I have an 18" Redline Monocog Single Speed in great shape.I just serviced all the bearings more for fun than neccesity.  Has flip flop rear hub for additional cog or fixed gear.  It is black with red lettering, all steel with a rigid steel fork, v brakes, sweet new Maxim stem and machined AVID brake levers are upgrades.  Email for pics.  This would be  sweet ride for spring.  Comes with flat pedals. 

Asking $300 OBO
