it's the frame that's surprisingly - and consistentnly - wrong. You'd think two triangles would be pretty easy to repro; once you get that the rest is easy. It's not like he's asking "draw a pelican on a four-bar linkage suspension mountainbike..."

This is older, but even humans don't have a great concept of how a bicycle works... https://twistedsifter.com/2016/04/artist-asks-people-to-draw...

Wouldn't this be more about being capable of mentally remembering how a bicycle looks versus how it works?

This reminds me of Pictionary. [0] Some people are good and some are really bad.

I am really bad a remembering how items look in my head and fail at drawing in Pictionary. My drawing skills are tied to being able to copy what I see.

I think it’s difficult to draw a bike exactly because you remember how it works rather than how it looks, so you worry about placing all the functional parts and get the overall composition wrong. Similar to drawing faces, without training, people will consistently dedicate too much area to the lower part of the face and draw some kind of neanderthal with no forehead.

is it possible to have greater success with the specificity? I don't think i ever drew a bike frame properly as a kid despite riding them and understanding the concept of spokes and wheels...
