Hmmm...I wonder how easily one could fold and trolley around a Brompton with one of these custom racks:
I know vik has strapped some rather huge loads to his tikit, but you can't take it all inside like this:
However, given how easily I've found a folded Brompton can tip over, even while unloaded, I don't expect this to be as much of a solution as the pictures might suggest. Anyone care to comment on just how well a Brompton could perform as a handtruck/trolley?
