Thermite is awesome. The site I used to make this from youtube sucks.

No, I get it; I see how it works. It just seems like there is a lot of momentum-killing back-and-forth with the bike.
If you look at it like he is creating his initial momentum (energy) with the jump then trades some of his energy in his body to the bike (overall energy stays the same) to allow it to get ahead of his body, it think it makes it seem a bit more reasonable. The center of the mass of him and the bike will still move the same distance either way he just rearranged where the bike was in relation to it.

The neat thing is, you can use the bike as a lever and jump higher than you ordinarily could. I remember years back there was a bunnyhop (vertical jump) competition and most people were over six feet, with the winner at something like six foot seven.
The highest I could ever bunnyhop was three feet. I could go higher with clipless pedals, which is cheating, but cheaters never perspire.
