I can use either of my 2 wheel trailers by just putting either ones tow fitting under the left axle nut.
But I prefer the Chariot hitch on my Carry Freedom City, because it's elastomer on the trailer is a Ball.
so the rear wheel fold / kickstand functions as usual, rotating around it's pivot, and the ball within it's socket.
Added benefit ,, the CF-C, with its sling bag in place will take the folded up bike laid on top of it, *
then, trailer itself will fold flat, wheels within it's frame , once the bag is unclipped.
* then say run with it to a seat in a car on the other end of the train station platform,
or tow, carefully, up stairs .
the Burly Travoy as it fits to the seatpost should work well .. as well .
Paddle shaped elastomer and the inverted F style forged hitch of Burly's 2 wheel trailer
with a pin through both to pivot R/L. works fine. elastomer flexes when you lean into a corner..
