What you don't get from these videos is the low frequency roar of the bikes as the pass by. I'm not sure if that is from the air or the tires, but that's one of the things that makes them sound like a jet fighter to me! Until somebody gets some good audio equipment out there to record that sound, the only way to experience it is to be there.
If anybody asks me if I miss the ear shattering noise coming from the ICE bikes, I can emphatically say "Not for a second!" The sounds coming from the electric bikes was a lot more impressive to me, since that was the sound of everything that the ICE would block out.
