A bicycle, commonly known as a bike, is a two-wheeled vehicle powered by pedaling. It is an efficient, eco-friendly mode of transportation and a popular choice for both commuting and recreational activities.

Structure: The core components of a bicycle include the frame, wheels, handlebars, pedals, and drivetrain. The frame is typically made from materials such as steel, aluminum, carbon fiber, or titanium, each offering different balances of weight, strength, and cost.
-
Wheels: A bicycle’s wheels consist of a rim, spokes, and a hub. The tires can vary in width and tread pattern depending on the type of bicycle. For instance, road bikes have thin, smooth tires for speed on paved surfaces, while mountain bikes feature wider, knobby tires for better traction on rugged terrain.
-
Drivetrain: The drivetrain includes the pedals, cranks, chain, and gears. Pedaling powers the bike through a system of gears that can be adjusted to manage different terrain and speeds. Some bicycles have a single gear (single-speed), while others offer multiple gears (geared bikes) for versatility.

Brakes: Brakes are essential for safety and control. Common types include rim brakes, which grip the wheel rims, and disc brakes, which provide more stopping power in various conditions. Each system has its advantages depending on the type of riding
