False. Trek is not the top brand in the world if you're going by sales as any other thing you could argue would be subjective so I'm going to go ahead and assume you are talking about sales. Giant Bicycle is the number one selling brand of bicycle in the world.

Coincidentally, I like Trek mountain bikes but their road bikes I do not have a taste for. Until you get up to the OCLV series of course! Then they pwn. lololol
