The Workshop
Inside her tight Brooklyn workshop, Sandra Alfonzo cuts steel and re-engineers momentum. Every custom adaptive bike is a testament to grassroots resilience and meticulous craft, designed for children to experience mobility freedom.
Our Core Belief
Four wheels keep a child watching from the sidewalk; three wheels put them in the street with their friends.
This isn't about charity. It's about engineering freedom, fostering community, and ensuring every child has the right to ride.
