Front bicycle wheel in all Argon examples is still wrong. This bicycle will not be stable. Axis of rotation of front wheel needs to be in-front of axis of rotation of steering wheel. Frontier VLMs still do not understand how bicycles work.

Check the "high" thinking output again. For what it's worth, it's there.

However, how the front fork rake affect stability is I believe a little complex. I doubt this old article is the last word on the subject, but it's a great read nonetheless, and note especially the ultra-stability of the reversed fork bike!
