Drawing on a heritage from Ibis, Fat City Cycles, and the American SteepleJack, the Brooklyn Machine Works Park Bike brings the small rear wheel concept into the next century. The frame is 100% 4130 chrome-moly and shares the same general construction techniques used in our BMX frames. It's really a big BMX bike more than a mountain bike.
