Kommen wir nun zu etwas ganz anderem. Was Mathematik mit Fahrradtechnik zu tun hat.

This video explores some of the challenges in designing early bicycles and how concepts such as wheel circumferences, gear ratios, and torque were used to solve problems.

I feel that the engineering of bicycles is a great way to connect some basic mathematical ideas into mechanical problem solving. Playing with properties of circles and ratios as a way to make a bike move faster builds a context to bring these geometric ideas into something physical and creative.

The story also shows how creativity and engineering don’t follow a linear path. Seeing novel solutions, failed experiments, and missed opportunities give us a great framework to inspire us and guide us through new problems.

Mit dem Buffalo Bicycle S2 hat man ein Fahrrad mit zwei Ketten auf zwei Singlespeed-Antrieben entwickelt. Ich habe mich erst gefragt, wozu genau das gut sei soll. Aber irgendwie ergibt dieser so gut wie wartungsfreie 2-Gang-Antrieb durchaus Sinn. Keine Ketten-, keine Nabenschaltung und dennoch eine Übersetzungsbreite falls es mal schwerer wird oder einen Hügel bergauf geht.

The Buffalo Bicycle S2 is a robust, utilitarian, and serviceable bicycle made to help the most remote communities on the planet. What makes it unique is that it has two chainrings, chains, and two freewheels. Today, we will closely examine the S2 and show how its revolutionary engineering makes it even more reliable and useful than the original Buffalo Bicycle with its one-of-a-kind drivetrain.
