To cross that lake on a bicycle you'd need a fatbike and you'd need to steadily apply about 15,000 watts by my estimation.

Well I like my body parts in their current configuration, so I'm not going to demonstrate it personally, but video evidence exists.

You Tube

If one pays attention to those videos, in addition to the several crashes resulting from hydroplaning, one can see some outstanding bikehandling where the bike is wiggling around underneath the rider due to hydroplaning, yet they manage to stay upright.

If that's how you are defining "hydroplaning", then it is no wonder you are so confused.

^ none of that is hydroplaning.

None of those are hydroplaning. Those are demonstrations of losing traction. This is why you are the lone soul proclaiming in the darkness.

Words have definitions. You sir, are wrong. Just wrong. Hence the opposition to your claims and the efforts to change your understanding of the word.

...And you call us "anti-science?" Go. Run the experiment. If you can irrefutably demonstrate you can plane a bicycle upon the hydro such as the water skier, or snowmobile in the other thread we will all yield the position.

But your argument appears to be complete nonsense that nobody is buying into.

How -- exactly? How, exactly, does one "lose traction"? Before answering, remember how traction is generated by a rubber tire. Since most here do not know, I will explain. A rubber tire generates traction when the force of gravity acting on its mass, and the mass of whatever it is supporting, presses it into the surface on which it is rolling ( or sitting ), and the rubber deforms into the imperfections in that surface. The resulting interlocked interface between tire and surface is what we call "traction".

So, again, what exactly occurs to disable the force of gravity acting on those poor riders' tires?

Obviously, nothing disables gravity. What we see occurring in those videos is that water fills-in those imperfections in the road surface, and since water is incompressible, the tire rubber no longer has imperfections with which to mate, and no traction can result.

And that, is hydroplaning.


Yes, I know -- I just had to quote you the definition of the word we are discussing, since you were seemingly unaware of it.

I just did -- or more precisely, those riders and cameramen in the above videos did. I'm just the messenger.

In the first clip, he hit that dip in the road so hard it damn near instantly knocked him off the bike! Once you get that far out of balance and have both feet unclipped, you're likely to eventually come off the bike as he did.

Nobody... other than every tiremaker who builds treaded tires, of course. And the one individual a few pages ago who experienced hydroplaning on a bicycle.

Clearly I was laughing at my 06/23 self for imagining that you might have left so easily. Now that you are cranked up again I'll be watching to see if any of your bizarre discussions convince anyone of anything. This is not the first rodeo and I think you'll find that many people here actually do cycle and know a fair amount about it. But don't let that stop you....

He says I could do it on my 700 x 23s if I was going over 120 mph. I admit I can't pedal that fast.

TC1

That's a world-championships-qualifying rider. It's not the first time he rode over a bump. These guys do not very often crash alone, riding in a straight line, on a course they reconnoitered. It's pretty desperate to convince yourself that he wiped out over a little bump.

LesterOfPuppets

Happens all the time.

TC1

Some women can ride half-again that fast. The point is, many people here are confusing the question. The question is not "Can I hydroplane my bicycle via my pedal power?" The question is not "Can I ride my bicycle across an entire lake?" The question is not "Well I've never hydroplaned, so I guess it must be impossible?"

The question is, are bicycle tires somehow immune to hydroplaning at all speeds, as is often claimed on this forum?

And the answer is, "No, they are not." And we have both mathematical and video evidence to support that answer.

More precisely, and of direct concern to most riders, is "Can I crash my bicycle due to hydroplaning?" And that answer is, if you approach the hydroplane speed -- the formula for which has been mentioned repeatedly and known for 60 years -- by any means ( gravity, electricity, human power, magic, etc ) -- then "Yes, you can suffer a hydroplane incident."

There should not really be any debate about that, at this point, but those resistant to science will apparently persist for a while longer.

Note the word "alone" in the comment to which you replied.

PeteHski

None of my road bike tyres are treaded and they don’t aquaplane.

That one individual didn’t really seem to have much idea about what happened, but since he didn’t actually crash and probably wasn’t going at warp speed I very much doubt it was aquaplaning.
