Porteur bikes are hip , and cargo bikes , and single bikes in length .. the cargo is carried on a big front platform rack

made solidly fitted to the fork (French Style) or a forward extension of the Frame (Dutch style)..

Builder Human Powered Machines in Eugene offers a front frame basket support in their version of the Swift, a 2x20" wheel folding bike,

which uses the seatpost removal to do the fold. http://www.catoregon.org/
