Gyroscopic action has nothing to do with it, but the placement of the front hub with respect to the projection of the shaft which connects the handlebars to the front wheel is the key factor. A bike can be made so stable that it is tough to shift from its chosen path, or so sensitive that it needs continuous monitoring. I don't know the details, but you could find the reference in an index to Scientific American.
