I don't think I would trust those flimsy roof bars with the weight of two heavy e-bikes.
The roof bars are not connected to to the 'roof' but to the side pressed major structural sides.
Does anyone really think that a car manufacturer would make both car and accessories in this day and age that cannot reasonably fullfil all the expected uses of the car or indeed be allowed to?
The windage or side centrifugal loads on bikes on the roof will be well and truly calculated a the worst possible condition probably at SF2 at least, get real folks, Honda and no other manufacturer will not make anything that could possibly lead to injury, failure and loss of reputation let alone being sued.
