Just start with small pieces of steel instead of small rocks. It was seventeenth/eighteenth century tech.

Pneumatic tires were completely novel. I want to keep them. All that's needed to make a tire is needle and thread. Oh, and rubber. Which means international trade is needed. Global trade has been a constant since the Bronze Age. It might be nice to try a tire with a casing made from Dacca muslin. From what is known of that fabric it would seem ideal. But the stuff only exists in museums. No one has known how to weave it for about 200 years. Preserving just that sort of knowledge is what Luddism was about.

All the other details that go into current bicycles are just that, details. A derailleur is a series of levers and pivots. Any Luddite mechanic can understand any derailleur. Or at least any mechanical derailleur. Electric derailleurs we won't even think about.

Luddism was always about valuing persons over commerce. Not hostile to nice things. Or more specifically not hostile to nice things made by humans.
