There is also no such thing as a tiny silent ebike motor -- the only way to produce a useful amount of torque with a very-small motor is to have it be a high-RPM motor with reduction gears that make plenty of noise.
Crystalyte gearless hubs can provide almost 2000 watts of power and can do it quietly too. But that's because they are big heavy hunks of metal.
There is no such thing on the shelf of the LBS to be sure but if you have the time and money there is no reason such a thing cannot be built.
Gear noise is a product of mass production and sloppy tolerances. Given a dedicated machine shop and exotic materials such as delrin or ptfe doped ceramics you can make a gear set as silent as you want it to be.
With the amount of money riding on the outcome of the pro racing circuit I think such things are not out of the question. I do wonder where the heck they would put the batteries.
