Need Extra Heavy Duty Panniers ...


I am having somebody custom build a Yuba Sweet Curry with an electric motor ....

I need extra heavy-duty panniers that will carry at least 50 pounds each .... Any recommendations ?
I decided to go with the Surly Big Dummy Panniers, which are rated at 60 pounds for each pannier. I will be carrying lots of weight sometimes, so the Big Dummies will come in handy for shopping and camping.
