I have a trailer and occasionally I will use it to transport stuff to work or to get groceries. When I use the trailer, I always feel a bit macho. Imagine me speaking in my best neanderthal voice, "Me Man! Me Transport heavy objects with own strength. Me Macho!"
In reality I am anything but macho since I probably transport like 40 or 50 pounds and I don't do it daily. Reader David on the other hand is Macho. He transports several hundred pounds, every day. If you think you are macho, let us know. Take it away David . . .

I made a cargo bike for delivering newspapers (200 to 300 daily). I have what is called a single-copy route which means I fill vending boxes and stores as opposed to delivering individual homes. It is two mountain bike frames put together with aluminum frames that fold out to hold the side containers. When not in use, the tubs all stack in the center tub and the side frames fold down.
This bike is much faster that the trailer set up I was using before I built this as I can cruise at normal bike speeds (15 to 20 mph) The whole thing with tubs only weighs 51 lbs and can haul up to 200 lbs easily.
