It's a one-speed. Fast.

If you had asked me as a child how to break the world speed record on a bicycle, I would have told you to strap rockets onto it, and then I would have looked at you funny for asking me such an easy question. As it turns out, hypothetical-arrogant-child me was right to be so cocky, because that's exactly what Swiss cyclist and speed demon François Gissy did to smash the world record (his own) for fastest speed on a bicycle by reaching a Schwinn-melting 207 MPH in under 5 seconds at the Circuit Paul Ricard race track.
