Hey Mike.
For that specific design, yeah, I can see why 300 lbs would be heavy. It lacks cross bracing between the wheels, or anywhere except that arch and the "body." There are no structural triangles, and no uprights transferring your weight directly to the wheels.
I don't see the advantage to the design. Besides, as a larger-framed person myself, I don't know how I'd feel sitting inside one of these contraptions. When the wheels spread under weight, wouldn't the whole thing collapse on you?
