I have yet to replace my chain on the 3000+ miles I've logged on my bike
Who knows how many miles I did before getting a cyclocomputer and how many miles the bike had before I bought it at a garage sale
I still have the original cassette - no need to replace any time soon
My expenses on my bike since it was purchased have been roughly $100 including the $35 to buy. I've spent more on oil changes for my car since I bought that bike
Equipment costs can be expensive - if you're going for a high performance bike
But it doesn't have to be that way (hell, I'm riding on a lugged steel frame
).
The better comparison would be to compare a scenario when you're likely to be substituting saddle time... How much will it cost you in fuel to do four 3 mile trips (all starting with a cold engine) daily for a week.
It's not like these expenses go away if you converted your bike to a lightweight EV
