I lost a shock bolt on my Moby when I was dropping a rent check off at the office like 8miles from my apartment when I was in college. I found a stick on the side of the road and jammed that in there then ride home standing on the buddy pegs that were mounted to the rear axle.
I rode my Hercules to work exactly once. It was just over 20 miles 1 way. On my way home just before 9pm I blew my headlight (sealed). Stopped at the auto parts store up the road from my office, bought a flashlight, and taped that to the bars. As I was pulling out of the parking lot my throttle cable snapped at the twist grip. I pulled the split ring off my keys and tied the cable to the ring and rode home with essentially no lights and a hand pull throttle.
