Care to elucidate? A watt is a watt and a Newton meter is a Newton meter, whether first, last or somewhere in between. The physical effort a cyclist requires to put out 900 watts at a certain cadance will not be affected by motor assistance.
A watt is a watt. If a mechanism exists to deliver 100 watts, be light and relatively undetectable it has limitations on the torque it will deliver. My point is the first 100 watts of effort is relatively low torque. When you are at 700 watts of output,
in an environment with wind/cobbles, etc; how would such a light system assist at that output level? It couldn't simply add 100 watts to the effort as it would have to apply the output to the rider's variable torque and rpms.
Boardman weighed in with the theory that Formula KERS systems could provide renewable power, etc. You still have to transmit the power and that's where, while possible; it's not going to be that stealthy. Add to that this quote from Boardman:
"My experience within the sport tells me that to cheat blatantly in such a way would be such a massive step for those concerned - and it would involve so many members of the backup team and staff - that although it is possible it probably hasn't taken place yet for real. Just because you 'can' doesn't mean to say you 'do'."
If the UCI is really concerned you have the bikes file through an Ultrasound checkpoint at the start and submit any rooftop backup bikes to the same scrutiny.
Do I believe someone would attempt to cheat? Sure.
