"The Curbside features a lightweight aluminum frame and flat bar with 700C wheels for quick acceleration and great maneuverability. The rear wheel uses a flip-flop hub with a freewheel for easy around-town riding, but can easily flipped and used as a fixie with the addition of a track cog. Making the bike even more practical are fender and rack mounts for those who need to transport gear or stay dry in the rain."
