Design group Original Content London pulled inspiration from Monty Python’s coconut-thumping squire and came up with Trotify. It’s a mechanism that attaches to the front wheel of any bike and bangs two coconuts together in a rhythmic fashion as the rider pedals, mimicking the clopping of a horse.

All the pieces are cut out by a CNC on a single sheet of wood, and the buyer assembles it. The group has started a target pre-order run of 1000 units before they ship in March of 2013. Coconuts are not included, but no matter. I can’t wait to see this gadget put on an asymmetrical mount and strapped to John Guy’s Rocking Horse Bike.
