer and a real fast lens. I also have a Canon S50 that I bike with and I took some photos with a friend of mine when we were riding and I did use the continiuous mode and it did well.
Here is the result with the S50 and contiuous drive mode.
The prices and quality of DSLR's is coming down a lot. The new Canon 10D is a lot of camera for the money if you can live with the 1.6 focus multiplier. The best part is they keep getting better and cheaper. I use
