Frame: The frame is the main structure of the bike, typically made of metal (such as steel, aluminum, titanium, or carbon fiber) or sometimes of other materials like bamboo. It provides support for all other components and determines the bike’s size and geometry.
Wheels and Tires: Bikes have two wheels, usually made of aluminum or carbon fiber rims with rubber tires. Tires come in various sizes and treads depending on the type of bike and intended use, such as road biking, mountain biking, or commuting.
Brakes: Bikes are equipped with braking systems to slow down or stop the bike. Common types of brakes include rim brakes (such as caliper brakes or cantilever brakes) and disc brakes (mechanical or hydraulic), which provide better stopping power and performance, especially in wet conditions.
