Baffling, maybe. It's a good question, not because the answer is trite but because it's interesting. The invention itself might have even occurred, or parts of it. If you pressed hard enough, maybe you might have gitten a decent prototype built in the bronze age. History has to take its course, in a sense. It has to be.practical and economical to manufacture, acquire and use one. A major part of that is what it takes to build one that's good and cheap enough. Another part is the path (roads, good steel parts like hollow tubes). Then it needs to be invented in a way that can lead to some decent number being made, demand of some sort considering that it still sucks. Enough people need to learn to ride one... There need to be engineers around with an interest... It's dense with trees, but forests assume trees are inevitable. Nothing here is really. Maybe the invention is, on some level. But things usually need to be invented into existence over many iterations, events and chains before they totally stick.
