Retrospec Harper Single-speed

$299.99

Simple & Reliable City Bike

Harper is designed for city riding. The frame puts you in an engaged, forward-leaning position, similar to a mountain bike but soooo much faster on city streets due to the thinner, slicker tires. Reliable front and rear brakes stop on a dime.

These are made with a flip-flop rear wheel, which means you have the option of riding fixed gear or the default freewheel single-speed.
