First of all, "scholarly" is not the only type of evidence. Quite a lot of professional research has occurred on this topic in the past 60 years, as no one should be surprised to learn.

And, again, we have video evidence of cycles hydroplaning -- which is the 800 pound gorilla in this particular room, who remains ignored.

I am still waiting for someone to explain how those bikes hydroplaned, if such is impossible. You have only three choices:

1. Insist that all of those videos were doctored
2. Explain the other as-yet-unknown phenomenon which caused the separation of tires and road, and which allowed that motorcycle to travel across a lake
3. Admit the obvious, which is that bicycles can and do hydroplane
