Made in Brooklyn

We design, prototype and produce all of our bicycles in our Brooklyn, New York fabrication shop. Your frame is mitered, welded and aligned under high scrutiny and is guaranteed to be a unique, finely crafted ride. 


Race Tested

The Hammer Track is a race tested machine. Whether you are riding in the velodrome, alleycats or criteriums, this bike is built for going fast and tearing it up! All of our frame designs are race tested and have podiums around the world.


Built To Shred

All Hammer models feature an asymmetrical rear triangle with the extra stiff Speed Stay -TM drive side, ensuring direct power transfer from the pedals to the pavement.
