That's now going to be necessary. It's not hard; my horse vet has a hand-held X-ray machine and a detection plate that connects to a laptop. An electric motor is obvious in X-rays. It would take maybe 5 minutes per bike. You only need to scan the leaders, of course.
Domestiques use other kinds of dope as much, or more than, race leaders. Their job is to burn themselves out in service to their leaders. If you dope up your domestiques, the leader gets an easier ride.
