Trek’s figures show that electrifying any bike adds about 65kg of CO2e to production emissions. Making a basic commuter e-bike would therefore produce about 165kg of CO2e.
But compared with the manufacturing impact of a car, the differences between a conventional bike and an electric one are marginal. Making a small hatchback produces about 5.5 tonnes of CO2e. An electric version adds another 2-4 tonnes owing to the battery and electric motor. And manufacturing an SUV produces up to 13 tonnes.
However you cut it, compared with other forms of transportation, bikes have a much smaller carbon footprint.
Unnecessary thread IMO
