Step 5Hitch (bicycle side)
The hitch is attached to the rear axle of the bicycle; I put it on the side away from the derailleur, to make that side less congested. For the mounting bracket, I found that a Unistrut P2109 bracket works pretty well--plus I had it around the lab. It requires threading the other end of the air hose quick connect into one side of it. Fortunately, a 3/8" NPT hose requires a 9/16" hole, which is what the fitting is already drilled at. Win!
The first connection strategy was to use the existing hole, and connect it to the quick-connect on the rear wheel. However, that didn't work: the weight of the trailer pulls down on the hitch, and it rotates downward. Grr.
Therefore, I added a bolt and additional hole to stop the rotation; had to drill another hole for the quick release skewer at the axle. You have to line everything up first to make it, and then drill the hole. A quick release skewer only needs a small hole (~1/4" or less).
