The Pi Bike is a fixed gear bicycle handmade out of carbon fiber in the shape of pi (π) symbol. Martijn Koomen and Tadas Maksimovas created the design and made a fully functional bicycle.
We collaborated with WE ARE Pi and launched The Pi Bike a few days before Pi Day which is celebrated on March 14th, the closest date to the mathematical number “pi”. Coincidentally, March 14th is also Albert Einstein’s b-day. So, what could be better to celebrate the Pi Day than having Albert Einstein to ride The Pi Bike?
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
