Looking at those videos again the acceleration looks as effortless as it was incredible. I can't remember any footage of even Merckx in his prime riding away from a lowly domestique like that.
I think you should watch back some old footage
Here is another
tv-report (called "Motorrace"
), this time a Belgian show.
There's 3 parts..
Part 1 has an amateur racer using it against (retired) Museeuw. Without engine, the amateur does his best but can't beat Museeuw (on the Kwaremont), the second time with engine he absolutely destroys him.
Part 2 shows how the bike can be made, the Cancellara bit in the RvV and some interviews of e.g. Boonen and the Sporza Commentator
In part 3 the same amateur takes part in an amateur race. He ends in the front group (somewhere during the race he solos to this front group). Aftwerwards, he says using it isn't great (he has to go each time to the end of his steering wheel), but most of all he feels very guilty, he didn't go for the win, but he did e.g. catch someone back in the final lap (who could have won if he hadn't of course).
