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?
