A tyre aquaplanes at 9X sq root of the pressure. So an S at 55mph or so, and my bike (45psi ish) 60mph. Obviously has to be standing water! My push bike, 120 psi, 98mph! Better get peddling!

As a bike has a very small contact patch the pressure between the road and the tyre is high and therefore the speed at which you would aquaplane will be very high.
I would expect it to be well in excess of 200MPh

No, its the tyre pressure, which is the same as the pressure on the road.

We did this subject a few months back.
EDIT: Hydroplaning from Wiki
The formula you quote above relates to aeroplanes when a plane comes into land i.e. it is not on the ground and therfore exerts no pressure on the ground.
