It's one of those things where I'm like, dang, I sure wish I had one of those. But I don't want to actually ride it most of the time, just have it.

The one pictured has an estimated cargo capacity of 60 lbs or so, which is similar to many light trailers. Unless you use it all the time as a work bike, you'd probably be better off just hooking up a trailer when you need it.

These guys use it all the time.
