That a newb should understand a fraction of this stuff. The thread is a learning experience though. Glad to be here, joined today.

2 facets of the same myth:
Big puffy saddles are ALWAYS more comfortable

Or

Serious road bikers wear padded shorts to make up for cushion on their saddles

Fact is, road bike saddles are supportive in all the right areas... that's why they're so personal. what fits my butt won't necessarily fit yours. A chamois supplements that, but isn't "making up for lack of padding."

please explain why bikes don't hydroplane
Because bicycles have very small contact patches. You can lose traction very easily because of this, but hydroplaning would require unrealistic speeds, above 65mph.

Exactly. Wet pavement doesn't provide as much traction as dry pavement, and painted lines, metal plates and manhole covers can be quite slippery when wet, but you aren't going to skip across a big puddle at cycling speeds. Someone should try it with a fat bike and a car towing them up to speed.

Bikes don't hydroplane for two reasons:

1) They don't have a large enough contact patch to hydroplane.

2) They don't go fast enough to hydroplane.

They skid instead.
Not the same thing. IOW, directional tires that are designed to channel water away from the center won't make a difference like they do with cars.

Could you really not look this up yourself? Here's the formula: Vp = 10.2 sqrt(P) Vp is hydroplaning speed in mph, and P is pressure in psi. So for a bike tire at 100 psi, hydroplaning starts at 102 mph. At 49 psi, hydroplaning starts at 71.4 mph. Amazing what you can learn when you actually choose to.

And this ain't no myth.

Minor correction to your formula: Vp = 10.2 sqrt(P) ... should be Vp = 10.2 squirt(P) because, like, hydroplaning makes water squirt. See?
