Regular commuting on rough city streets requires a special kind of bicycle.

Commuter bikes take a lot of abuse, endure rain and grit, scratches and falls, so they need to be bulletproof.

The Retrospec Harper single-speed fixed gear urban commuter bike seems to be the right candidate for the job.

It’s built around a durable steel frame, it has a simple single-speed drivetrain, and a minimal number of parts that could require servicing. On top of that, it looks pretty attractive!

Here’s what we think about it!


Quick Overview

This is a streamlined steel commuter available in two variations: Fixed-gear and Single-speed. Therefore, it’s suitable for different types of riders with varying wishes and expectations.

One of its most authentic features is definitely the appearance.

The Retrospec Harper fixie is a retro-cool bicycle made with a minimalistic approach and available in 11 colors. The Harper single-speed variation comes in two colors only.

The latest model of this bike now rolls on 700C x 28mm tires, which is the ideal size for a mixture of smooth and cracked city asphalt. Plus, they’re wrapped around 30mm Super Deep-V Double Wall Rims that look amazing and give you some aero gains as well.

On the other hand, its main drawback is the plastic pedals, which we recommend swapping for something made from aluminum, just to have added peace of mind.

The differences between the Retrospec Harper Fixie and Single-Speed models are minimal, but still significant. So choosing which one to get could be tricky if you don’t know exactly what you’re looking for.
