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.

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:
- Stand upright with your feet 6-8" apart.
- Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
- 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.

United StatesNice 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.

United StatesGreat fixie for that price tag
Received mine super fast, easy to put together. It’s a great bike for the price, not the highest friction less components, but they do the trick, and the bike looks pretty badass

United StatesWow. What a deal. Exceeded expectations.
In less than thirty minutes I had the Harper single speed out of the box and ready to ride. Fantastic deal for the price. I am happy with the quality and value. The bike is a blast to ride, has me standing up out of the saddle going up slight hills, but the simplicity of a single-speed brings a different joy to riding. As an avid MTB'r and Roadie, the pleasure of taking this bike back and forth to work every day, or the occasional trip to my favorite brewpub, is unsurpassed. Nice comments every place I take it as well on its overall appearance. I am thinking about buying one for my lady friend now.
