I'm having problems attaching a Schwinn child/pet trailer to my RadRunner after using it for several years on a conventional bike.
The coupler (photo 1) won't sit flat because of a bolt located just above the axle. Another coupler (photo 2) fit the axle ok, but didn't have enough space for my trailer arm. A third coupler that misses the bolt above the axle (photo 3) is recessed, so there isn't enough room for the stock axle nut to attach.
I tried to find a conventional nut to attach to the axle and the threads on the ones that were the right size weren't compatible.
My next thought may be to take some metal tubing to connect to another coupler that is too small to attach directly to the trailer hitch. I looked exhaustively fo r another coupler that's slightly larger and fits the axle but to no avail. My thought was to get a smaller-sized tube, attach it to the coupler and attach the other end to the trailer arm and use washers to account for the difference in size between the tube and the trailer arm.
Does anyone have a better solution? Thanks.
