The winner to our quiz was Hagen who correctly answered:

“… in reverse order (that’s the key to figuring it out)
#3 little tripod mount attached to the rear wheel hub, a panier frame and perhaps the seat post (or another spot on the panier frame).
#2 f16 based on star burst, distance from focal point and depth of field
#1 either 1/30 or 1/15s for bike motion and exposure with the sun directly in the frame.”

Nice work!
