Smart concept and it seems to work quite well.
My only concern is the rolling resistance: even on a perfectly flat road, the springs will flex continuously, like a tyre actually.

A good suspension combines flexibility and damping (to prevent continuous bouncing), but adding more damping to this system will inevitably increase the rolling resistance :confused:
