Bicycle User Experience (BUX) helps you to rethink bike planning: study people and fit the bicycle into their lives. We are based in the Netherlands and internationally-oriented with a global network of collaborators, learners, and clients.

What we do

BUX provides courses and trainings to help urban mobility professionals make usable cycling infrastructure and consulting to organizations looking to transform their approach to street design. We maintain the User-Centered Cycling Methods toolkit, and support a global network of professionals and activists working on making people-centered design for cycling a reality.
