Not only will it easily take that weight, it's designed to comfortably carry a passenger and cargo. Or the Yuba Mundo, there are a few other brands. And you can get them in electric, if your thighs aren't made of steel cable.

Yuba Mundo is $1800, which sounds like a lot, but with inflation that's well under a grand at the time when more bikes were heavy and over-engineered. With the nice side effect that they could carry a lot of weight....
