To reply to the following quoted message: "Thanks. Part of the issue is that there is a distinction between "ride" and "use". By the UCI's definition, putting the bike in the pit is "use" even though she may not have ridden it during that race. Do you interpret the UCI's claim to be that she started with the motorized bike, rode it part of the way through the lap, and then switched to a legal bike?"

The UCI never made any claim that she rode it, and I don't think they will do so either. My interpretation is that they find that a moot point and simply find the uncovering of a motorized bike to be unacceptable.
