Riding an ebike in 39c is uncomfortable but not unthinkable. I do it semi regularly. If your trip is >10km it's not that bad at all. You will probably have to shower when you get home but it's still better than owning a car.
I've ridden mine in up to 35C and it's like stepping into an oasis compared to standing still in that temperature, more so if you wear clothing like loose fitting cotton clothing that benefits from the increased airflow.
39C is well above skin temperature so you're only going to get evaporative cooling and the effectiveness of that depends on humidity. It's possible the heating effect of the hot air blowing over your skin overwhelms the evaporative cooling and you are actually getting net warming.
Even if the humidity is low if you're not already drenched in sweet, it's going to feel awful.
Exactly. Before 1950s 90% of the people walked, rode bikes, horses, etc in all of these places, everyday, everywhere.
Billions still do all over the world in similar climates.
It's not like we need cushions, air conditioning, and so on, to go from one place to another in the summer heat.
Yes. And it sucks. There is a reason the founder of Singapore said it “made development possible in the tropics.” We don’t “need” indoor toilets either. But they’re pretty great. So are cars. Big SUVs with the AC turned down to 65.
Yes, it is stunning.
Especially when its being confused to something like a basic human right -- that everybody should just adopt, instead of the spoiled result of a consumerist society, enabled by first world wages and cheap energy (subsidised by exercising global power).
As is the idea that the lifestyle of your country (or your adopted country) is the best in the world, and everyone should follow suit, with big SUVs and AC to 65" -- and if they don't do it, it's only because they can't afford it (never mind that places that can very well afford SUVs and full-on AC blast, like in most of Western Europe, happen to shun both as tacky).
Even more so a livable planet, and we're running out of that just so some cushioned entitled people can have "big SUVs with the AC turned down to 65", 24/7 burgers, and other BS...
