WOW! What an adrenaline rush!!!
Here's my take on it. It's obviously not a "China Girl" engine so timing and compression has to be better, I'm betting he held on to the car to get up speed then kicked in the motor (you can hear it start up at the beginning of video and I see no pedals on the bike) so its probably geared so high that it would never be functional in stop and go traffic. It appears that the run started on a slight downhill grade and perhaps a good tailwind as well. And of course laying down makes a considerable difference in wind resistance.
But it's still cool if you're into adrenaline rushes like that...woohoo!
I can get 50mph from my bike but it's rare that I can maintain that speed for long on any side street because of stop signs, traffic lights, people pulling out cause they didn't see you coming or thought they had plenty of time because it's just a bicycle (yes, it happens often), hills, etc.
I LOVE the look on peoples faces when they leave me behind at a stoplight and I get to the next one just seconds after they do...
