Retrospec Harper Coaster 53 Single Speed Bike. Harper is designed for city riding. Grooved tires grip the pavement and dispel water. A coaster brake helps you to stop on a dime at unexpected red lights. Barspin clearance with no toe overlap allows you to make sharp turns. Harper is as simple as it gets. Single-speed bikes boast fewer components than multi-gear bikes, which keeps them lighter, less complicated, and easier to maintain. Enjoy an easy ride without all the bells and whistles.
