The Jamis Beatnik 2011 Single Speed Road Bike. Singleness doesn't refer to the number of speeds, but to the feeling of connection when you're spun out, on top of the gear, and just flowing through the streets. Jamis know that. They get it. And that's why their Beatnik fixies are so highly coveted, and such a closely guarded secret amongst inner city masters of spin. They stick with welded steel frames, because these bikes are built for the harsh reality of the streets, where there's no room for lightweight alloys and carbon-those are fine materials for racing bikes and boutique fixies, but they can't hold up to the knockabout world of bike racks, potholes and sewer grates. As they say, steel is real. And so are Jamis fixies.
