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.

Measuring Inseam

Inseam is the most important metric to consider when deciding on bike size. In order to take this measurement properly, follow these guidelines:

  1. Stand upright with your feet 6-8" apart.
  2. Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
  3. Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.

Bike set up took minor elbow grease thanks to it coming partially built. I’ve had short and lengthy trips mixed of city and smooth bike trails and each time has been great, I am 5’2 and have been able to ride very comfortably and confidently by choosing the XS model. Thank you Retrospec! :)

TERRIBLE BIKE, EVEN WORSE CUSTOMER SERVICE

Bike is not great, kind of flimsy and has very cheap parts. After expressing concerns with customer service regarding Retrospec shipping issues and a missing manual, the agent proceeded to blame me rather than taking responsibility. Very disappointing customer experience.

Money well spent

The tires are not great at holding air and my seat becomes loose every time I ride it but honestly you're still getting your moneys worth and then some. Its nice to ride and it is just all around stress free unlike if I was using a few hundred/thousand dollar road bike.

Disappointed

Directions to put the bike together were not well written, have had problems with the seat and the bike tires constantly deflate

Good price for this bike

The bike is a bit heavy but it’s not a big deal. It is the fastest bike I have ever seen until this time !! I recommend highly
