Pi Day may have just passed, but if you own the Pi Bike you can celebrate everyone’s mindfuck of a number every day. Designed and created by Martijn Koomen and Tadas Maksimovas, the Pi Bike will provide for countless enjoyable rides that offer time to think about how we’ve discovered 22 trillion digits and are still no closer to the end of pi. The fixed gear bike was made by hand after many cardboard and plywood test models were put through the wringer. After they settled on a balanced design that functioned properly, the final version was made from carbon fiber. If you’re a mathematics professor who bikes to school, we’re pretty sure you find a better two-wheeler.
