So you think the regeneration actually works by clamping the rear brakes? For some reason I was thinking there was another mechanism within the hub that engages when coasting (and this is the 'faint hiss' you hear along with the slight drag) and the rotation of said mechanism is what recharges the battery. I'm having a hard time visualizing how applying brakes to the rotor generates the juice.
