PRODUCT DESCRIPTION

Critical Cycles fixed-gear bicycles are hand-built for the commuter lifestyle with a tig-welded steel frame that comes with horizontal dropouts and a component set that is ideal for riding around town, on the beach boardwalk, or for performing freestyle tricks.


Each bike includes a flip-flop hub so you can easily switch cogs from and cruise on your freewheel like a standard single-speed. Our Wanda tires are optimized for city riding making even potholes and rough asphalt a breeze. Every bike comes with a sealed bottom bracket so moisture or dirt will never cause problems.
