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.

Awesome bike!

Love it! It was simple to put together and is very light. The only improvement I can think of is if it came with a kickstand.

Value

For what I paid, it was a good value. Haven’t ridden a bike in many years so didn’t know what to get. It was easy to put together. It rides ok but makes a noise when I pedal but I will try to adjust my rear tire to tighten the chain as recommended by retrospec staff. Probably will buy more of a cruiser bike with maybe 3 speeds that I can sit more upright while using. Due to my age my neck strains as I ride when looking ahead.
