Erik, Do a search for Win van Wijnen's Ecocar 2000, a centre steer bike, with a virtual pivot axis passing through the rider, with actual hinges above and below. I doubt if balancing has anything to do with placing the hinge below the rider: it's all about construction. Can you explain your direct drive? It looks a bit like Robert Waryszak's Python Militaire, but what I take to be a cluster is very close to the driven wheel.
