Cannondale Jackknife


What do you make of this concept urban bicycle? It is more than just a simple restyling though. It’s a fold-able bike, and it’s axis of folding is pretty unusual – the seat tube itself rotates 180 degrees so that the front wheel flips to the back. What is more unique, however is the absence of any chains (or even chain equivalents like drive shafts). Instead, it is  hydraulic powered – no chain = no grease, no hanging bits as you fold bikes, fewer parts and less maintenance… though I do wonder whether the feeling of riding a bike would be markedly different. I’d have to get on one of these before I know.

After a quick scan of Amazon and the Cannondale website it appears this bike has not yet made it past the prototype stage, unfortunately.
