Various theoretical methods include moment of inertia in various axis and simple center of gravity measurements.
Hmm... moment of inertia and CG measurements indicate that dude's crank is a couple kilos heavier than everyone else crank.
If carbon fiber is RF transparent enough then low level microwave radiation tends to react interestingly with semiconductor junctions.
After EMP sensitive gear (if any) were removed from the bike, old fashioned microwave RF zorching or fancier "real EMP" could make the issue moot. Once the electronics and wiring are blown, a motor is just an expensive piece of ballast.
The last technological way I can think of is a careful magnetic analysis of the bike.
I would imagine a very permanent long term solution would be a careful stress analysis and small holes drilled into all frames for a COTS borehole camera.
