You do little more than clean your chains and change flats. Ah, maybe you replace your own flats and put on new tires. What is your closest estimate to what a decent bike repair schedule; would cost you each year for over like three years.
Three years to a cyclists who rides over 5000 miles a year should run into some more than just normal maintance issues. Pretty much , just regular costs might be chain replacement, tune up, maybe some spoke replacement. Over the course of like five year, one might expect hub or bottom backet replacement. I read somewhere, maintenance costs for a bike is like 2.5 cents per mile. ( Don't know if that includes purchase costs) Cars were like 40 cents a mile. I imagine just like cars, it costs more to maintain a Colagno than a Giant , you factor in things like expensive wheel sets, etc.
