Now, I have not yet hauled 100 lbs. of weight to match my body weight (but I know Eden did).

I just bike with 2 rear panniers when grocery shopping. At times, the grocery weight is heavy enough that there are times I wonder if I will get a flat tire or warp my bike frame as I bike along homeward. During summer, I'm piling in local fruits and veggies.

Occasionally at times to be safe, I find I have to get off the bike to make a sharp left turn. I just don't feel safe enough without the feeling I'll fall over from the rear weight.
