This thread is for those who aren't comfortable or just don't like the standard tow ball and cup hitch for their bike trailers.
Having had a trailer roll completely on to its lid whilst being towed by a motorcycle, I am one of those people.
It is designed more for the light trailers but could be made beefier if your tow a heavier trailer such as a camper.
FYI A lot of outback campers in Australia run similar systems.
Start with a piece of flat steel and some steel tubing plus two 10mm galvanised bolts plus nuts and split pins
Mine are 25mm x 3mm and 25mm dia tube.
I have not mentioned specific dimensions as they will vary according to how big or small you want to make it.
Cut in to pieces like so.
Loosely assembled pre-welding
Welded and had a lick of paint.
I have welded a square plate on the front because my coupling is recessed in to my drawbar.
The two nuts welded to the side of the tube are so it can be bolted in from the underneath of my drawbar.
Quite often I have seen the tube just welded to a steel plate which is either bolted or welded to the drawbar.
Purely up to you how you do it. This is just o give you guys some ideas.
