Yes, it does happen. In fact, it __must__ happen, unless you have an alternate explanation for why the interlocking between the rubber and the road ceases. Do you have such an explanation, sir?
As long as the rider is still aboard the bicycle, and as long as the bicycle still has a mass, gravity must necessarily still pull them both into the Earth. So unless your tire pressure somehow skyrockets while you are riding, then your tires are still going to interface with the road until and unless something separates them.

Again, why is the coefficient of static friction less?
That's the point you are missing. Hydroplaning can be a motorcycle across a lake. It can also be a microscopic layer of liquid -- technically only one molecule of depth is required -- which is not even visible to the naked eye. But the physics remain the same, due to the incompressibility.
Again, there is nothing else which can cause the reduction of friction -- unless you are proposing that the rider and bike have their combined mass drastically reduced while in motion, which is a radical suggestion, to say the least. Or perhaps you believe that gravity fails, every once in a while.
