Are you "nope" guys speaking from experience, or just hypothesizing? Both are fine, of course.
My father is a big boater so I grew up spending a lot of time around the water, and the buoyancy of some small objects can be impressive. That's what made me think it was impossible. And to be clear, I'm not necessarily expecting a strong bobbing around on the surface, but maybe frame down with just the contact patches of the wheels barely staying at the surface.

I thought it went without saying that this is really just a thought exercise, and I'm not going to risking my life, or anyone else's, for a bike. For a little more background, this ferry crosses the East River, which can get a nice little rip going but generally isn't particularly wide.
