That said, I am mainly referring to modern gearing and injection systems. Basic maintenance is probably well within what folks can do. But that is true of cars, as well. No?
there’s some truth. higher end bikes have electronic throttle and stability control. but still the bulk of bikes and the systems are 80-s tech . abs disk brakes . efi. controls are still mechanical and hydraulic (no software) . engine are traditional cam valves and accessible . transmissions are still 1950s tech
100% of a mid level bike and 80-90% of a premium bike can be self serviced
I'm a little surprised that brakes and such aren't electronic. I've seen wireless shifters on bicycles. And the gearing is something I would fully expect to be beyond most home mechanics. That is, I'm surprised the transmissions haven't gotten a bit more involved.
I suppose the market catered to itself, and things were kept more home serviceable for longer?
