do zoomers even know what fixies are?
As for flipping bikes generally, you're lucky if you don't lose money. It's easy to spend 100-200 on consumables to overhaul a bike, and then it has to be higher end to ever see that money back, plus you had to have gotten it for next to free. Most enthusiasts who do custom builds or overhauls end up losing a lot of money if they sell them. That, or, you're doing a shoddy job and a quick clean/tune and just being an asshole who inflates the market.
If you get a reputation as a bike guy though, people will bring you service jobs. You can make money on those if you're actually good at wrenching. Easy to make $20 for an hour fixing someones shifting or brakes or truing a wheel. That's not great money but on the side it will push your hobby of bikes into the green which is good. I'll also charge a flat $100 service rate to fully overhaul a bike/ do a custom build for someone. It's way down on an hourly rate but it's more than i'd get for doing the same thing unprompted.
You can also make money flipping -parts-, but you need to really know what to look for and obsessively pounce on undervalued local listings.
flipping bikes it's helpful to follow two rules
>never explain anything or need to explain anything about the bike, ie, it actually doesn't have any unresolved problems because you resolved them already and
>it should be cool enough that it could be your rider
