DemiBike Recumbent Unicycle

I want a one wheeled "bike" like this. The layout is inspired by Charles F. Taylor's one wheeled vehicles - a central wheel that you sit behind, with a nose counterweight.

With battery electric propulsion, the battery pack is the nose counterweight. Nylon rollers at the front and rear limit tilt during hard braking or acceleration.

It's not clear what this sort of one wheeled vehicle should be called. A unicycle implies that you ride above the wheel, while a monocycle implies that you ride within the wheel. In this vehicle, you ride behind the wheel, with a counterweight in front of the wheel.
