Imagine a city with no cars, free bikes — and 50,000 people in one square mile

The brains behind a conceptual, planned community in Colorado is imagining a city where cars aren’t allowed, bikes are free and 50,000 people live within a square mile.

Blogger Pete Adeney and Amsterdam-based property development agency, B4place, say that if their conceptual “Cyclocroft” community between Longmont and Boulder were to be built, they would start from scratch to avoid “antique car-based building/zoning rules,” according to Forbes.

Adeney, who has 300,000 regular readers blogging as “Mr. Money Mustache,” concedes people will deride the idea as a “high-tech hippie commune,” but told Forbes a settlement like Cyclocroft could attract Millennials and other people who don’t see living closely together as a compromise, “but rather an opportunity to regain once-cherished benefits, including incidental socialization and collaboration.”
