Fixed Gear or Freewheel?

We chose a flip-flop rear hub to give you the flexibility to ride fixed or freewheel. Riding fixed gives you an unmatched feeling of connectedness to the bike, the road, and helps you perfect your pedal-stroke. Riding freewheel gives you the ability to coast and cruise, just like the single-speed you grew up on! No matter which you choose to ride, the standard front brake guarantees you can stop either way.
