I'm not sure that point revolves around the manufacturing of the car and bikes, even though that should be included.
There was a study, that sadly eludes me, that suggested that if you need to travel more than 2km to do you grocery shopping, then it would produce less CO2 to get in your car and drive, compared to walking.
The reasoning is that you need to consume some amount of food to generate the energy required to walk to the store and back. The amount of CO2 used to generate that food, and the additional CO2 you exhale, would be larger than what a modern car would produce, traveling the same distance.
I believe that the same argument that would make multiple people in an EV carpool more environmentally friendly than bikes. But that's also the case with regular cars.
