So why do feel there is a need to carry kids to school by car? In inner-city London, no less.

Also, you can get a working car for 1k€$ but that's obviously not the full cost. You need to pay for parking, maintenance, insurance, taxes and, finally, gas.

1. Yes it can carry three children if you get a cargo e bike, those cost slightly more, but still cheaper than a car by far.
2. Yes that cargo e bike can carry a full sized refrigerator it can carry groceries
3. Are you afraid the rain is gonna melt you? I bike to work in the rain and I’m still alive and well, I just wear a poncho to keep dry.
4. Ya you can get a car for 1k but what about the recurring costs of insurance, gas, repairs, etc…

If you have 3 kids and a car, I'm sorry, you chose poverty
