 Bill Sloman's original claim was: "... an e-bike doesn't generate any
CO2.", which is patently untrue.

It isn't. An e-bike charged with electricity generated by a renewable source won't generate any CO2, and in the situation I was talking about it clearly wouldn't have.
You want lump in it's manufacture, and the construction of the road or bike path it runs on, which is a stretch

Had he said : " ...an e-bike doesn't
generate any more CO2 than other comparable modes of transport, that
would have been nearer the truth.

No, an e-bike charged by wind turbines and solar panels isn't going to generate any CO2 emissions while it is being used move people - and the contents of their bike bags - around.
If you want a pedantically correct claim - that's it. You've invented a different claim, which you want to pass off as the one I made.
