Here is the rack, without bags. The bags should remove at the press of a button, but there is a tolerance problem somewhere. I have to open the bag and press the release from inside the bag to remove them. Not a big deal, but something I'll fix in the next week or so. Notice the large knob above the rack, next to the seat. This is the optional locking knob that keeps the racks from being quick-released by persons unknown in the dark of the night. The knob comes off with the racks.
