After how many kilometres on average are the CO2 emissions for the production of an eBike (a Bosch eBike system) amortised?

Overall, an eBike has an average carbon footprint of 300 kg-CO2-eq. Around 120 kg-CO2-eq of this is attributable to the Bosch eBike system.
After only approx. 800 eBike kilometres, the emissions for the eBike system are amortised when travelling by eBike instead of by car, and the emissions for the entire eBike after 2000 eBike kilometres.
These figures are average values. They may differ depending on the model.
