600miles on the bike.... very little maintenance, mainly cleaning the bike and lubing the chain. Gear ratio perfect for commutes and still be fast enough for 20 plus mph bike club rides. I easy to skid stop and haven't replaced my tires yet. The still frame is light enough but strong to take the abuse of the bumpy roads. Its not the fastest fixed gear bike but it can keep up if with the roads if your legs are up for it. I mainly use it for my everyday commuting, with occasional bike club rides.
