An idiotic term made up by e-bike enthusiasts on Twitter who are too stupid to pick up a dictionary and realize that the term "acoustic" has to do with only sound or music.
Moron: Check out my new e-bike your acoustic bike sucks in comparison.

Smart person: Does it look like my bike makes music!?

Get the acoustic bike mug.
A fun play on words used to refer to a regular, non-electric bike. It comes from electric guitars and acoustic guitars. There are electric bikes, so why not acoustic bikes?

A term made up by e-bike enthusiasts who know know "acoustic" relates to sound but use it because it's fun. Apparently makes obsessive weirdos angry.
Person A: Yeah, I have an electric bike but today I'm riding my acoustic bike.

Person B: Haha, that's a one. I'm not going to nitpick the scientific accuracy of the phase because I'm not a pathetic dweeb.
