>>1830386>>1830387>>1830388It's true, we're a dying breed, not a lot of couriers run fixed like back in the day. The builds I commonly see out in the street are ebikes, gravel bikes, and old xc mtbs sometimes with aftermarket/parts bin rigid forks. Most of the people I see riding fixed are old teenagers and young adults who haven't grown out of being vain (fixie fashion for the urban youths), probably their first non-bso bike too so they don't really know fixed is not a noob friendly bike to ride but they can tell it's a lot faster than their boomer cruiser Walmart bso mtb.
There are some advantages to fixed however that I consider really important to making a living out of riding. It's low cost and low maintenance, like my current drivetrain has somewhere around 20k miles, still unchanged (I need to through, kinda too exhausted and poor to properly maintain my bike). An advantage over an ebike is more range, a couple ebikers I know out in the street need to go home and charge to make another run while I could be outside the whole day making runs, the same could be said for unpowered bikes but the extra drivetrain mass of a fixed helps hold momentum, so as long I maintain a certain speed, I waste less energy than those who coast. The final advantage is road feel and control of the bike (I think it's partially also track geometry though), to make a living out of riding, you really need a bike that is nimble enough to slip through tite gapz with minimal time to respond. I almost got doored today (again) and if my bike and I were slow to respond to situations like, I would've been dead a long time ago.
