Reminds me of the exhibit of inventive pictures made by students of various ages in the Bycicle Museum in Sakai, Osaka, Japan.

For example, one drawing was of a bike / submarine hybrid - from a kid who likely wanted to explore the ocean.

The bicycle one is always fun.

I suspect if you know that a bike frame is typicall two triangles for strength you’d get it right, some of those are hilarious though.
