It will please you to know that gears are fitted as standard on many bicycles.

Honestly trying to convince people that a full life can be lived with a bicycle feels a lot like the problem of the cave.

There's a whole world outside the parking lots, but too many people have never even seen it; just pictures of it on travel blogs about Amsterdam, and don't really think it's real.

Edit:

In addition to gears, batteries and motors are a thing.
