It was alleged, that the bike with the motor, was not her bike but a friend's bike, that was left in their tent, and mistaken to be the althlete's bike. But also supports your statement, if this wasn't the athlete's bike, why go through the effort to hide the switch or mechanism at all if you're not competing?
On the flip side, if the bike was actually a friend's bike, what do you say to that friend that got you banned?
