Electric bikes also address issues of traffic congestion, infrastructure, and individual and community health. They are flexible and accessible to a wider range of users, including those who may not be able to use a regular bike.

E-bikes produce 20-35 times less carbon than electric vehicles

Electric bikes, or e-bikes, are highly efficient and produce 20-35 times less carbon than electric vehicles (EVs). According to a study by Walk Bike Berkeley in 2019, e-bikes have a fuel efficiency of 2200 to 3800 MPGe, which is not only 20 to 35 times more efficient in terms of miles per kWh but also translates to a much lower carbon footprint. This means that e-bikes are a more efficient use of batteries than electric cars.

The high efficiency of e-bikes in comparison to electric vehicles is further supported by their ability to go almost 70 times farther than a gas-fueled car per pound of climate emissions. When considering California's electric energy mix, this number more than doubles, with e-bikes able to go over 140 times farther. This makes e-bikes over 20 times more efficient than electric cars in combating climate change.

The low-hanging fruit for zero-emissions transportation is bicycles, electric bikes, and other micromobility options. However, most modern urban and metro areas are designed with cars in mind, and many people view their cars as a status symbol. As a result, electric cars tend to receive more media coverage and attention, even though e-bikes are a more achievable and attainable climate solution for many individuals.

While the manufacturing process of e-bikes does contribute to their carbon footprint, it is important to note that this impact is significantly lower than that of electric vehicles. In France, the carbon footprint of an electric bicycle averages 13 grams of CO2 equivalent (CO2e) per kilometre travelled, taking into account the entire life cycle of the bicycle, including manufacture, use, maintenance, and end of life. This is significantly lower than the carbon footprint of an electric car, which is estimated to be around 35g of CO2e/km travelled per passenger.

In conclusion, e-bikes are a highly efficient form of transportation that produces 20-35 times less carbon than electric vehicles. They offer a cost-effective, flexible, and environmentally friendly option for individuals and communities, making them a big winner in the fight against climate change.
