Hello,
Yes there are several racks available that will handle recumbents. I use a Hollywood rack with longer extension arms to handle my long wheel base bikes. A short wheel base may actually fit on a standard mountain bike type rack. Do a Google search on "Recumbent bike racks" and you will have many hits.
Also Google recumbent dealers and you will find a good selection.
I use the hitch type mount with wheel loops that are adjustable to the wheel base of the bike. In the
center there is a arm that slides down to secure the frame of the bike.
Good Luck,
Rich............
