Trains and bikes are much more inconvenient. Though bikes are good for close proximity.
There are bikes that have motors, it helps reach further away locations.

Do those motors keep the rain and snow off you?

And look at all these single non-parents trying to tell everyone they should only use a bike…

There are carts you can pull behind your bike that your kids can ride in. Some of them even have up to 4 seats for kids
Also they have fairings for the rider you can buy to be your windshield basically
