A few years ago I bought a tandem bicycle, and immediately I thought “What if I took off the back seat and put the back half of a horse there instead? It would look like a centaur was riding the bike!”
A year or so later, I finally got around to doing it. I made a video documenting the entire process, which you can watch by clickin’ that button below.
Also, apologies for the poor quality of the main photo. I didn’t think to get a still photo of the final bike with me on it, so this had to be taken from a video.
