Hi,
first, for me the UX is a bit small, hard to read, I don't have the best eyesight though.
I do like the theme a lot as a gravel cyclist of sorts, but I have some forearm issues that make me not wanna mash space button that much. In e.g. cookie clicker I think over time the auto-clickers end up clicking for you mostly so that you don't have to, maybe that could work here, or it happens at some point that I didn't reach.
Maybe you can incorporate saddle sores into your game and some way to remove them.
I didn't get that far.
Hope it helps.
