The 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.

Retrospec's 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.
