A close up of the front seat reclining adjustment. The red, vertical tube tilts back and forth, and the chrome tube sleeved down into it telescopes to allow the seat to tilt forward or back. A quick release seatpost bolt tightens the tubes to fix the recline angle in place. The seat frame and cover are from the now defunct Vision recumbent bike factory. They goofed on the design for the slotted tangs that come out the back of the seat frame. The tangs should have been curved to allow for the arc of the seat to pivot, so the slotted tangs are useless. The back seat frame has arc'd tangs, and they work well.
