And in Berlin you can cycle! I'm not a regular cyclist, but on holiday I felt totally comfortable renting a bike and using the bike lanes to get around.
It's not quite a fair comparison.
Compare Pittsburgh suburb (https://goo.gl/maps/bFBWcsJ6EeL1kgVe7) to the suburbs of the town that I was born in (https://goo.gl/maps/ktkWzAUa3tyz37hQ7).
This is an even better example: https://goo.gl/maps/cAECdLXaBVoErtsFA vs https://goo.gl/maps/oBmruFK2Sqaxg6TW7
EDIT: Same goes for the Bay Area, staying by YC offices for the interviews was depressing too. Look at this: https://goo.gl/maps/ERCkS7zrHw8tM2or9
You can certainly cycle in New York. Cycling has increased dramatically in New York City over the past decade or so with the installation of more cycle-friendly infrastructure, including over 100 miles of protected bike lanes, city bike sharing, e-bike rental apps, etc.
