This means that the front wheel of the bike doesn't lift - the load is evenly supported by the rear wheel of the bike, and the trailer wheel. With your hinge that far back, there is a lot of leverage trying to pivot the bike about the rear wheel, and lift the front wheel.
Good luck finding a solution.
I understand what you mean about the ridgity rbrian. I have since had a bit of a redesign and had a mate weld it up. Since this was done only yesterday I haven't had time to fully test it but right off the bat I found a flaw?
When turning - When the bike is turning (while walking with bike) at a sharpish angle the whole trailer drops to the ground and topples over? - This is a bit hard to explain without seeing what's happening.
I'll try and get a few photo's taken to let you see and better understand.

Just came across this amazing homemade trailer. If any of you are about to embark on making a single wheeled trailer take a look at this one - Nicely constructed, and is one of the best looking trailers iv'e seen.
