Hey Ashley, I'm assuming that a bag will work. Yakmia told me on the phone that it was only meant for bike and snowboards I think. Didn't mention bags, but I'm guessing that will work. I know rationally the bag makes more sense, cheaper, easier to store, etc I just prefer the cargo carrier as it looks cooler. Kinda like the VX, there are TONS of SUV's that make much more sense, but it looks so cool!
