fietsbob

I have a Brompton , and a carry freedom city trailer. a beautiful combination.
both fold, and the trailer does not prevent the rear fold
from taking place on the bike, it's kickstand.
I can carry that bike , folded up, on that trailer.

Bike Friday uses a High pressure air powered tool hose quick connection .

for their trailer hitch .. ran lots of those tools in the shipyard..


would be easy to make a mount for one in most any welding shop,
to fit your bike.
