Our Thesis


Thesis is an act of rebellion. We believe that creating a great bicycle starts with you, so we help you create and customize a unique bike for your body and terrain. We recognize local mechanics and fitters as the unsung heroes of the cycling world, so we co-build programs to empower them to grow their businesses. And we believe that bikes don’t have to be so expensive, so we work directly with the best factories to bring you high-performance bikes at a revolutionary price.

We’ve set out to build the best bikes in the industry. Here’s how.


Premium bikes at a revolutionary price.

We build every bike to order, so we don’t have expensive warehouses with lots of unsold bikes. We have a small remote team, so we skip the long commutes and cubicles. And we partner directly with the factories behind the industry's leading brands to bring you amazing technology at a revolutionary price.

A bike built uniquely for you.

You're not generic, and your bike shouldn't be either.

Want to customize your bike?  Let's get it dialed for your favorite terrain and have it fit your body like a glove. You can tune your wheelset, drivetrain, and gearing, and even change the size of your handlebar, stem, crank, or dropper.

Invest in what matters.

We design to a mechanic’s high standards and go obsessively deep on curation. There’s a story behind how we chose each component, right down to the bolts and bearings, and we take you behind the scenes on every single one.

Hand-built by a seasoned mechanic.

Each Thesis bike is hand-built by a single professional mechanic -- not a factory assembly line. You'll have one seasoned pro building your bicycle from the frame up, then going over every last bolt to make sure it performs to its full potential for years to come.


We're in this together.


We think of our riders as good friends. We create our bikes with an intimate approach of integrity, transparency, and love -- you won't find corner cutting or marketing hype with us.

We embrace feedback and we’re committed to being here for you at every moment of your ride.


We seek to build partnerships where everyone can win. We empower mechanics and fitters, the unsung heroes of our industry. We treat our factory partners like family. We want everyone to grow with us.

Radical inclusion

We welcome cyclists of all stripes and riding ability. We are united by our love for bicycles, the journeys they take us on, and the joy that comes from powering through the struggle.
