My 2nd trailer is a carry-feedom-city,
It folds flat , and the wheels are far enough back
to pull around by the handle..
as the mount is a lollypop elastomer . it lets the Rear end of the Brompton fold under
with out un hitching. the sling bag in the frame will also support the folded up Brommy.
so the chase down the train platform can be at a Run.
