I tried posting a picture of each wheel but I guess this forum wont let me unless I make 10 posts. Its 183 pounds on the back wheel and 65 pounds on the front.

I did not measure a triangular frame but I would assume that front bar would help it spread out more evenly. As such, a triangular frame would likely have better weight distribution and reliability as far as spoke breakage goes.
