> I can tell you're just like "well, the poors can just ride bikes" having never ridden one yourself
I did ride one to and from work for 3 years, specifically because I couldn't afford a car at the time (and then later did buy a car but couldn't afford to drive it for my daily commute because I was unemployed).
> otherwise you would know that a bike that you could cycle a 40km to 60km round commute on in a rural area
Maybe if you hadn't "disregarded the rest of the post" you would've read the part about using bus services to cover most of that distance. Bus fares are an additional expense, sure, but you can readily save money on a monthly pass, and plenty of transit systems offer discounted rates for low-income riders (though I think $10/hour might be above the typical threshold).
Not that such a commute is typical even in rural areas anyway. "Rural" areas include small towns/cities, and quite a few of the jobs in such towns/cities are within those towns/cities. Ain't everything way out on some random farm (though even in those cases, you'll typically have access to live either on or very close to work; this is a common living arrangement for migrant workers in California).
The furthest I had to bike for work was a one-time computer repair job about 13 miles outside of town, uphill in the mountains. Did that on my bike, even while carrying parts and tools.
> when you don't need to pay for food
Like I said in the comment: even if I didn't have that particular resource (for which I'm grateful and count myself lucky), I still had enough from my paychecks to cover that. That money went into savings and the occasional meal eating out instead.
And I still did need to pay for most of my food; the main things they brought were soup and Spam (because they could buy them on the cheap at Costco), plus a bag of rice if I remember right. I was on the hook for anything else.
And mind you this was with no roommates and more than $1k/month rent; there were plenty of other areas where I could've trimmed my budget and made things work.
> not to mention the fact that the cycling clothes you would need to buy
You don't need cycling clothes to ride a bike.
> Not to mention your mechanical service, which if you're commuting daily is probably $80 every six months, $15 for brake pads, $5 every time you puncture any wheel, $60 for new tyres every year,
All of this is still a tiny fraction of the $250/month figure for a car.
Though I will say that in the 3 years I did ride my bike daily I didn't change the tires once. Nor did I change the brake pads. Probably should've taken better care of that thing, lol
