My wife just got a Liv Thrive E bike and we ran into the same issue. It never crossed my mind the fenders would be an issue with the Kuat rack. I just put the arm carefully over the fender and hoped it would hold it securely without damaging the fender. We got home with it and everything was fine but I am still looking for a better solution. Maybe slide some type of firm foam under the fender on top of the tire and another on top of the fender. Anyone have any better ideas? She does not want to give up the fenders.
