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.

      Beautiful BUT was the wrong size

      I loved the bike but when I tried standing over it, I realized I bought the wrong size and had to send it back. Unfortunately they do not have an exchange policy everyone, so Mabel sure you get the correct size or you will be paying for shipping back to california. Overall I wish the size fit me because that bike was everything I could’ve asked for :( just waiting on my refund to repurchase the correct size!

      Love it!

      The bike is great and exactly what I needed and wanted! Makes getting around a city way easier! It’s light too, so makes it easier to get up and down steps with it! Would highly recommend!

      Harper Fixed/Single Speed

      Bought this strictly as a commuter bike. Was happy the assembly was very easy but not pleased that my rear tire rim was out of alignment and rubbed against the brake pad. Luckily, I’ve worked at a bike shop and know how to remedy but for someone else, it would have been a $15-20 trip to the local bike shop to correct. Satisfied with the rest of the bike & performance.

      Nice little bike

      I got this about a week ago for my daily commute of about a mile or two each way and so far it's fine. Pros; fast, the fixed gear is fun, it was easy to assemble at home. Cons; cheap components, thin metal and weak plastics. All in all though, it's remarkably simple and safe, makes my morning ride fun and easy.
