That is a stupid assumption to make and even more stupid that you’re trying to defend Amazon. It has 4 wheels, so it literally isn’t even a bike. This is obviously an attempt to cut some corner, probably trying to save on gasoline and shove more responsibility to the workers who aren’t being paid anywhere near what their labor is worth.

Capitalism cannot function without paying workers less than their labor is worth, thus creating “profit” margins for rich people to steal from

It appears Orwell is referring to the “pacifists” that think any violence ever, even in self defense, is bad. A radical pacifist, if you will.
