Bicycle User Experience (BUX) envisions cities where cycling is an inclusive, accessible everyday form of transportation that fits seamlessly into people’s lives and benefits all.


We believe that to plan and design streets for widespread, inclusive everyday biking- for people of all ages, abilities and backgrounds- the conversation needs to shift towards studying everyday people and making bikeways that work for them.

What we do

BUX provides learning opportunities on cycling experience and people-centered design, maintains an open toolkit of methods for human-centered bikeways, and offers professional services to equip planning organizations with the tools to understand and design for everyday people's experiences while cycling. We help you to rethink bike planning: study people and fit the bicycle into their lives.

BUX Network

The BUX Network is a group of professionals of diverse backgrounds looking to make biking a better experience in their home cities. Every 6 weeks, they have design sprints to ideate solutions for one specific case city, and write about this on the BUX Blog. BUX hosts this group with collaborators. Current members are represented in the adjacent map.

  1. Why you think cycling experience and the human perspective are important.

  2. How your work connects to this.

  3. A bit about yourself.


The idea for BUX arose in 2016, when founder Trey was inspired by a usability class at The New School. Why shouldn't bikeways be designed with people in mind just as much as the user experience profession does for an app or website? At the end of 2019, BUX was registered as a company in Amsterdam, with Dutch KvK/Chamber of Commerce number 76825957.
