Electric bikes are the most environmentally sound means of motorized transport in the world today. They come in many shapes and forms and are accompanied by a small battery-powered motor that can make hills manageable, journeys swifter, and longer trips more viable. As they grow more effective and affordable, e-bikes are increasingly drawing people out of more polluting modes of transportation, such as driving solo.
E-bikes are all the rage in China, where millions of people use them to commute and e-bike owners outnumber car owners by a factor of two. The trend dates to the mid-1990s, when China’s booming cities put strict antipollution rules in place. These pedal-motor hybrids are on the rise in many parts of the world, as urban dwellers seek convenient, healthy, and affordable ways to move around congested cities.
An e-bike’s battery gets its charge from the nearest outlet, tapping into whatever electricity is on hand—from coal-based to solar-powered. E-bikes have higher emissions than a regular bicycle or simply walking, but they still outperform cars, including electric ones.
