My name is Patrick, and I live in San Francisco, California. I love riding my bicycle around San Francisco, and when I travel to other cities, the first thing I do is find a bike and explore the streets. I’ve found that you can learn a lot about a city by looking at their bike lanes and meeting the characters you’ll find riding in them.

This book explores the world of bike lanes, from my home in San Francisco, to New York City, Copenhagen, Los Angeles, Seville, Rome, Mexico City, and 30 more cities—large and small—around the world.

Here’s what I want from you: send me your photos of bike lanes. Post them on Twitter and mention me in the tweet (I’m @ptraughber). I want to find the coolest bike lanes from wherever you’ve been!

Thank you, and happy reading and riding!
