My mother brought my sister and me to kindergarten and elementary school on one bike early in the morning in every weather. After school she collected us and then went to buy groceries before returning home.

A colleague of mine rides with his son to the kindergarten, each on his own bike.

It works. You just have to work out how to do it. Concentrate on what you can do with a bike instead of what you can't.

I'm Finnish and ride in the freezing rain (literally).

But I can see the advantage in not having to dress up in 8 layers and driving goggles to go sweat to a supermarket for some snack you're hankering.

Also, bigger stuff require a cart and yeah sure you have them on bikes.

But I've been biking for everything for years, used to have a car and I just miss the convenience. Cheapest pure electric cars are getting to be around 5k here so I'm gonna get one of those at some point. I'd love if it would also fit my bike though. It's a 26" but foldable but it's not exactly small folded and with my extensions to the headset.

It's not even "revolve around bike transport", it's just "include bike transport as a serious and viable option".

I imagine that in Denmark people with disabilities have some disadvantages, but I doubt that daily life is virtually impossible because they're unable to bike.

However, in most of the US and Canada, if you don't have a car, your life is extremely difficult. The cities truly do revolve around cars.
