I mean, TANSTAAFL, right? Does this store some energy when you slow down to release it when you start up again? That would somewhat flatten the energy expenditure curve, which may be a bit more efficient. It would imply that lifting the wheel after you've stopped releases that amount of energy (it seems to do so).

Notice, however, that the springs are actually missing when they show this in the video! Couple that with the fact that he rotates the wheel by hand to a certain position before setting it down, and its evident that the rotation we see is just due to a very imbalanced wheel.
