I thought there was something like this a few years ago too. The
explanation was something to do with the springs storing energy whilst
on the downward power stroke, and releasing it on the upward return
stroke of a normal pedalling action. This helps, the claim went, to
iron out the power impulses inherent from pedalling. I'd guess this
acts a bit like the 'cush drive' in motorcycle rear wheels.

I can't find a link for it now though.
