I'll post what I think is the link you're looking for:
Images of Cargo Bicycles, Cargo Bikes, Utility Bikes, Cargo Utility Bike, Carrying two kids by bike
These are utility/cargo bikes, kind of like a stretch cruiser, except more like a truck. There might be some chain clearance issues around the bag support arms in the back, but I'm sure it's something that can be overcome. It's the perfect idea, though, a little cargo MB.
Edit: Mmmm, another look, the frame looks pretty tight for an engine mount. Would probably need an offset intake at least. I still like the idea.
Where at in IL? I'm in Kendall county.
