Of course technically acoustic relates to sound. But in the colloquial fads of hip talk, the implied meaning is relational. IE, acoustic guitar means non-electric guitar. Therefore the you have to think outside the box of some terms used. So non electric guitar and non electric bike makes perfect sense to be called "acoustic" when use colloquially.
Level of education has nothing to do with such phrasing when trying to be whatever the term is for cool person today.
Further to this, I looked up Roland, the makers of digital pianosTHE DIFFERENCES BETWEEN AN ACOUSTIC PIANO AND DIGITAL PIANO
An acoustic piano produces sound with felt-covered hammers hitting steel-wire strings. A
digital piano doesn’t use hammers; instead it features electronic speakers to playback high quality recordings taken from the very best acoustic pianos.
