Cargo And Bike Carrier
Quite a while back, someone had asked for dimensions of the rack that I had designed and fabricated for the AI. I'm sorry it took so long, but for nine months per year our state is a dark, cold, and forbidding place, where hope fades and dreams die. Mortal souls never venture outdoors where the ice, snow, gloom, wind, salt, and cold menacingly await to consume the weak and unwary.
Anywho, I wanted a way to bring as many bikes as possible and have a little extra storage with the AI without resorting to a trailer. This is as large a cargo carrier as I think is practicable. Anything larger should necessitate the use of a trailer.
I made a crude drawing with the dimensions and had a local jobshop weld it up. I had another shop sandblast and powdercoat it. It is made of steel (sorry, I don't know the specification) rather than aluminum. I thought there would be too much flexure with aluminum.
The trade-off here is that the back doors only open slightly. That is fine with us; we store less-frequently used items under the lounge: Awning lever, curling brooms, hiking sticks, headrests, etc. I am still able to reach the hot water shut-off.
Someone asked if we noticed excessive swaying with this arrangement; we do not experience any more sway than than an AI usually has.
Of course, there are limitations to how much weight you put on the trailer hitch. The AI has a 500 lb. tongue weight. The further out you extend an attachment like this, the lower the weight should be that you put on the tongue. I calculated that we have less than 250 lbs. with the apparatus fully loaded. We are able to load the tandem, the steel fat bike, and the carbon fiber road bike.
By the way, 1UP-USA makes the best bike racks that I have found.
