Brooklyn-based artist Justin Blinder developed Ground Truth, a bike-mounted device that makes pedaling harder in areas with higher housing costs.

The small gray box attaches to the front fork of a bicycle and adjusts its resistance based on local affordability. In cheaper neighborhoods, biking becomes easier; in more expensive ones, it gets tougher. This tangible representation of economic disparities offers a unique insight into urban living.

Blinder’s inspiration came from his observations during food delivery rides. Noting the stark differences between neighborhoods, he sought to transform abstract economic concepts into a direct physical experience. His project uses data from the U.S. government's American Community Survey to assign brake tension values according to housing affordability in each area.

The device is simple yet effective. It relies on an ESP32-S3 microcontroller and a servo motor, all controlled without breaching the bike’s closed system electronics. Blinder’s goal is not just to raise awareness but also to engage social elements, such as allowing riders to contribute to the project.

By challenging preconceptions about affordability, Ground Truth encourages users to rethink their perceptions of urban life and economic inequality.
