In case there are any other fixed gear riders that may want to have a look at my hoverboard, here are some pics of my commuter singlespeed. This bike is an IRO Mark V (56cm) that I ride to work every day. After several mods to it, I am very happy with the weight and feel of the bike. Just a few basic upgrades like a comfy saddle, bullhorns/time trial bars, and I use front and rear brakes so I don't kill myself or anyone else. I hate the tires I have on it right now, but it is a fun bike.
Thanks for the great site! Kelly D. Williams
