How does a bicycle work?

Indeed, sir. At its core, a bicycle operates through the elegant interplay of pedals, gears, and wheels. When you push down on the pedals, this motion is transferred via the chain to the rear wheel, causing it to rotate, and thus propelling you forward. The front wheel is steered by handlebars, allowing for direction changes. What makes a bicycle particularly remarkable is its simplicity; with just two wheels and some clever mechanics, it enables swift and efficient travel, a testament to human ingenuity.
