The Dummy rides well and I don't notice any squishy-ness in the rear disc. It rides the same with 60lb carpet cleaner on one side and nothing on the other. I hauled an old Schwinn back from the LBS with the tire in the front tire in the freeloader and it worked flaulessly.

I am still working on the best posture and handlebar choice. I may go with some retro cruiser bars soon.
