Bicycle repair involves maintaining and fixing various components of a bicycle to ensure it operates safely and efficiently. Common repairs include fixing flat tires, adjusting brakes, and tuning gears. Basic tools like wrenches, tire levers, and pumps are often used in the process. Regular maintenance can prevent more significant issues and extend the life of the bicycle. It's essential to check the air pressure in the tires, lubricate the chain, and inspect the brakes periodically. Learning simple repair techniques can empower riders to handle minor problems on their own, enhancing their cycling experience.
