Is there a trick for removing the seat (helmet) lock assembly from the frame? I can see the threaded portion of the two bolts on the inside of the frame, but there is no bolt head on the outside. I'm assuming these are some sort of security bolts. Any pointers for getting it off the frame? Thanks.
Break-off bolts. Get some small, fresh vise grips to get on the edge. They usually let go easily. If not, dremel a flat blade slot.
