The Pi Bike

The Pi Bike is a fully functional bicycle designed by Martijn Koomen and Tadas Maksimovas, handmade from carbon fiber material in the shape of the mathematical symbol, Pi (π).

The Pi Bike was officially revealed in March 2017 to coincide with Pi Day, the annual international celebration of Pi, observed on March 14th each year. As luck would have it, March 14th is also Albert Einstein's birthday. So, what better way to celebrate the grand reveal than an inaugural ride for the genius himself?

The Making of

Martijn Koomen and Tadas Maksimovas began this project after first seeing the work of Malaysian illustrator Tang Yau Hoong. Martijn and Tadas embraced the complex challenge of taking a simple drawing and rendering it into a fully functioning 3D object.

During the development process, prototypes were produced from simple materials, such as cardboard and plywood. Once the design of the frame was finalized, a resin prototype was cast for testing.

We cast the frame from carbon fiber material for the finished product, which offers precisely the characteristics needed for a strong, sleek, lightweight bike frame. We fitted wheels, a high-end crankset, and racing handlebars, and the finished bike was ready for its reveal.

Selected Publications

The Pi Bike received critical acclaim and was featured on numerous design, tech, and lifestyle blogs, including Designboom, Design Milk, Curbed, Creapills, Yanko Design, New Atlas, Cool Material, Tabi Labo, and GQ Turkey.
