James, a friend from San Francisco, forwarded me this photo as a reaction to the previous post. Wow what a minimalist approach. Retro and futuristic at the same time. The seat looks like those of early walking machines, and the pedals attached to the hub is reminiscent of a boneshaker. The pedals for boneshakers where on the front hub and not the rear. I wonder how it rides? For more, here is a timeline of the history of bike design.
