I rebrowsed some of the thread to make sure I was superficially up to date.
The question I would have :
There's been at least a couple of amateurs (or semi pro ?), one male and one female from my recollection, that have been busted for rigging their bike with a motor.
Do we have more documents of what it looked like and / or tests to assess how effective (if any) those garage jobs were ?
If it's already been addressed, I'd be glad to follow a link to relevant posts.
Lemond was on a podcast recently and said he believes many wins in the early-mid 2010's were achieved with motors. he said didn't want to get into "specifics" but he said former riders personally told him that they knew of riders on their own teams using motors and then he actually specifically mentioned Froome on the Ventoux as one performance that stands out to him as being suspicious for a motor.
