I'm just using the top platform at this point. For that it's been incredibly stable. For instance the mount to the fork-top brake hole isn't a thin piece of sheet steel but a fabricated piece of real steel that's stiff. I like that the weight rests on the fork end. Most of the lowriders I've seen don't use the fork middle mounts for anything but stabilization, not weight, and don't do that job well at all, but this one skips that problem entirely.
