Of course motor doping is in use, it was even in use back in 2010 with cancellara and breschel, breschel who was fuming after flanders since he got the wrong spare bike, the same race where cancellara litteraly motored away from boonen (go figure). Also Sky was notorius for motor usage, just watch Poels here motoring away up the Angliru lol.

Also 2013, especially with Froome up ventoux with the leaked watt files, its clear as day he is using a motor, you can also see it from the spectators view its so stupid.

Foliforovs famous tt in the giro, also ebike.
Roglic had motor in the bike at Strade Bianche a few years back as the infrared spectator cam found out.
Now many top teams have it, you have to adapt or die out, as such sky/ineos dominance is more or less over as other teams have leveled the playing field.
Lets face it UCI has no interest in catching any of these guys, as with the useless ipad scam app. Spectators should set up ir cams during mountain stages on the roadside, i would guarante the bikes would glow. You would have to be emotionaly invested to belive otherwise.
