updated hitch for a Yuba Mundo v3 and the Bikes-at-Work trailer
This is update to the original design we tried. The hitch needed to be moved further rear so that it doesn't interfere with the running boards.
Some details: the hitch tilts slightly downward to match the angle that the trailer arm connects with. Also, support brace needs to be recessed back just a bit. Otherwise, as the bike tips forward, the hitch support arm will strike the bottom edge of the trailer arm.
Testing of this design has not extensive, but has worked well so far.
