But if you look closely, there are several errors, and those errors are revealing. For example, the rear center-pull (?) brake is mislabeled as the seat stay, and the big gear on the back is mislabeled as the rear brake. There is a label for a spoke that is pointing to blank space.

In many modern bikes, of course, a rear brake can be found back there, but not in this diagram. Instead this system has combined a typical position for a modern disc brake system with a diagram of an older (though still in use) caliper (or similar) system. The system doesn’t actually understand how the various parts function.

And of course there are literally hundreds of labeled bikes on the internet as a quick Google Image Search would reveal. (Which is why my usual test here has been a tandem bike, to make things a little more challenging.)
