The first step to maintaining your bike is to give it a thorough inspection. Make sure all the moving parts are in working order, check all the cables and brakes, and ensure the tires have enough air. After this, you should lubricate all the moving parts and clean the frame, rims, and drivetrain. Finally, check all the fasteners to make sure they are tight, and adjust the brakes, saddle, and handlebar if necessary.
