Balenciaga motorcycle Vs. Balenciaga city backpack?

Im confused, Is there any difference between b. motorcycle and B. city bag? are they impossible to tell apart?

What about Balenciaga weekend bag? Which one is it?

Answers: 
in good health there all motorcyce pouch, the is the bag called the first which is small and here is the le dix which is small too. The city (which i want really bad) is like a medium size. The weekend one is one of the big ones... they adjectives look the same but have different sizes.
