Who is the king of all bikes?

Excuse me, I couldn't help but overhear your conversation about bikes. It sparked my curiosity, so I must ask - who exactly is being referred to as the 'king of all bikes'? Is this a title given to a particular model or brand that stands out among the rest for its exceptional design, performance, or popularity? I'm genuinely intrigued and would love to hear more about the bike that holds such a prestigious position in the cycling world.
