Nicholas Aulston

I love the connection between problem-solving and the life of a cyclist. From navigating a new exciting route, to balancing pannier weights, to bike mechanics, life on a bicycle has taught me a lot. Off of a bike, I’ve been curious about the urban condition and have collected experiences ranging from working in Honduras to researching contemporary urban planning challenges such as housing, environmental justice, crime and bike infrastructure through a lens of equity and equality. Currently, I’m focused on Bicis Del Pueblo, a project that brings bike safety, mechanic and advocacy skills to individuals and families in the Excelsior.

Preston rides his bike every day from the Outer Richmond and loves the car-free days on JFK. His motivating interest is democratic ownership and governance over our infrastructure. He currently works at a local internet service provider and collaborates with the City to serve thousands of SF public housing residents with the best internet in the country at no cost. Preston thinks that bike party is the closest thing to an ideal society in San Francisco, and you can find him biking to OB and touching the water on Friday mornings.
