There were rumours of racing road bikes being outfitted with an electric motor in the seat tube, with a 45 degree gear arrangement in the bottom bracket, and LiPo batteries in the seat tube and down tube.

It always reminds me of someone with very heavy body odor eating a fresh batch of popcorn.

Bad smell with a good smell is still a bad smell.

I wonder how easily this could be converted to run on pure compressed air. I would take a shorter runtime for truly zero-emission transportation.

Could work. But I don’t think you’d want to be near the tank if that little fatigue crack decides it has enough and starts propagating fast.
