Mostly it can't ride, and can't steer, so mankind is like squadrons of bicycles running amok.

We should every one fall off if we didn't ride so thick that we hold each other up.

Horrid nightmare! As for myself, I have a horror of riding _en bloc_.

So I grind away uphill, and sweat my guts out, as they say.
Well, well--my body is my bicycle: the whole middle of me is the saddle where sits the rider of my soul.

And my front wheel is the cardiac plane, and my back wheel is the solar plexus.
