Bike maintenance is a matter of what kind of equipment you’re riding, how far, what conditions, how much you weigh and how strong you are. When I was putting 40 miles a day commuting, my cheap bike needed maintenance about once every 2-4 weeks depending on the weather and taught me that I fucking hate cleaning and repacking my bottom bracket.

The proliferation of Ebike caliber equipment changed a lot at least for durability and comfort.
