CVTs on automobiles were definitely released before all the issues were fully resolved, no question there. Though I think for fixed machinery and personal mobility, CVTs have substantial benefits, if they are properly engineered for the task. The major drawbacks being efficiency and packaging.

Supposing maybe Bafang develops on this present idea and makes an integrated CVT hub motor, an ideal implementation would have the torque sensor adjusting the ratios to keep the human at a constant effort.

Would it result in the pedals having nearly zero relationship to the actual effort of moving the bike, being essentially spin class but in public? Almost certainly. CVTs automobiles aren’t exactly considered fun to drive. But bikes for transportation is a key segment, and some people just want a bike for points A to B.
