sweet ute. i just got done building a utilitarian cruiser myself, works great but i gotta get some picts of it. i went with the old milkcrate attatched atop a rear rack with a quick release type basket up front. i can put in 25lbs in back, prob more once i reinforce the mounts, and about 15 up front. cool thing is, when i don't use the front basket, it comes off in seconds and fits perfectly in the rear basket (kinda like what logging trucks do with their traillers when empty). single speed so i geared it low at 36/20.
not nearly as nice as yours, but these cycle trucks can be fun and work very well. mine is more like a redneck rat.
