Weld,
I'll have to take a photo of the mount on my DF but here is the site where I bought the trailer eight years ago. Photos of the mount there and attached.
It has been use on about five different of my motorcycles/scooters. Now has the pit bike wheels but I never had a failure with the BMX bicycle tires.
Real handy for hauling but use at your own risk. Might poke your eye out.
The canvas on the trailer is getting a little ragged but still going good.
