I did not want to buy a $250 44lb hitch
adapter just to carry bikes. Too heavy, so I made my own 11 lb adapter. It's definitely strong enough to tow a light trailer
less than 500lbs, maybe more, but I don't plan to do that.
It's a 10x10x3/16 plate cut a bit and welded to an unfinished 1-1/4 hitch
receiver from amazon. Total cost was less than $100 not including my time and a few scrounged nuts and self taping screws.
It transmits longitudinal, lateral, vertical and left right roll torque loads through the bumper. Longitudinal is limited by the two small 1/4" bolts and 18 self taping screws through the bumper.
The vertical pitch torque load is greatly assisted by a short link to the engine/transmission anti-torque bolt that has a 10mm thread, and 14mm nut and bolt head.
Side to side torque is greatly assisted by a link to the Dedion bolt on the left side, 12mm thread, 17mm nut and bolt head.
Installation is much trickier and requires special tools including an angle drill, and safety goggles. I got branded on the chest by a falling sliver of drill droppings.
Attached to it is a 30 lb 1upusa bike rack that works great! Notice the load test. I actually jumped up and down so it's good to about 300 lb vertical load. It felt totally rigid.
