Who are we?

Founded in Fall 2021, we are a student engineering club pioneering the bike building field among universities. We design, build, test, and ride bikes, fabricating the frame from scratch and even making our own composites.

We have open enrollment and encourage all majors and people to join our wonderful community! There is every type of work imaginable, from business to fabrication.

We design, build, and test all things bikes with a focus on frames from scratch.

Our Work.

Past projects showcase our commitment to building, testing, and refining real systems. By working on complete bicycle platforms and subsystems, members gain hands-on experience transforming ideas into functional, rideable outcomes.

Our past projects highlight a student-driven approach to engineering, where curiosity and iteration lead the way. From early prototypes to finished builds, we take pride in creating thoughtful, well-engineered solutions that reflect both technical rigor and creativity.

Leads Spotlight

We are a team of undergraduate students at UC Berkeley. Everyone plays an integral role in building a bike, from organizing the business side of things to making custom components. Our community is open to everyone!
