>>1050101My point is manufacturers aren't going to get rich off off recreational riders and commuters. Those people don't want to pay more than a few hundred bucks for a complete bike, certainly less than $1000, and that means aluminum or steel frames, and everything about as simple and cheap as you can get, not lightweight, not fast. Basically, Walmart bikes. Shimano, SRAM, Campangnolo? They're not going to bother. The money is in higher-end bikes, especially race bikes. If pro riders aren't going to use it to race, then there's no one to promote it, which means the non-pros aren't going to buy it. For every 1 pro rider, there must be at least 1000 amateur riders who race in amateur races. They aren't going to be on Walmart bikes with low-performance, no-name components when they race, either, amateur or not. Therefore, regardless of 'efficient' or not, internally-geared hubs are never going to dominate the cycling market, not any more than e-bikes will.
