- Frame: The main component of the bike, the frame is the skeleton that holds everything together. It is usually made of aluminum, steel, or carbon fiber.
- Wheels: The wheels consist of the rims, spokes, and hubs. The rims are the circular outer part of the wheel where the tire sits. The spokes connect the rims to the hubs, which are the central parts of the wheel that rotate on the axles.
- Tires: The tires are the rubber coverings that surround the rims and provide traction with the road or terrain. They come in a variety of sizes and tread patterns for different types of riding.
- Fork: The fork is the part of the frame that holds the front wheel. It consists of two blades that extend down from the head tube of the frame.
- Handlebars: The handlebars are the part of the bike that the rider holds onto. They come in various shapes and sizes and can be adjusted for different riding positions.
- Stem: The stem is the component that attaches the handlebars to the fork. It can be adjusted for different handlebar positions and angles.
- Brakes: The brakes are the mechanism used to slow down or stop the bike. They can be either rim brakes or disc brakes.

- Derailleurs: The derailleurs are the components that move the chain between the different gears on the bike. There is a front derailleur for the front chainring and a rear derailleur for the rear cassette.
- Crankset: The crankset is the component that converts the rider’s pedaling into motion. It consists of two or three chainrings that attach to the pedals and rotate the chain.
