Turning data into tangible experiences
New York artist Justin Blinder has ingeniously merged technology and social commentary by designing a device that automatically slows shared Citi Bikes when they traverse high rent-burdened areas of New York City. The innovative project, titled Ground Truth, leverages Blinder’s background in data and design, drawing on his past experiences as a bike messenger.

The device features a 3D-printed casing and clamps onto the front fork of the bike, interacting directly with the brakes. It uses data from the American Community Survey to assess rent burden, defined as the percentage of income spent on rent and utilities, modifying the bike’s speed based on this metric.
A new lens on urban living with artist Justin Blinder
“The city stopped feeling like a map and started to feel like a sequence of rarely relatable conditions,” Blinder shared, emphasizing the need to physically navigate through affordability, instead of just mapping it. The project offers a visceral interaction with housing data, which is traditionally abstract and inaccessible.

Blinder’s endeavor is a response to the visual complexity of affordability. By using datasets from the American Community Survey, he combines statistics on median income spent on rent and those paying over half of their income on housing to inform the device, as outlined on his website dedicated to the project.
Braking for awareness
As cyclists move through more expensive neighborhoods, the device increases brake tension, while in more affordable areas, it decreases resistance. It’s designed for easy installation, featuring a compact computer, GPS, and a servo motor to adjust the brakes. A small screen informs riders of the local rent burden percentile and offers a QR code for more information.

The device isn’t just about the physical biking experience; it’s symbolic of the city’s socio-economic divides. Although the device isn’t permanently attached to any public bikes, Blinder has facilitated group tours to demonstrate its impact, with support from Idle Hands, a Brooklyn-based incubator.

Opening the conversation and technology
Blinder aims to transform Ground Truth into an open-source project, allowing others to replicate and adapt the device for broader use. “Urban infrastructure isn’t just functional. It’s a symbol of social signals about who places are for,” he explains, highlighting the dual implications of accessibility and displacement.

The project resonates with global efforts to address housing crises, such as those seen in Sweden’s tiny housing initiatives by Riksbyggen and ADU policies in New York under New York mayor. Blinder’s project invites thoughtful engagement with urban spaces, urging us to understand and engage with the city’s evolving landscape.
