Which is why physicists and mechanical engineers have been analyzing and 
attempting to perfect the bicycle and cycling technique for decades - 
because there's nothing technical about it, right, dumbass?

Nice strawman. Didja have to work on that for a while? Sounds more like 
butt-hurt whining to me.

What a fragile ego you have! Ironically coming from someone who's sole 
purpose in this forum is to insult an denigrate someone else.

And here's the proof in the pudding. You have no understanding of the 
difference between a fact and an opinion. A mathematical analysis is 
fact, not opinion, dumbass.

Yes. If you didn't you wouldn't keep posting to _try_ to make yourself 
look less stupid (and failing miserably)
