Cycle parts are essential components that make up a bicycle, ensuring its functionality and performance. Key parts include the frame, which provides structure; wheels, made of rims, spokes, and tires for smooth movement; the drivetrain, including the chain, gears, and pedals, which facilitates propulsion; brakes, such as disc or rim types, for safety; handlebars for steering and control; and the saddle for seating comfort. Additional parts like lights, reflectors, and fenders enhance safety and usability. Regular maintenance of these parts is crucial for optimal cycling performance.
