What is an alternative hitch for the Re~Cycled bike trailer? What is an alternative trailer hitch for the Re~Cycled bike trailer?  This is the webpage of the trailer http://www.re-cycle.org/sites/re-cycle.org/files/Trailer.pdf

The reason I don't like it is because it tends to spring open and closed. Maybe use a ball and rod like this?
Simplest answer would be to find a trailer that you like that sells the hitch as a spare part, and use that.
