Editor’s Note: I have been asked to remove the links, and I have.
No, I have no idea if this bike-actuated dildo is an actual product or the brainchild of a single, horny inventor (I strongly suspect the latter), but either way this contraption can take one lucky rider on the most memorable joyride of his or her life. Be warned, the other pictures are definitely not safe for work, anyone under 18, or those scandalized by the direct intersection of human anatomy and chain-driven machinery.
