In terms of emission production, bikes are the obvious leader in this category considering they produce nearly no emissions to run.[11] They are also smaller and create less pollution in terms of production.[12] On average, the production of a single bicycle creates around 530 pounds of carbon dioxide, which can be generally offset by about 400 miles of biking instead of driving.[12] There are arguments that bikers need to consume more food, which leads to emissions productions in other ways and that drastically adds to the total emissions produced by bikers in comparison to drivers, but a biker would have to have a diet extremely high in beef consumption in order to substantially offset the emissions benefits of biking.[12] Of course, like any other mode of transportation, feasibility and practicality play a role in the use of bikes in a different setting.
