> Isn't this focused on the young, single, and healthy?
E-bikes are a wonderful thing. In countries with good cycling cultures, the older population cycles more than the younger.
People bike as children and teenagers, then get driving licenses and drive for a few years. Once the novelty of car wears off they start cycling again. It’s cheaper, quicker, easier, and healthier.
> You cannot bike your 3 kids to schools and hospitals during rainy autumn days.
Yes you can. The Dutch do it everyday. Also you don’t need to bike your kids to school, with proper cycle infrastructure, they can bike themselves, sans helicopter parent.
> Some form of "school" starts at around 2-3 y/o. 2-3 year olds cannot take a bus.
There are many types of bikes, include cargo bikes designed to transport multiple young children, driven by one adult. You can even get motor to help you out!
> There is winter, heavy rains, and wind. In most places you cannot rely on a bike all the time.
Dress appropriately! Wear coats! We solved this problem a long time ago. There are plenty of countries where people of all ages and experience cycle year round. In the sun, in the rain, in the wind, in the snow! Don’t limit your cycling to just pleasant weather, by proper clothing so all weather is pleasant.
> In most cities people work far from home, and the early schools the kids go to are also far away. A young family with two 2-5 y/o children will not be able to rely on a bus and a bike, unless they live in some expensive area where everything is nearby and are lucky to have jobs at the same place.
This is very US centric world view. The US has a strange obsession with spreading everything out as much as possible, ensuring that you have to spend your life in car going from A to B. I would argue that more enlighten approach is to put stuff close together, so you can spend your time doing stuff, not travelling to stuff.
