Got rid of My Yak, as a utility trailer it was unsatisfactory ,
too tall a load and it Torqued the rear of the bike..

Got a Burly Flat Bed , newer ones have the tongue fold down,
older ones the tongue tube is bolted solid.

then I got the Carry Freedom city to go with my Brompton
Folding trailer, folding bike..
The load area in the flat bed takes the folded up city trailer ,
so 2 in 1 storage.
