Speaking as both, it is entirely possible to be a “person on a bike” and a “cyclist”.
HOW TO THINK LIKE A PERSON ON A BIKE (AND NOT LIKE A CYCLIST)
“And more to the point: in the rare moments that I find myself in my full-on cyclist get-up, I still care deeply about how the streets I ride through are built. And for the most part, so do all my cross-racing, Chamois-Butt’r-needing, mega-athletic friends who would call themselves cyclists proudly and without a moment’s hesitation.
Cyclists are People on Bikes. And the kind of People on Bikes who will never touch a fiber of Lycra a day in their life still need Cyclists in the fight to create better streets. They also need sympathetic drivers, and transit riders, and people on hoverboards, if those infernal things somehow manage to stick around. We need every single person we can get.”
