Interesting theory. I think the cost (weight) would outweigh the benefit though, even if it were possible.

First off, a motor would not last very long to be able to put out the kind of power and torque required to give a "boost". While one certainly could be built that might do SOMETHING and give SOME kind of advantage for a few seconds perhaps (yes, this could make a difference in a race) you have to remember that the rider is lugging the weight of this device around for the rest of the stage.

If a rider can lug something that heavy around with them for the whole race until a critical moment and still be out near the front or positioned for an attack where they might actually realize some benefit from it, then that person is probably strong enough to win without it.

There are road guys who are AMATEURS who get into counting grams on their bikes. A motor and batteries are going to represent a lot of weight considering that a few grams is enough to make a competitive difference one way or the other for world class riders.

Interesting theory, but I think those guys need tin-foil bike helmets.
