Harper is sleek, stylish, smooth, and low-maintenance. A hand-built steel frame and flip-flop hub allow you to ride fixed-gear or free, making Harper the perfect whip to work, class, or brunch.

Our 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.

COMPONENTRY

We're 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.

      Perfect Minimal Bike

      This is an amazing bike for the price! I'm in Baltimore for grad school and when my old bike was stolen out of my basement I needed something quick, at a lower price point than my old one, and something less flashy—to not attract any unwanted attention. I call this bike my sleeper bike in that it rides like a champ and never gives me any issues. It blends in but also stands out. If someone were to lift it again, it wouldn't be the end of the world because it was such a reasonable price. The best part is how quiet and smooth it is to ride. I also find that the slightly wider tires help if you hit an unavoidable pothole or something like that. I would highly recommend this bike if you are like me and need something a little more pedestrian yet quality. Good job Retrospec, you made my life a bit easier!
