Bicycles built for long duration use - people do ride for 16-24 hours straight more than you'd think do exist.
Sure, but those bicycles don’t cost 100 bucks they probably cost 5000+. The last bicycle I bought was $7000 and that was midmarket (my recreational cyclist standards).
I don't think many people do that, and if so, how many of them do it on one that cost "couple of hundreds"?
How many of them do that every day?
And of those people that do, how much do you think they spend on their bikes?
