boneshaker [ˈbəʊnˌʃeɪkə] n
1. an early type of bicycle having solid tires and no springs
2. Slang any decrepit or rickety vehicle
They called it a boneshaker because the seat of the bicycle sat right on the frame and there was no suspension. Top hats and tails, only a fancy man could afford this pleasure ride. Suspension or not this guy does not seem to care.
This skeleton rider is heading South to Mississippi.
