I don’t know what you mean by tune up of the bike. For me, as long as the bike is in good running condition then there’s no need for a tune up. When the tire looks soft, I will have the pump fix that. But for other problems like the loose chain, I couldn’t do that myself and I have to bring the bike to the nearby mechanic. I know that it is more enjoyable to ride when you feel that your bike is in good condition. However, as I said, when nothing is wrong then there’s nothing to worry about.
