I built this stand about three years ago for a motorcycle project I was working on. I'm on to the next thing and need to clear space in the garage. You can see by the pictures that I've installed a PitBull wheel chock and removable PitBull tie-downs. There is a ton of storage underneath and 6 heavy-duty (lockable) castors to move it easily around. The ring on the end is used to keep your ramp secure when loading/unloading.
Not gonna lie, I overbuilt the hell out of this. I've had a large motorcycle and two adults on top, and it didn't break a sweat.
