Buenos Aires bike advocate Matias Kalwill took a break from his vida en bici to illustrate this article

After biking in Buenos Aires, it seems clear that people in other cities are forming indigenous, exciting bike cultures. But this turn to bicycles is less of a globalized fad as much as water naturally finding its level. In a world where the future of fossil fuels is uncertain and people everywhere are beginning to see the need for a more sustainable lifestyle, urban biking is a matter of common sense.

For Kalwill, the rise of the bike means a better future for his home. "It brings hope that things can change. And we need big changes if we expect to survive in a world that's getting more crowded and warmer. We need hope. In Buenos Aires, bikes seem to be providing that."
