Take your bike to your local bike shop for a quick safety check. They can determine if it is safe to ride or needs any additional maintenance. Ask them for an estimate first before the work is done. They can call you if they discover something major in the inspection process. The cost of a basic tune-up is approximately $50 to $75. Don’t assume just because you haven’t ridden your bike that it is still tuned-up. Grease and chain lubrication can dry over time, and cables can loosen up if bumped or moved around.
