My bike just turned 9000 miles in a couple of months shy of 3 years. I haven’t spent a nickel on repairs or maintenance so I decided to take it in to my local bike shop for a tuneup. It was put up on his rack and checked it over. The bike mechanic said I don’t need a tuneup yet . The tires, breaks, chain , wheels and the rest of the bike is fine. No charge, but come back in the spring and he will see if a tuneup is needed then. Amazing bike. Ed
