A Full-Sized Ride — That Folds to Fit Your Life
Break it Down
We started with a standard bike — and took it apart. Our goal was to identify every point of resistance in traditional folding bikes: clunky hinges, awkward geometry, and limited portability.
Rethink the Design.
From frame structure to locking mechanisms, we reengineered everything. We focused on maintaining a full-size ride feel, without the bulk that holds most folding bikes back.
The Result: The Pioneer
The first full-sized, fully foldable bike designed to keep up with real life. Take it on a plane, fit it in your car, store it in your dorm — and ride without limits.

Our Tire
Airless Tires
No more flats. No more patch kits. Just pure ride-time.
We've Reinvented the wheel
With lightweight materials and enhanced traction, they're built for commuters, students, and city explorers who want durability without compromise. This is more than a new tire. It's a new standard in micromobility.
Reengineered Spokes
Structural strength that folds with you.
The Retractability Mission
We’re building the next generation of micromobility — clean, compact, and commuter-ready. As student engineers, we’re starting small but thinking big: designing bikes that reduce reliance on cars, integrate with public transit, and help people ride more while polluting less.
Biking: A Cleaner Way to Move
Every foldable bike we design is meant to reduce dependency on cars. The Pioneer makes it easier to bike more, ride farther, and connect with public transit — cutting back on emissions with every trip.
Engineering for Lower Impact
As students, we’re building with intention. We’re designing smarter bikes that support cleaner living — compact, easy to store, and made to keep people riding instead of driving.
Sourcing with Sustainability in Mind
We don’t use carbon-neutral materials yet — but we’re working toward it. Our goal is to partner with manufacturers who share our vision for sustainability, quality, and ethical sourcing.
Building Toward a Circular Future
In the future, we aim to launch repair and recycling programs to keep bikes out of landfills. We want every Pioneer to have a long, useful life — and a responsible end.
