Aaron Gordon, who is a data reporter at Bloomberg News, has been working on his coding skills. And so for absolutely no reason whatsoever, he decided to map out the life of one of New York's Citi Bikes, specifically Citi Bike #32606. The dataset is pre-pandemic because Citi Bike stopped publishing unique bike identifiers for each trip around 2020. But based on historical data and far as we know, #32606 is the most-used traditional bike (i.e. not an e-bike) in the history of the Citi Bike network.
It began its life on October 15, 2017 at 11:08am in Park Slope, Brooklyn, and then went on to accomplish 7,060 miles (~11,361 kilometers) and 8,624 trips over a period of 806 days. This works out to an average of just over 10 trips per day. In total, this bike traveled the equivalent of a return trip from New York to Los Angeles, and then a short trip up to Burlington, Vermont. And it was all done with only leg power.
Here's the visual mapping that Aaron created:
What I love about this passion project is that it starts to show just how impactful something as simple as a single shared bicycle can be for a city. These bike networks are relatively new, but they're already doing a lot of heavy lifting when it comes to urban mobility. Earlier this week, we learned that in the City of London, cyclists now make up 2x the number of people in cars. And that of the people cycling, 17% of them do so using a shared bicycle.
In the case of New York, the Citi Bike network had ~128,000 active members and ~34,000 bikes as of February 2025. What you're seeing above is the story of just one them.

The City of London, also known as the "Square Mile," is the financial district of London. Some 678,000 people work in the area, nearly 9,000 people live in it, and millions visit it each year. So it's an intensely used square mile (~1.12 square miles or ~2.9 square kilometers). Given this intensity, do you think that it would be reasonable, or even possible, for all 678,000 people to drive their own car to work and not experience crippling traffic congestion?
Obviously not, and the data reflects that:
Motor vehicle usage within the City of London is nearly a third of what it was in 1999. This is a result of moves like the city's Congestion Charge (introduced in 2003) and new Cycling Superhighways (introduced between 2015-16).
Cycling increased 57% from 2022 to 2024. Personal bike usage increased 36%. Shared dockless bike usage increased 4x and now makes up 17% of all people cycling. During daytime hours (7am to 7pm) cycling represents about 39% of all on-street traffic, which is nearly 2x the amount of cars and private hires. And based on current trends, cycling is forecasted to become the dominant all-around mode of transport within as soon as two years.
People walking, wheeling, and cycling now make up three quarters of all travel, up from two-thirds in 2022. This is a huge percentage.

This year, 88 companies delisted or transferred their primary listing away from the London Stock Exchange. Only 18 new companies listed. This, according to FT, marks the biggest net outflow of companies since the financial crisis.
A lot of these companies are, of course, moving their listings over to the US. The New York Stock Exchange and the Nasdaq are, by far, the two largest stock exchanges in the world by market cap. And so many companies believe that they'll generally have a better time being listed over there -- better access to capital, greater liquidity, etc.
This is not a new trend. Last year, the FT also called out the London Stock Exchange as being the European stock exchange with the greatest risk of seeing companies depart for the US. Here's what's been happening since the financial crisis:
Some people may not think that this is a big deal, but it certainly undermines London's position as a pre-eminent global center. Most rankings of the world's best or most global cities have London and New York out front. But from an economic prosperity standpoint, the US hegemony is real and feels even stronger right now.
Naturally, this decline will also trickle through other parts of the economy. On the real estate side, prime central London is seeing the biggest buyer's market since the financial crisis. (Presumably this is true of other submarkets as well.) On the new construction side, sales and starts are falling, and unsold homes sitting as developer inventory are increasing:
It is tempting to say that London will always be London. But:
“The UK market does not have any god-given right to be a leading listing venue, [but] it requires nurturing and support to be successful in a market that is increasingly global,” said Hall, adding that “more companies will depart” unless action is taken.
This is true of every city and every industry. There are no guarantees. Cities need to compete, just as companies compete. I am also of the opinion that Brexit has and will continue to be a drag on the UK economy. Disclaimer: I'm not an economist. But the UK is a relatively small country. So intuitively, I would think that the way to compete with the scale and dominance of the US is through a more unified Europe.
