A Brooklyn-based artist has developed a bike accessory called Ground Truth, which makes pedaling harder in areas with higher housing costs to highlight economic disparities.
Justin Blinder made a bike accessory that makes it harder to pedal in areas with expensive housing. It uses data from the government to show how much money people spend on their homes and apartments.
Analysis
{"#housing-data-challenge":"Finding accurate housing data was a significant challenge for Justin Blinder. He used the US government's American Community Survey’s Rent Burden dataset to measure the proportion of income spent on rent and utilities in different neighborhoods. This data allowed him to assign each census block group a value corresponding to the amount of brake tension the device should apply.","#ground-truth-project":"Ground Truth is an external mechanism that attaches to the front fork of a bike, increasing or decreasing resistance based on housing affordability. The hardware includes an ESP32-S3 microcontroller, a GPS module, and a high-torque servo motor. The enclosure fits perfectly onto the frame without additional hardware.","#legal-and-social-considerations":"Initially, Blinder considered using Citi Bikes for group rides but was concerned about potential legal issues. He is also exploring ways to make Ground Truth more socially interactive as an art project."}
Key points
- Justin Blinder created Ground Truth to highlight economic disparities through bike resistance based on housing affordability data
- Ground Truth uses the US government's American Community Survey’s Rent Burden dataset for accurate measurements
- The project could evolve into more socially interactive forms as an art installation
Ground Truth could help raise awareness about housing affordability issues, leading to more equitable urban planning and policies.
The project might face legal challenges or resistance if used it is seen as a form of protest against luxury developments in affordable areas.
