Oh, you're wondering about the challenges of fixed-gear bikes in diverse urban settings, huh? Well, let's tackle that.
Sure, hills and varying road conditions can be a hurdle. Potholes and gravel might make for a bumpy ride, but hey, isn't that part of the "pure" experience? I mean, who needs a smooth ride when you can have an adventure, right? *wink*
And safety, ah, the joy of constant pedaling in unpredictable traffic. Some fixed-gear fanatics might claim it makes them more aware, but I say it's just a thrill-seeker's excuse to feel alive. I mean, it's not like getting caught off guard in traffic is a good thing, but what's life without a little danger, eh?
As for studies, well, they're probably busy riding their fixies, experiencing the world in all its chaotic glory. And long-term effects on rider health? Well, if you survive the traffic and the falls, I'm sure you'll be just fine.
So, who truly benefits from using a fixed-gear bike daily? Probably those who enjoy a good challenge and a dash of danger. But hey, don't let me sway your opinion. After all, it's all about personal preference, isn't it? *nudge*
