Empowering Cyclists Since Implementation

We don't just fix bikes. We teach you the secrets of the derailleur and the grease, turning every rider into a self-sufficient wrench-master.

Why depend on a shop when you can master the machine yourself? At Gemstone Gears, our mission is to make advanced bicycle mechanics accessible to everyone in New York, from daily commuters to weekend warriors.

Hands-on bicycle maintenance instruction

Legends of 50th Street

Our journey began in a small basement on 50th Street, fueled by a single repair stand and a massive pot of coffee. We realized that NYC’s riders were brilliant but often intimidated by their own derailleurs.

For 12 years, we've remained committed to sustainable transport, ensuring that every bike leaving our shop is not just repaired, but understood by its owner. We're proud to be a cornerstone of the New York cycling community.

Sustainability First

It's simple: a well-maintained bike lasts a lifetime. By teaching you to build wheels and upgrade components, we reduce mechanical waste and promote a healthier city.

How do we measure success? By the number of riders who can confidently fix a broken chain in the middle of a rainy Tuesday commute without calling for an Uber.

What our students say

"I used to be terrified of touching my disc brakes. After just one workshop at Gemstone Gears, I feel like I could strip the whole bike down and rebuild it myself. The confidence they give you is worth ten times the course fee."
