Sure, there are plenty of references that make the theoretical claim

Umm,... Timoshenko showed that gyroscopic forces were essentially irrelevant.
I was confirming your point, but identifying earlier analyses exist than
Jones. I wouldn't be surprised if Jones referenced Timoshenko. It's a
classic text in mechanical engineering. Whitt and Wilson's book on bicycling
science also catalogued many studies on bicycle stability done before WWII.
