They use standard parts that you can find in an any abandoned bike store or department store
“Standard” in that there are multiple incompatible “standards” for wheels, hubs, chains, cranks, chainrings, shifters, derailleurs, derailleur hangers, brake mounts, brake fluid, handlebars, seat posts and probably 50 other things I’ve forgotten.
And department store bikes ignore most of those standards and do whatever is cheap.
I’ll stick to Decathlon MTBs. Decent enough and veeery widespread here across Europe, probably a better than 50% chance of breaking into a house and them having one of those in the shed/garage. Decathlon itself has hundreds of fully assembled bikes in their big stores. Finding replacement parts would be a piece of cake.
