What do you mean by that? Unless it’s an e-bikes most modern bikes are extremely standardized and IMHO generally better quality than older bikes (unless we’re exclusively talking about fixed gear steel frame ones)
I do not remember the details, I saw a blurb on a bicycling site that manufactures are starting to create bikes that regular people cannot repair.
I think I heard the following over the last couple of years:
* a kind of automatic gear shifting, but very lite weight
* Cables are somehow routed through the frame
* I thought I heard there is a shifter that no longer needs cables.
* And I know about tubeless tires.
* I did hear about using Mars Rover tires for bikes, that should great, but last I heard they were very expensive. Not sure if they hit the general market yet.
All of that to me points to a very complex system.
