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.

Building community, advocating for people-informed improvements, and sharing in the joy of biking are what drove Audrey to SF Bicycle Coalition. She has faced the woes of the lack of bike infrastructure, dangers of uninformed drivers, and lack of safety that is rooted in being an exposed women of color on a bike. Now with a family, all these decisions complicate her relationship to her bike even more so. Audrey’s background is in transportation planning, racial and social equity planning, and people-powered decision-making from her leadership role in my union.

Throughout his work on those projects, he realized the importance of SF Bike Coalition’s members and was inspired by their tireless efforts towards advocating for project approvals.
