Tilting Delta Tricycle - A crazy concept for a delta-configuration tricycle with the capability to tilt. It does so through the pivoting action of the rear forks, linked to the steering column with cables (not shown currently).
There is a differential to ensure traction and control, and it drives the outer drive gears. In this setup, those gears are larger than the differential, creating a much higher gear ratio from the crankset to the wheel hubs.
