In motorsport the vehicles are inspected thoroughly and then a seal is placed on there. For instance on the engine cylinder head a metal tag is placed on the bolts to ensure that the engine has not been dismantled throughout the season.
This method of checking looks like it could be subverted by some teams.
Or simply taking the time to remove the bottom bracket where the drive shaft would be.
Which is what they did to Van den Driessche's bike after the iPad gave suspicious readings, and apparnetly they had trouble dismantelling it.
As an initial check, its far too time consuming to do this to a selection of bikes prior to racing.
Very high tech looking, but not likely to be any more effective than tapping the tubes and listening for hollow noises, or lack of them. Or simply sticking a magnet on the frame and watching if it falls off (unless anyone at testing level is still riding alloy frames?).
Not all motors have magnets.

I think that eventually they'll have to x-ray bikes.
