Dynamics is technically considered a branch of mechanics, but you're absolutely right—to be more precise, dynamics

Speed and force—along with a whole host of other physical properties—are vector quantities, which basically means they possess both magnitude and direction. When you combine them, you’re essentially using the parallelogram rule. It’s a bit tricky to illustrate that visually here since I can't exactly sketch it out for you on the fly! But more importantly, what we're looking at is how velocity interacts with external forces. The faster you're moving, the more even a slight breeze will push you off your intended path. In your case, it seems like when you let go of the handlebars with just one hand, you weren't applying enough counter-force to offset that wind pressure. To keep your bike traveling in a perfectly straight line, you actually have to actively fight the wind by steering slightly into it—essentially applying an equal and opposite force to maintain your course. I hope that clears things up! Honestly, once you get the hang of it, it isn't nearly as daunting as it sounds—we aren't exactly dealing with quantum physics here, just some straightforward classical mechanics...🙂
