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:
- 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 StatesConfinement Relief
Choosing, ordering, delivery and installation of my Harper single geared bike gave me needed relief while being confined. No availability to gym I returned to my 1950/1960’s excercise routine in my apartment. What was missing: my daily bike ride through my community. It has returned with an enjoyable comfortable 1 hour daily ride. Love my bike!! Thank you

United StatesGreat Bike, Great Value
It was really easy, from finding the right size, it was delivered nicely and packaged well. It was very simple to put together I pretty kinda handy but not a pro. I did mess and I put the front fork on backwards which made me think the bike was messed up! I messaged Retro on IG and they answered the next morning explaining to flip the fork. The bike rides really well though, I would recommend taking it to a bike hope to make sure you did everything correctly afterwards. The bike comes half put together. I have had the bike for about 2 weeks and its been really great for the quarantine. Ill take it to get tuned up afterwards. The bike is pretty light, I can lift it with no problem with one hand. I am 5'7 or 8 and got a medium bike . Thank you!

United StatesThanks Retro Team
I had originally ordered the Harper because the Beaumont was out of my size “S”. I got an email the next day that my payment was refunded because the Harper was not in stock, but they also included the Amazon link I can order from right away. They even replied and answered my question regarding sizing for the bikes. In the end, I purchased the Beaumont in size “M” (which worked out perfectly) but the support and team at Retrospec was awesome. They were really helpful and the entire process was just so easy. Thanks guys!

United StatesFirst bike!
Great experience! I was recommended this bike from a friend who has the same one. He said it was a good and cheap bike. I ordered it online and it showed up a week later. Everything in the box along with tools to assemble. Loving this bike. No issues.
