Products can only be shipped to U.S. addresses.


Retrospec’s take on single-speed/fixed riding is your new go-to for commuting, coasting, and cruising far beyond point A to point B. With a quick flip of the back wheel, Harper turns from a single-speed cruise to a fixed-gear ride. Harper’s hand-built high-tensile strength steel diamond frame is designed for longevity. Ride comfortably with riser handlebars for improved posture. Powerful front and rear hand brakes come standard on our Harper and provide exceptionally controlled stops. Machined braking surfaces engineered onto the rims make for safer, faster, and more efficient stopping.

Flip-Flop Hub
Harper is your two-for-one sidekick. With a quick flip of the back wheel, Harper turns from a single-speed cruise to a fixed-gear ride. Riding fixed has its advantages (including a guaranteed workout) but it’s not necessary to ride that way if you don’t enjoy it. Switch it up again with a quick flip of the rear wheel. Fixed-gear bikes famously have fewer moving parts so you can keep moving.

Retrospecs not interested in anything but the best. Harper sports top-of-the-line components for smooth sailing and effortless riding. VP freestyle pedals, KMC ⅛” chain, 25.4mm riser handlebars, front and rear Promax brakes, help you maintain total control of your ride. 30mm Deep V rims and thick, stable tires ensure a smooth ride, gripping to city streets regardless of conditions.
